[Mr. Brown did not make his speech available for reprint.] Productivity is the Answer - Always Was; Always Will Be When Bill Balaz invited me to speak here this morning, he asked me to examine the three most important issues Consol will face over the coming decade. There are more than three. But the more I thought about that question, the more I realized all our issues come down to only one. As I reviewed the U.S. coal industry over the past ten years, and as I thought ahead into the year2000, one thing stood out. Not markets. Not government regulations. Not record tonnages. But productivity. The recent history of American coal is a tale of productivity improvement. It is a story that needs telling. And understanding. Not just for the good of the coal industry, but for the benefit of the American economy. Americans today do not appreciate the value of productivity growth. I don't say that lightly. As I review recent debate over American industrial competitiveness, as I look at certain legislative proposals, I see disturbing trends. It's not that anyone is against productivity per se. But many people seem to fear the very processes that enhance productivity. Twentieth century America enjoyed unprecedented growth in productivity. And in personal standards- of-living. Those two go together. This century has been one of change. Demographics. Education. And technology. Many new industries-cable television, computer services, telecommunications, for example-have grown from mere dreams to billion- dollar enterprises employing tens-of-thousands. And some older industries have declined. The nature of work has changed-from manual work to know- ledge work. From agriculture, to manufacturing, to services. In the mid-1960s. AT&T employed more than one million people. These were not high-paying jobs: telephone operators, linemen and equipment assemblers. Today, the successor Bell companies and their new competitors employ no more than a few hundred thousand. Because of automation. Because of enormous gains in employee productivity.

PRESIDENT MOSES: I think this will conclude our program for this afternoon, unless you have some- thing else. Mr. Holman, will you tell us what you are doing in the way of your local chapter, around Dawson? W. C. HOLMAN: (Chief Engineer, Phelps-Dodge Corporation, Dawson, New Mexico.) We have organized a local chapter of the Rocky Mountain Coal Mining Institute, and we invite all foremen, fire bosses, shot firers or anybody interested, either on the surface or in the mine. I think at the last meeting we had sixty to seventy men present. We hold meetings once a month; usually on a certain set Tuesday or second Friday of the month, or so on. We have a President, a Vice-President and a Secretary-Treasurer. There are no dues connected with it. We aim to take up the' papers that are presented at the various meetings of the Rocky Mountain Coal Mining Institute, and also any other subject that would be of interest, connected with our own mining operation. We usually ask two or three men to pre- sent papers, rather than one man. We find it difficult in getting one man to work up any subject, but two or three men work up very interesting papers. While we have just recently organized, we aim to have luncheons in connection with it, and possibly once a year a banquet or .some similar activity that we think would interest the men. We feel it is going to be a great help in carrying on the work of the present organization in presenting the activities around the mines. PRESIDENT MOSES: I thank you, Mr. Holman. Has any one any- thing to bring up at this time? MR. LITTLEJOHN: I would like to ask Mr. Holman if the Institute or the Chapter there is confined to Dawson alone, or open to other camps in New Mexico? MR. HOLMAN: At the present, Mr. Littlejohn, it is just confined to our own camp, although we intend to invite the members and the officials of the other camps later on, perhaps. Especially, if we gave a banquet, no doubt we would invite the others. MR. LITTLEJOHN: Is there any other Chapter in New Mexico besides yours in Dawson, Mr. Holman? MR. HOLMAN: None that I know of, right now.

CHAIRMAN LITTLEJOHN: We have with us this afternoon, Mr. D. W. Rockey, of the Industrial Educational Organization, who would like to occupy a few minutes of our time. There is still an hour left, and there is a lot more talking to be done, and when the time is up you can go. D. W. ROC'KEY (U. S. Vocational Training Bureau, N. M.) : Mr. Chairman and Gentlemen: I am sorry to say I am not more closely connected with the coal mining game. I am interested in it because I am interested in a great deal of educational work being done in New Mexico. Two years ago, this Institute appointed an Educational Committee to investigate the opportunity for education in coal mining, and you have the report of that committee; it was issued in May 1924. Mr. Littlejohn, Mr. Moorhead of the Phelps-Dodge Corporation, Mr. Dickinson, and Mr. Miller, I think, of the C. F. C I., and Mr. Pryde, were members of that committee. They investigated the work being done in Safety, Training, First- Aid, and other topics, and made a general survey of the educational problems that might be said to be of benefit to the coal operators and to the coal miners. I believe, if I understood Mr. Moorhead correctly, while this report was accepted the committee was not discharged; but everyone seemed to be a little in doubt as to whether this activity should continue. My plea here directly is, of course, to ask that they be made a permanent committee, and asked to report to you at the next meeting in February on what has been accomplished in carrying out the program that was advised by the various companies, and what success, from a standpoint of improved work and financial return to the company, has been had. I believe that the whole trend of your discussion here has shown the need or the opportunity for improved production through education. For instance your mechanical loader the need of men who are experienced along mechanical lines, rather than the old pick and shovel methods, and the need of better understanding of your problems, just as in your safety lamp discussion that came up in the report of your Safety Committee. We have also developed a new phase, a new may of getting at some of your problems at Dawson this year, that has not been covered previously. I want to ask Mr. Holman here to tell you what is being done as a starter. Remember, we have not worked this out. He will tell yon how we are making a preliminary start in training inexperienced miners with the idea of cutting the accident record and keeping the production of inexperienced men at a higher level. If you are interested in that, I would like to suggest that this committee be requested to investigate some of these things very carefully. The State of New Mexico was willing to put five hundred or a thousand dollars into this training program as an experiment. We are willing that the Institute should have the credit for it, but we want it carefully surveyed so at your next meeting or some subsequent meeting, they can say this has been a feasible project and worthy of consideration. Mr. Holman, will yon tell us a little about this? (Applause.) MR. HOLMAN: We had an idea that by putting a green man in the mine with an experienced miner, the green man would probably learn something, and not get into trouble, etc. We decided to take a certain portion of one of our best mines, cross entry room work, and establish an underground school. We picked one of the assistant foremen who was well trained in our particular mining methods, and any green man who was employed was put into this school. He was paid a salary and he trained each and every man. Each man or two men world be working in a room and we paid them the regular contract price; they were trained how to shovel coal, pick waste and various other things. Some would stay in there a month and be transferred to other portions of the mine or other

At nearly all of the copper smelters in the Southwest, at some time, calculations have been made having in view the economy of replacing fuel oil with pulverized coal as a heat-producing medium for smelting operations This matter has been, and is more so now than at any time heretofore, of very great importance. Due to the intensive development of oil-producing areas of the world and the tremendous use of fuel oil for many purposes, it seems that before many years the supply of oil will become so small as to prohibit its use for such operations as smelting. This may be caused by prohibitive prices, or even by government decree as a conservation measure. In the event that the use of fuel oil becomes out of the question, the copper companies have just two alternatives: the use of pulverized coal or electricity. The copper companies of the Southwest produced an average of 808,400,000 pounds of copper per year for the war years of 1916, 1917 and 1918. This figure is, of course, a higher one than has prevailed since the war, but at the present time nearly all of the mines and smelters are getting back to capacity. There is no doubt whatever that the consumption of copper is going to increase, perhaps for the next ten years. This means that more copper mines will be discovered and developed, and that the mines which are now producing will be called upon for a greater production. This all tends to show that the mine manager who is looking ahead must develop some substitute for fuel oil in the event of its use becoming prohibitive, and all indications seem to point in that direction. The only coal which is commercially available to the smelters in the district under discussion must come from Colorado and New Mexico. These coals are high in ash and volatile matter and comparatively low in calorific value. The proximity of the smelter to the coal mines is a large factor in determining which fuel is more economical. Most of the smelters within two or three hundred miles of the coal mines find it more profitable to burn coal, while those at greater distance find that the higher freight charges on the coal make the use of oil more economical.

MR. MONAY (Vice President Kinney Coal Co., Scofield, Utah): The past year and a half has witnessed a series of coal mine disasters in Utah and Wyoming, concentrated into the short space of a few months, following a long period of years in which the industry was comparatively free from devastating calamities. The natural result has been a hysterical activity on the part of bureaus, commissions and professional reformers who know little about coal mining from a practical standpoint. This activity has been met by the industry in Utah with an attitude of submission, no doubt the result of the fear of being misunderstood by the public. But it is my firm conviction that the lives and property of the coal industry will find their surest guaranty of protection in the humanity, and in the self interest of those operating and working in the mines, rather than in governmental regulation. Inelastic, inflexible blanket statutes and rules will simply stifle and hamper the initiative and progress of our industry in working out its own salvation, under the varying and changing conditions of different localities, different conditions, and in different mines. We who have spent our lives in digging in the mines and operating them, know more about this business than anyone else and I believe it is time for us to speak up and no longer sit meekly by while inexperienced bureaus and unskilled commissions make up laws, rules and regulations for us which when made are on the books to stay, even though in a short time they may prove inapplicable, in whole or in part, or be superseded by something different, and which in some cases create new dangers or lull us into a false sense of security. Shortly after the Castle Gate explosion in March, 1924, a new set of safety rules was issued by the Indus- trial Commission of the State of Utah to become effective July 1st of the same year, the most important of which prohibits the use of black powder in any mine--gaseous or non-gaseous; prohibits the use of open flame lamps in any mine-gaseous or non-gaseous; and requires that rock dusting in all main haulage ways as far as the freezing point and required that all mining machines be equipped with water to be applied while cutting. These rules have been characterized as "Utah's Monument to her Dead Miners" in a large poster spread broadcast over the country from an office in New York that styles itself the Association for Labor Legislation. In reviewing the coal mining history of the State of Utah, in the year 1900, a serious disaster occurred at Winter Quarters. The cause of the same is believed to be an explosion of powder that was stored in the mine, which was a common practice in the early days, and from that time until the Castle Gate disaster, March 8, 1924, a period of some twenty-four years, no explosion of any kind occurred in this district. During all this period open lamps were used, considerable black powder was used, rock dusting was unheard of, sprinkling with water was very generally done-all without any catastrophe. Since the adoption of the new rules, we have 'had a very violent explosion at the Carbon Fuel mine in Spring Canyon. At the time of this explosion, 3,000 feet of the main slope had been rock dusted several times between July 1st and September 21st. The second left entry, which is a main haulage way, a distance of 3,000 feet was completely rock dusted on the date of the explosion. This mine is not considered extremely gaseous, yet an explosion as violent as that of the Castle Gate mine occurred. Some thirty men who had been loading coal in various parts of the mine on this Sun- day, the day of the explosion, and other men employed in rock dusting the second left entry, had just left the mine a little while before it occurred, and no abnormal condition in the mine was noted. At the time of the explosion five machine men were in the mine.

The production capabilities of today?s longwall systems have resulted in significant increases in retreat rates. This has in turn resulted in a heightened demand on panel development rates to assure that subsequent panels are completed in time to avoid a longwall production outage. As a means of reducing the pressure on the panel development activity a trend has developed towards the use of wider face lengths. The aim of using a wider face is to reduce the longwall retreat rate without sacrificing productivity and thereby reduce the pressure on increasing panel development rates. However, as the face width increases so too does the number of hydraulically powered roof supports that are required to control the longwall face roof. This increase in the number of units inherently translates into increases in the level of required maintenance relative to the multitude of mechanical and hydraulic components, and an increase in the time required for tear-down and installation time during the moves between panels. An obvious method of mitigating the maintenance and move-time impacts of wider faces is to employ the use of individual roof supports having a wider center-to-center spacing. This practice would serve to minimize the number of roof supports and maximize the time availability for longwall face production. With this target in mind a joint research project with DBT was initiated in 1998 to study the feasibility of using 2 m wide shields to replace the then standard 1.75 m wide shields. After four years of comprehensive work, the technical team from DBT and RAG American Coal completed the design and development of a prototype shield that would later become part of the world?s widest longwall face employing the use of shields having a spacing of +2 meters. The final spacing of the shields actually became 2.058m in order to match the standard pitch of the rack bar shearer haulage elements on the conveyor. In July 2002, the 2 m wide shields were successfully installed in LW-46 panel at RAG Cumberland mine in the U. S. The authors in this paper summarize the design considerations of and operational experiences with the world?s widest longwall face using +2 meter wide roof supports.

PRESIDENT WHITESIDE: If the chair may be pardoned, he would like to say he knows something of the work of this committee, and I assure you that they have all worked faithfully and hard, holding meetings at least every other day, and sometimes oftener, hustling money and going through all the different work necessary to bring about and to make a successful occasion of this kind, and I-who really acted as an outsider and viewed their work-was certainly appreciative of their efforts, and I know you would have been had you been able to see how hard they all worked. One of the sad things in life always is when one becomes a "has-been." I have been more or less active in the work of the Institute ever since its in¬ception. Just why the high honor of President was conferred upon me I have never been able to fathom, but my time is about over and I am about to join the "has-beens," and while the position naturally has entailed a certain amount of work, it has been very pleasant work, and when one has the hearty co-operation of his fellow workers, such work is always a pleasure. It is, therefore, with a certain amount of regret that I lay down the gavel and take it up again to present to my successor; but in doing so, I wish to thank you, one and all, for your very hearty help and co-operation, and to wish my successor, Mr. George B. Pryde, all the possible success that can be his. Mr. Pryde. (Applause.) MR. PRYDE: I will make no extended speech at this time. I think possibly the next year I will have enough opportunity to do that; but I had a letter from my friend, Murphy, before this meeting, and he thought we were going to have a very good meeting; but I don't know the motive behind his letter. (Laughter.) I remember the story about the Scotchman who went to see the doctor, and the doctor said: "Sandy, you drink any?" "Oh, yes." "Well," he says, "you have got to cut that out. Do you smoke?" "Oh, yes; I smoke a great deal." "Well, you will have to cut that out also." And Sandy picked up his hat and started for the door. "Wait a minute, Sandy; you haven't paid me for my advice." "Yes, but I am not going to take your advice." (Laughter.) But I am deeply appreciative of the honor you have conferred upon me, electing me to be head of this Institute for the next year. I have belonged to this Institute, I should say, ever since it has been organized. This present session especially has been a very good session. As I look back over the different meetings, I think this one stands out among all the others in the papers presented and the spirit of co-operation that prevailed among the members here, and I am not going to ask your co-operation during the year; I am sure I will get it from all of you. I want to thank you for the honor conferred upon me. (Applause.) MR. WHITESIDE: The retiring President did not quite follow the reading of the by-laws, I think, in which it says that immediately after the election of a new President, the new President shall assume office, and I got so busy I forgot all about that. The committee which the chair decided to appoint is as follows. This is to formulate safety rules: For Utah, John Crawford, William Littlejohn; for Wyoming, Peter Patterson, Glen Knox; for New Mexico, William Risdon, Allan French; for Colorado, James Dalrymple, J. C. Roberts; and last and surely not least, as chairman of the committee, Mr. George B. Pryde. (Mr. Pryde later appointed D. Harrington as a member-at-large.) C. M. GODDARD: Mr. Chairman, we all realize that in a gaseous mine the application of, safety measures transcends everything else. Machinery is installed 100 per cent safe, as they might say, to take care of any condition

Please note all Proceedings of the Institute were taken verbatim by stenotypists from Hyatt & Associates of Denver and editing has been minimal. MR. MORTENSEN: On behalf of the Rocky Mountain Coal Mining Institute, I take great plea¬sure in saying good morning to you at Vail. With a few clouds in the sky, at least we won't get sunburned. We won't have to worry about our kids in the swimming pool, perhaps. It is delightful for me to have been able to have represented the Rocky Mountain Coal Mining Institute for the year 1982-1983. This has been our 71st year and this is our 79th meeting. In recognizing the attendance here, that dinner we had last night, and some of our entertainment must have gotten to some of us, or it is a little early. But I'm sure as the day goes on, and with the speakers outlined, it will be very beneficial for those who do attend. We do appreciate your attendance. I'd first like to make an introduction of our head table. Doris Finnie, she is our executive secretary. As most of you are aware, Gussie Whiteside retired as secretary. This will be the first time since the Institute started that there has not been a Whiteside present at one of our conventions. I'm sure Gussie would appreciate any calls or letters that any of you would care to make to her. Doris, I might add, has been a great help to me and all of the people who have been working on the program for the Institute this past year. There's been lots of reorganization and we are very pleased with Doris's ability to take hold from Gussie without any waves. Much credit must be given to you Doris for this and we do appreciate the help you have given us and believe me she has kept us out of trouble. Next, we have Art Neill. He is our vice president of the Institute from Montana and he also works with Western Energy Company. We appreciate the help that all of these session leaders and chairmen give to us. We have other names on the head table, but they will fill in as the morning goes on, so we won't bother you with any of those at this time. To set the stage for business, first I would like to call on Doris for a motion to approve the minutes of last year. MS. FINNIE: Thank you, Vernal. Mr. President, I suggest that the reading of the minutes be dispensed with and that the members refer to pages 9 through 80 of the Proceedings for the 78th regular meeting of RMCMI, as published MR. MORTENSEN: Thank you, Doris. Do we have a motion to so approve? MR. LINVILLE: I so move. MR. MORTENSEN: Loren Linville so approved. Do we have a second? MR. GARR: Second. MR. MORTENSEN: All in favor say aye. (Audience responded affirmatively.) MR. MORTENSEN: Those opposed? Hearing none, the motion is carried. I'm sure glad we didn't have to read those 80 pages. Is Doug Hammer in the audience? He was going to give us a list of new members of the Coal Institute and ask for your approval. But because of his absence, the names will be listed so that you can read them at a later date, I will entertain a motion that we approve the new members who have joined the Institute. Do I so have a motion? MR. BERNSTROM: I would make that motion. MR. GARR: I second. MR. MORTENSEN: Do we have any questions? All in favor¬ (Audience responded affirmatively.) MR. MORTENSEN: Any opposed? Hearing none, the motion is carried. Next, we'd like to proceeed with our Nominating committee report from the chairman, George Nugent, and the election of next year's officers. George, would you please take the stand? MR. NUGENT: Mr. President, and members of the Institute, your Nominating committee consists of five past presidents of the Rocky Mountain Coal Mining Institute. From Colorado Roy Coulson; from New Mexico, Bob Wilson; from Utah, Bob

PRESIDENT LITTLEJOHN: We have with us a gentleman from Utah, who is familiarly known -as the "Mudite King," Mr. Reid, of the Lion Coal Company. Here is a letter I would like to read, and probably Mr. Reid will give us an idea of his Mudite machine, or the results he is obtaining. This question was brought up in Rock Springs, Wyoming, but Mr. Reid was not there personally during the discussion, but Mr. Burnell, who is general superintendent of the Lion Coal Com¬pany, as much as he possibly could, described the system and its effects. I believe Mr. Reid will probably be able to give a somewhat clearer statement this afternoon. This letter is from the Coal Mining Inspector of the State of Utah, John Crawford. "February 10, 1925. "The Industrial Commission of Utah, Building. "Statement of John Crawford, Coal Mine Inspector, in regard to Muditing in Coal Mines: "That Muditing used in connection with our present sprinkling system in coal mines is the missing link to the system we have had heretofore, because the water applied by the former system began to dry out, in heavy air currents, the moment it was put on. Consequently the dust that had been humidified by sprinkling, came back to its natural condition, and if anything, the combustible parts of it, in my opinion, were more intensified than previous to being wetted down. "The advantages that Muditing has over the old system of sprinkling are: "1st. The dust that is on the roof, timbers and sides of the entry is washed completely off and rolled up in the Mudite solution which entirely destroys the wings, crudely speaking, of the fine coal dust. "2nd. Sprinkling with the Mudite system, the water and mud is of greater extent than could be applied with a hand hose by a sprinkler. This sprinkling can be done while the mine is in operation, just the same as if water alone was being used. "3rd. The Mudite solution, when dried out, leaves a coating which serves as an armour to the coal, so that in the event of a local explosion, the inflammable matter on the coal is non-combustible; whereas, if that same coal had been sprinkled with water only, and made free of dust, the heat would have the same effect on the coal as it has on a stove when coal is thrown into it-instantaneous combustion. "Therefore, it is my opinion that the Mudite system is the missing link to the perfecting of our sprinkling system here in Utah. "(Signed) JOHN CRAWFORD." Mr. Reid has with him a few sam¬ples of his Mudite, after it has become solidified, taken from the floor, as I understand it. It is interesting. We have a few minutes to spare to good advantage, were we to ask Mr. Reid to give us an idea of his machine, as briefly as he possibly can, and also what he thinks the effect of the Mudite is compared to dry rock dust. Mr. Reid. (Applause.) MR. W. J. REID (Lion Coal Company) : I came down here with no intention of making any talk on Mudite. However, there being so many people that have seen Mudite at Wattis

Railroads, attempting to increase their tonnage without adding new lines, have for some time realized there is a definite relationship between increasd haulage efficiency, and constant communication with each moving unit that operates along their roadbeds. Elaborate radio communication equipment has been devised for this purpose, and is rapidly being installed. Coal mines are faced with similar haulage problems and have sought this constant contact through the use of telephone systems, and dispatcher stations. Often the fixed mine telephone system is unsatisfactory, since the desired person is not present at the phone when needed. Dispatchers lose contact with a motorman as soon as he is out of sight, until he calls in from another telephone. The recently developed frequency-modelated radio phone which makes use of the trolleywire network in a mine as a carrying medium, permits instant and continuous contact between dispatcher and locomotives. The motorman can immediately contact another motor or the dispatcher regardless, of his motor's position on the trollywire system, whether moving or standing.

Meeting called to order at 11:30 A. M., February 23, by the President: Horace Moses, in the Chair. W. D. Brennan moved that the present Secretary continue, and he furnished an assistant. Before the question was put, he suggested that Frank Sandstrom, of the Colorado-New Mexico Coal Operators' Association, would be a satisfactory assistant, and his motion was extended to include the election of Frank Sandstrom as Corresponding Secretary, subject to confirmation after completion of reorganization, with the present Secretary as Executive Secretary, and that a Committee be appointed, one member from each of the four states, to devise and put into execution a permanent financing and operating policy for the Institute. Seconded and carried. The Chairman appointed W. D. Breunan, A. C. Watts, J. B. Marks, P. J. Quealy, with the President of the Institute as Ex-officio member and chairman.

The labor turn-over at coal mines has long been a fertile subject for parade by complaining coal operators, the question invariably occupying a place of prominence in the list of disabilities that tend to increase the cost of producing coal, adding likewise to the now startling number of accidents that occur in coal mines. This disability, however, is like the weather question, which some humorist once remarked of by saying, "The weather is something we all talk about, but nobody does anything to improve it." Endless compilations covering the shift of employment by coal mine labor have been made and published, and while the actual loss expressed in cents per ton in cost of coal produced has never been determined, the fact remains that such represents a substantial item, taking the mines of the country as a whole. Efficiency engineers who have made studies covering the cost of breaking in and training each new man employed in certain manufacturing industries, fix same as averaging not less than $100.00 per man, and when the character of mine employment is given due consideration, including its ever-present hazards, the difficulty of close personal super- vision of individual employes, and the, at times, almost impossible ability to transmit to men of many diverse nationalities understandable instructions, it is quite safe to say that the cost of securing and breaking in new men for underground mine work will fully equal that suffered by the factory managements. When we speak of mine labor turnover we must necessarily exclude the enforced shifting about of men who are laid off by the closure of mines due to accident or lack of market, con- fining ourselves to the turn-over occasioned by- (a) the dismissal of individual men or groups of men; (b) the voluntary resignation of the individual workman. It is these two methods of severance that the employer and employe alike suffer from; the item "Unclaimed Wages" carried in the accounts of every large coal company illustrative of the "quit this job, get another one" attitude of many workmen, who frequently, when leaving, fail to claim small sums due them, while others, in turn, leave a train of debts, large and small, behind. There is' ample evidence abroad to the effect that many

Today's coal market offers many unique buying and selling opportunities. By reviewing past and present marketing practices, new contracting philosophies can be developed with cooperation between the buyer and seller that can lead to a more stable market. This paper presents an analysis of the past and present coal markets and techniques that are currently being used in contracting that are intended to develop a more stable market place in the future.
