"Finance Minister Donald Macdonald's budget of May 25, 1976 featured a restructuring of the anti-inflation profit controls and a grab bag of tax changes, some of direct interest to the mining industry. All Canadian taxpayers now will be permitted to write off immediately 100% of mineral and oil and gas exploration expenses included after• May 25, 1976 and before July 1 1979. The cost of acquitting Canadian resource property after May 6, 197.4 from a federal or provincial government will now clearly be included in Canadian development expense, and provincial drilling and exploration incentives received after May 25, 1976 will not reduce exploration and development expense for federal income tax purposes. Under tough new anti-inflation profit controls, all controlled businesses, except distributions, will essentially have one uniform set of rules for• determining allowable profit margins; this allowable margin will be determined by product line or by over-all net margin and will be 85% of the higher of the margin obtained in the five years preceding October• 13, 1975 or the one year preceding May 1, 1976. The basic capital cost allowance system is to continue, but many rates will be revised. The ability to offset losses created through claiming capital cost allowances on leased equipment, etc. against other income will be ended with respect to transactions entered into a/te1• budget night. Miscellaneous other tax changes will raise the low rate base for Canadian-controlled private corporations to $750,000 increase retitement plan contribution limits and reduce the rate of branch tax imposed on branches of corporations resident in a country with which Canada has a comprehensive tax treaty to equal the withholding tax rate on dividends under that treaty."

In his March 31, 1977 budget, Finance Minister Macdonald has attempted the delicate balancing act of stimulating the economy without reinforcing the inflationary pressures which Canada is continuing to experience. Several tax changes of benefit to the mining industry, as well as measures designed to encourage oil exploration in frontier areas, are among the budget proposals. Additional earned depletion of 66- 2 /3 %, which may be offset against income from any source, will be available on drilling costs in excess of $5 million incurred between March 31, 1977 and April 1, 1980 in connection with an exploratory well in Canada, including the continental shelf . Other changes include more favourable treatment of resource property dispositions, less restrictive rules r elating to "successor corporations" , increased capital-cost allowance on railway spur lines, the inclusion of certain production royalties in Canadian development expenses and the application of the lower "manufacturing and processing" tax rate to sulphur production. To encourage business capital spending, the 5% federal investment tax credit it to be extended an additional three years to mid 1980 and broadened to include spending on scientific research and development. The rate of credit will also be selectively increased on a regional basis, to 7.5 % in certain designated areas in Saskatchewan, Manitoba. Northern. Ontario and Quebec, and to 10% in the Atlantic provinces and the Gaspe.

In the spring of 1977, Revenue Canada announced its intention to proceed in 1978 with a plan to impute a taxable benefit on interest-free and low-interest loans provided to employees. Such loan arrangements are often an important aspect of the compensation packages provided by many companies to their employees. Since the original announcement, there have been many submissions to Revenue Canada opposing this change, and the Finance Minister has now brought down a compromise solution with the introduction of a proposed amendment to the Income Tax Act. The amendment, which would not take effect until the 1979 taxation year, would require an employee, a shareholder or a related person to include a benefit in income measured as the difference between the interest on any such loan computed at bank prime rate and any interest actually paid. Only the amount of such a benefit in excess of $500 in a particular year would be required to be included in income. Of particular interest is the exclusion from these benefit rules of loans up to $50,000 in respect of the purchase of a house on the relocation of an employee and loans provided for the purchase of shares of an employer corporation.

In his Budget Speech on March 31, 1 977, the Honourable Donald S. Macdonald expressed concern about the financing of investments through new equity issues. He mentioned the need to render more attractive participation in the equity market by investors in all in come brackets. One of the measures introduced in the budget to accomplish this goal is the proposal to increase the dividend gross-up and tax credit in respect of most dividends received by an individual from Canadian companies. The following comments and tables serve to illustrate the impact of this particular proposal.

For the sixth year in a row, the value of nonfuel mineral raw materials produced in the United States set a new record, reaching almost $17 billion in 1977. Data provided by the Bureau of Mines show that the 1977 value of domestic nonfuel mineral production exceeded the 1976 value, $16.7 billion, by 2 percent. The $17 billion worth of minerals was the basis for approximately $770 bill ion worth of processed materials of mineral origin. Output of metals decreased $360 mil lion in 1977, while that of nonmetals increased $670 million. Of the 22 metals produced, output of 12 increased, and the value of 13 increased. Among the 46 nonmetallic minerals produced, the quantity of 27 increased, and the value of 34 increased.

Industrial minerals enjoyed a fairly successful year in 1978, despite the sluggish economy, inflation, and environmental restrictions. A glance at US Bureau of Mines statistics shows that, in general, production of industrial minerals increased from + 1% (salt) to as much as 26% (sulfur, other than Frasch or recovered). A few industrial minerals showed a decline; fluorspar production, for example, registered a 23% decrease in 1978 from 1977 due to the closing of three domestic mines. Bromine, natural sodium sulfate, Frasch sulfur, and vermiculite also had production decreases of 2-6% in 1978.

Escalating energy costs and tough environmental standards were two major factors affecting the minerals processing area in 1978 For the most part, new startups and research and development initiatives were directed toward improving process dynamics, investigating alternative processing strategy, and lowering unit costs. In the flotation area, the trend to larger machines continued. Scientific investigation of the modeling and process control of flotation was apparent, as was the research and development of new flotation reagents.

For the seventh consecutive year, the value of nonfuel mineral raw ma¬terials produced in the US set a new record, reaching almost $20 billion-up 12.7% from the previous year, according to the US Bureau of Mines. The Bureau reported that this mineral production was the basis for about $200 billion worth of processed materials of mineral origin.

Jan 5, 1979

The value of raw nonfuel mineral materials production totaled an estimated $19.7 billion in 1978. The record 1978 value exceeded by 13 percent the 1977 value of $17.5 billion. This raw mineral output was the basis for approximately $200 billion worth of processed materials of mineral origin. Output of both metals and nonmetals increased about $1 billion each, above comparable figures for 1977. Of the 22 metals produced quantitative output of 11 increased and the value of 13 increased. Among the 48 nonmetallic commodities produced, the quantities for 35 increased, and the values for 40 increased.

There is a saying, the greater the gratitude, the shorter the speech. That puts me in a quandary, because while I am grateful for the honor you do me today, I also want to talk about a subject very important to all of us. A few months ago, when I was asked to submit a title for my talk, I chose "Quality where it counts." I did so because perhaps the most important thing we at Amax did in our restructuring was to commit to quality in all our businesses - quality people, assets, and operations. Together, they create quality performance, which produces quality growth and increased shareholder value - our prime corporate mission. We are dedicated to quality. At Amax, quality means everything. Today, I want to discuss quality in another context - the need for it in American education and what we have to do to achieve it. If we ignore this need, we will all suffer the consequences. And they will be upon us far sooner than the next century, barely a decade away. I think almost everyone in this room works for an organization that had to restructure in the 1980s. Mining companies that did not, just didn't make it. Well, we did. As an industry, we are seeing improved profits, positive cash flow, and a more competitive position in the world marketplace. But all the restructuring we have done, all the hard work, and all the pain that was part of it, will be in vain if, down the road, we do not have the educated people we need as workers. We need them to design, manufacture, and market the products that use the basic materials produced by the mining industry. Simply put, we are at a crisis point in education today. That is no new revelation. Nearly six years ago, the National Committee on Excellence in Education published its report, "A Nation At Risk." Since then, things have not gotten better. The Wall Street Journal, Business Week, US News & World Report, and Fortune have all recently published stories about the sorry state of education in the United States. The subject has become the topic of TV talk shows as well as national commissions, and for good reason. The pool of young people entering the US labor force is dwindling. In the next decade, 10 million fewer will enter the job market compared to the 1970s. But fewer of them will be qualified to do the jobs available to them. Here's why: • 20% of today's high school students drop out before they are 18 and another 20% graduate functionally illiterate; 40% of today's fourth graders think the world is flat; • 20% of today's sixth graders cannot locate the United States on a world map; • one of every three ninth graders cannot figure the change for a two-item meal - and I'm talking about a Big Mac and fries. These are not just problems of minority kids in big city ghettos. Fully 40% of all young working Americans cannot add up their lunch bill. Three out of every five college freshmen need some kind of remedial work. These statistics are frightening. Particularly so because, while the work force is becoming less qualified and our public education system is getting worse, our products and technologies are becoming more complex. We are approaching a time when we will have machines that recognize handwriting but people who cannot write. We will have technology to take voice commands, but people who do not know what they are talking about. The accelerating pace of technology is changing the nature of the job market. The fastest growing jobs now, and in the years ahead, are in professional, technical, and sales positions requiring the highest education and skill levels. Most of these jobs will require the use of a computer. Yet, 95% of today's graduating high school students have never laid a finger on a computer keyboard. While our education system is failing the students it is supposed to serve, other countries are doing far better. In a

In overview, the world's mineral industry in 1989 registered gains over its 1988 performance, but these gains were by no means as pronounced as had been those of 1988. The traditional statistical measures of mineral industry performance, namely production, trade, and consumption levels, reflected significant growth in most industry sectors from crude material extraction through the gamut of down- stream processing. Growth in market economy countries generally exceeded growth in the centrally planned economy countries as a result of a variety of causes that will be covered subsequently, but even among the centrally planned countries there were some upturns. In contrast to these measures of the soundness of the industry, the situation for nonfuel mineral and metal prices was less satisfactory than in 1988, and low crude oil prices continued as a problem for the all-important petroleum sector, despite some gains during the year. The oil price situation mitigated against price increases for competitive fuels. Although this was unfavorable for fuel producers, it remained advantageous to consumers, including nonfuel mineral producers, processors, and transporters. Thus it cannot be viewed as a negative factor for the whole of the global mineral industry. Global crude mineral output value was estimated at nearly $1,420 billion in current dollars, an increase of 9% over the 1988 level, and an increase in current dollar terms for the seventh consecutive year. Measured in terms of constant dollars, however, adjusting for inflation, the increase was only 4.7% compared with the 1988 level. Despite the prolonged growth trend, the 1989 crude mineral output value level was still 3.2% below the record high set in 1980, which was $1,467 billion in terms of 1989 dollars.

To concede that I am the most surprised - not to mention the least likely - recipient of the Daniel C. Jackling Award is a true confession I must share with you. Quite honestly, I've asked myself, "Why me?" The Jackling Award has a well-deserved reputation of being a practitioner's, a doer's, a CEO's award - not kudos for a retired school teacher! While at least five of the previous recipients have taught in universities, to my knowledge I am the first to earn the award for "alleged" academic accomplishments. It is humbling enough to keep me livable for a long time. If you glance over the roster of Jackling Award lecture topics, you will spot another anomaly: The lectures last year and this deal with the subject of education - the only two in the 37-year history of the award. The two complement one another rather well, too, C. Allen Bom of Amax addressing critical needs of public education, while I am going to look at the post-high-school years. But I want to focus on more than engineering education. The training role of industry - the principal consumer of our product-also warrants examination. As I hope to establish, there is something unique about mining engineering - education and practice - that is both strength and weakness. We need to recognize that, if we are to cope with the weaknesses in order to capitalize on the strengths. We look at five premises that relate to the uniqueness of the mining engineer and his or her preparation for a professional career.

In broadest overview, a substantial part of the world's mineral industry in 1990 registered small gains over its 1989 performance, but traditional statistical measures of mineral industry performance, namely global production, trade, and consumption levels, failed to mirror these gains. This was because of the sharp downturns in the mineral industry activity in the U.S.S.R. and the former centrally planned economy nations of eastern Europe. These downturns in this one geographic area had influences on almost all traditional statistical series, in some cases simply significantly reducing growth, in other cases providing for a global downturn, in almost all cases despite considerably brighter outlooks based on activities in other world areas. To be sure, the U.S.S.R. and eastern Europe were not the only places on the planet suffering problems of one type or another in 1990 that impacted on minerals industry activity, but with the acquisition of information presently available, it seemed almost assured that the difficulties of these economies in transition will be the most difficult of problems to resolve in the long run. It certainly appeared that the legacy of the half century or more of economic central planning will be a decade or more of very difficult adjustments, and a number of these will greatly affect not only the minerals industry of these transition countries, but also the rest of the globe's mineral industry as well.

I am indeed honored to be the 1991 recipient of the Daniel C. Jackling Award. To be voted this honor by my peers in the Society for Mining, Metallurgy, and Exploration and AIME means more to me than I can truly express. Daniel Jackling's position and prominence in the mining industry first came to my attention in the fall of 1949 when I transferred from Wisconsin Institute of Technology, then a three-year school, to the Missouri School of Mines to complete my last year for a bachelor's degree in mining engineering. I played basketball in the Jackling gym and ran track on the Jackling field. I didn't know a lot about Jackling then, except he was an honored graduate of the school and, obviously, supported the school financially. Over the years, Jackling's name kept coming up. He was a man with a reputation for being a doer, a mining leader who was always a step ahead, a mining engineer who knew how to motivate men in the working place, to organize mining systems, to finance and organize corporations. to open up new, low-grade ore bodies for exploitation. If Jackling were alive today, I would expect he would bean excellent candidate to apply practical rock mechanics to his projects. Looking over the list of Jackling Award recipients, I have known many, have met many personally and had a few who were dear friends that affected my own professional life. Ab Shoemaker, '58, and I consulted at the White Pine Copper Co. on mining problems in the 1960s. We arranged for our visits to the mine to coincide so that we could collaborate on our ideas. I would rent an auto and drive for Ab. He said he was the only mining engineer in the country that had a PhD for a chauffeur. James Boyd, '67, was my mentor as regards the White Pine Rock Mechanics Program that we organized in 1963. Only through Boyd's forsight. leadership, dedication and willingness to spend money on research and development did the Practical Rock Mechnics Program at White Pine succeed. He never wavered in his support to that program or to me personally. Tom Howard, '75, was my predecessor in 1970 as Director of Mining Research for the US Bureau of Mines. When I joined the Bureau in August 1970, he had the research centers up and running. Any successes I may have had with the Bureau of Mines were due in great part to Tom's leadership and organization throughout the 1960s. Gene Cameron, '68, was my teacher at the University of Wisconsin and I remember him fondly. He was the one professor who lectured in a manner that made me welcome going to his classes each day, a truly remarkable educator. If you have come today to listen to me talk about instrumentation, rock properties, stress-strain relationships, rock mechanics theory, etc., you will be disappointed. Large volumes of data have been collected by well qualified theoreticians to define stress-strain conditions in mines. Unfortunately, very little of this data has been used by industry due to the lack of initiative and understanding by the researchers to the true problems of implementation in the industry. I hope my remarks will assist future investigators to work through the maze of operational problems so they will experience the satisfaction of seeing their research used. I fully realize that the Jackling Award is given by the Society for Mining, Metallurgy, and Exploration and is primarily offered for accomplishments in hardrock mining. I have found it impossible to separate hardrock and coal mining when I talk about "Applied Rock Mechanics." There is too much overlap and the same mechanics principles are applied to both. For example, coal mine designs have been applied to salt, trona and potash. Also, the original layout and design of White Pine Copper Mine was based on coal mine designs. Any developments to apply rock mechanics ideas must

This paper is based on field studies in North American surface mines. The work involved the adaptation of microprocessor-based instrumentation to monitor various operating parameters on-board rotary blasthole drills and mining shovels. Following a review of instrumentation and monitoring methodology - drawing on experience gained under field conditions-the paper will focus on the application of monitoring technology within the framework of an Integrated Equipment Monitoring System. Such a system will permit real-time performance evaluation of key equipment involved in surface mine production. Drill performance monitoring has been demonstrated through work to date, to provide significant input into blast design, reserve estimation, mine planning and production control processes, through an improved facility for ground characterization. Monitoring excavation equipment has been proven valuable in assessing how effectively the input from drill monitored data has been used in the evolution of blast designs. This specifically refers to assessing blast efficiency through measuring associated levels of excavator performance in relation to muckpile characteristics. The medium-term goal of equipment instrumentation and monitoring has been to assist mines in optimizing the overall rock breakage and handling process. Based on the reported results, this has been accomplished. Long-term efforts now concern using a greater understanding of equipment performance and response to varying operating conditions as a foundation for the implementation of mining automation.
