Briefly, the machine consists of a steel frame mounted on roller bearing wheels and axles, an electric motor, a fully enclosed speed reduction gear unit, a specially designed centrifugal pump driven through a friction clutch and silent chain, a mixture tank and agitators, and all necessary operating and control mechanism. The wheels are mounted on solid roller bearings made of special roller bearing steel, and are cast with deep chilled threads. The axles are of high carbon axle steel. A General Electric Company motor, of special design to exclude dirt and moisture, is used. It has an unusual overload capacity and a maximum torque at starting speed. Special arrangement can be also made for storage battery operation. The motor drives from one end, through a flexible coupling, to the speed reduction unit, and from the opposite end, through a similar coupling, to the pump clutch. The design of the flexible couplings is such that the drive is reversible. The speed reduction gears are enclosed in an oil and dust proof housing. All spur gears, as well as the main drive clutch, are made of steel forgings, with accurately cut teeth. An aluminum bronze worm wheel and special heat treated alloy steel worm provide the speed reduction for the traction drive. The worm shaft is mounted on Hyatt roller bearings and the thrust is taken in each direction by ball thrust bearings. The main drive shafts are of special alloy steel and operate in Hyatt roller bearings. The slow speed shafts run in extra large bronze bushings. Ample and constant lubrication is provided by splash from the gears running in oil. The Mudite pump is of special de- sign. A renewable wearing plate protects the pump casing from the natural wear of the mixture. The open runner is mounted on an extra large shaft which runs in a Hyatt roller bearing on the pump end and in Timken roller bearings on the outboard end. A special cage prevents water and grit from reaching the pump bearing. All thrust from the runner is taken on the Tim- ken bearings and these bearings also provide for the accurate and easy adjustment of the runner. The pump is driven by a silent chain, which operates on cut steel sprockets, from a friction clutch. The clutch is designed to secure long wearing qualities with minimum attention and its adjustment is easily effected. It is mounted on Hyatt roller bearings and the clutch drive shaft also runs in the same type of bearings. The pump discharges through a nozzle, which is adjustable, and controlled by the operator. The mixture tank is of approximately 650 gallons capacity. It is provided with a mixing well constructed of perforated plate screen to prevent large hard particles from getting into the valve or pump. The tank is filled through an opening in the top directly into the mixing well. On a shaft running longitudinally through the tank are arms so arranged that the mixture is thoroughly mixed and kept in continuous circulation from end to end. This shaft is driven from the speed reduction unit by a steel roller chain operating on cut sprockets. The traction drive is taken from the worm wheel shaft through steel roller chains of extra large size that run on cut steel split sprockets on both axles. An idler sprocket provides for easy chain adjustment. The axles are mounted in solid roller bearings in fully-enclosed dust proof housings, which support the frame through coil springs. These springs eliminate twisting strains on the frame on account of track irregularities and also relieve the working mechanism from road shocks. The speed reduction from the motor to the wheels is such that it gives an operating speed of approximately ninety to one hundred thirty feet per minute. The brakes are of the conventional shoe type and engage the wheels on both axles. They are operated by a hand wheel conveniently located and

By J. L. Floyd

The Trapper Mine is a large surface coal operation located in northwestern Colorado US. The coal seams at the mine dip an average of 8 degrees so, historically, their dragline pits have been orien-tated parallel to the dip of the coal seam to balance stripping ratios. However, the mine plan in the future G and Z pits is designed to take advantage of pit orientations that are parallel to the strike of the coal. During the initial presplit and cast blasts in G pit, significant slope damage occurred. This damage included the opening of joints and tension cracking. There was also block movement directly above the L coal seam, which is the main plane of weakness in the slope. A detailed site evaluation was conducted to develop specific blast design modifications to protect the slopes during future blasting. The modified de-signs successfully controlled vibration levels during the blasting of the Z pit box cut. This paper includes a review of the blast vibration related factors that influence slope stability along with a detailed discussion of the field tests and design modifications developed.

The first Mine Rescue Performance Evaluation for mine rescue teams was held just prior to the 1992 RMCMI convention meeting schedule on June 27 and 28. Six teams took part in this year's evaluation; Decker Coal, Decker, Montana; BHP Minerals' White Team and BHP Minerals' Purple Team, both of Aztec, New Mexico; Kerr McGee Coal Corporation, Jacob's Ranch Mine, Gillette, Wyoming; The Coteau Properties Company, Freedom Mine, Beulah, North Dakota and The Falkirk Mining Company, Falkirk Mine, Underwood, North Dakota. This was the first mine rescue evaluation program developed to measure a unit's proficiency in their skills rather than emphasis on a ranking order of teams. The objectives for the evaluation were to promote learning and to evaluate the current level of experience of the attending rescue units. The priority goal for this evaluation was to recognize current rescue skills, knowledge and abilities of each team participating. In doing this, each team is provided with individual evaluations and a path for improvement as needed. [ ] Realistic industrial related scenarios, closely simulating the stress of actual rescue incidents, was provided by members of the Hermosa Cliffs Colorado Fire Department under the direction of Dan Noonan, Fire Chief. On Saturday, June 27, five rescue scenarios were presented for each team to complete and on Sunday three of a more difficult nature were encountered by each team. On the final day of the RMCMI convention two of the teams performed rescue demonstra¬tions. Onlookers were afforded the opportunity to view the teams in action as they simulated actual rescue operations. The value and importance of mine rescue teams such as those participating in this year's Rescue Team Performance Evaluation are very evident as in many cases they are the only rescue personnel and medical staff on the work site in case of an emergency. Most of these persons are volunteers who spend many hours studying, practicing and perfecting their expertise in the lifesaving techniques needed in the event of a mine emergency. At the same time, they are very qualified coal miners who perform their respective duties at their mine locations, Their dedication to gaining the most knowledge they can get to handle these life and death situations is evident in their participation in evaluations such as this one. [ ] If a highly educational, informative, sharing of knowledge and expertise, while at the same time providing a very enjoyable experience, deems this evaluation a success ... the Rescue Team Performance Evaluation held during the RMCMI Convention at Tamarron this year was certainly a SUCCESS!! It is hoped that you can all enjoy this same experience with us next year! Linda G. Ash The Falkirk Mining Company [ ]
