The opening session of the Forty-seventh Meeting of the Rocky Mountain Coal Mining Institute was called to order at 10:00 o'clock a.m., Thursday, June 7, 1951, in the junior Ballroom of the Hotel Utah, Salt Lake City, Utah, with President Arthur B. Foulger presiding. PRESIDENT FOULGER: We are a little bit late getting started, gentlemen. We have a few more members out there to register and we will wait just a few minutes until they are finished and then we will begin. The Honorable Earl J. Glade won't be here until 2:00 o'clock this afternoon. I understand lie was unavoidably detained so we are going to go down this program pretty rapidly when we get started, but we want to wait until those gentlemen still unregistered come in. Gentlemen, we will try and start now. Mr. Whiteside suggests that the minutes for last year probably should be read. However, they were published in the proceedings for last year, so I presume it will be just as well to dispense with the minutes and get going here before we lose too much time.

We all deplore the high accident rate of our coal mines, but when brought to task we immediately attempt to appease our conscience by calling attention to the high tonnage rate per fatality in American coal mines as compared to European mines, losing sight of the fact that the accident rate per hours of exposure has shown no improvement during the past twenty years. Measuring our accidents in terms of hours of exposure, not in terms of production, is the only correct method. Certainly it can be of only scant satisfaction to the miner to know that his chances of getting killed this year are as great, or perhaps greater, than last year, but the tonnage rate per fatality will have gone up. We cannot help asking ourselves why it is the other major industries, almost without exception, have made wonderful strides toward reducing accidents, while coal mining stands alone as the one major industry in which no improvement has been made. It certainly cannot be charged entirely to the increased use of machinery and the increased productivity per man employed, as the other industries likewise, or to an even greater extent, have increased the use of machinery and the production per man.

PRESIDENT SHOTT: Gentlemen, the meeting will now come to order, please. Members of the Institute: It is with great pleasure and honor that we welcome you to the thirty-ninth regular meeting of the Rocky Mountain Coal Mining Institute. I assure you that Mr. Krippner, the General Chairman, and his associates have an outstanding program in store for you, and trust it will be of much interest to the industry. I note by the program they have me slated for an opening address, but I am going to defer that, proceed with the remainder of the program, and endeavor to go on schedule and keep matters on schedule as outlined on our program. The first item on the program is the reading of the minutes of the thirty-eighth regular meeting by the Secretary. I might say that it has been customary in the past that we omit the reading of the minutes. If that is not agreeable, we will read them; otherwise, I would like for someone to make a motion that we dispense with the reading of the minutes, inasmuch as they are published in our annual report each year. What are your wishes?

Chairman Doc, distinguished guests, and fellow members of the Rocky Mountain Coal Mining Institute: It's a genuine pleasure to meet with you again at the 54th regular meeting. I might add that it is always pleasant to be at the top of the batting order. The field is wide open since there is no danger of repeating something already said. At the same time, I am aware that the lead-off speaker has a responsibility to avoid stepping on the toes of subsequent speakers. I promise to confine my remarks to areas other than those to be covered by the well qualified speakers that follow. During our meetings at this convention, many fine papers will be presented. Our thanks are due Bob Williams and his hard working program committee for the superior selling that brought so many eminent speakers to our meeting. And, of course, our special thanks go to Doc Schloss, general chairman of this meeting. Doc and his able colleague, Stan Shubart, have been the spark plugs that fired up all of the arrangements we are enjoying here in Glenwood Springs. I'm sure all of us are appreciative of the many hours Doc has devoted to seeing that our meetings will be pleasant and profitable. When we mention arrangements, we always think of that master arranger, Fred Whiteside, who, as a charter member and secretary-treasurer of the Rocky Mountain Coal Mining Institute, has had more to do with more matters around these parts than just about anyone I can think of.

Session 1 - 1 :45 p.m. June 27,1983 Session Chairman: Robert Diederich, RMCMl New Mexico Vice President MR. DIEDERICH: My name is Bob Diederich. I'm the Vice President of the Rocky Mountain Coal Mining Insitute from the state of New Mexico. I'm manager for the Navajo Mine down in Farmington, New Mexico and also project manager for a new mine that we're starling out called the LaPlata Mine in the same area. I'd like to introduce our first speaker, Tom Lien, who is the Director of Engineering, Western Division of AMAX Coal Company. He is responsible for mine engineering, environmental engineering, permitting, reclamation, planning, design and construction plant engineering, geology exploration, quality control and real estate for the western division. He joined AMAX Coal in 1980 as manager of preparation and quality control and was promoted to the present position in August of 1980. He has a BS in geological engineering from the University of Mines. He previously worked for Kennecott Copper Corporation in Hayden, Arizona from 1965 to 1970. He worked as a mine geologist, mill metallurgist, mine production and quality control engineer. Then he also worked for Kaiser Steel Corporation, Eagle Mountain Iron Ore Mine in California, 1970 to 1977. Worked as a process engineer and plant superintendent at that place. Then he was employed by Mountain States Research and Development, Tucson, Arizona, 1977 to 1980. Worked as a senior process engineer and operation superintendent. So without further ado, I'd like to introduce Tom Lien who will talk to us about in-pit coal crushing. MR. LIEN: Thank you. The official title of my paper is actually: "The Potential for In-pit Crushing and Conveying in the Powder River Basin." The Powder River Basin is one of the world's greatest coal fields and will be an important source of energy for centuries to come. About one-eighth of the total coal producing in the United States comes from the Powder River Basin, and 80% of that production came out of Campbell County, Wyoming last year. The growth potential for this region is projected to be enormous. New technology as well as existing technology will make this region competitive in the decades ahead. Understanding the current status of the Powder River Basin, both the mines and the possible methods for changing the means of material movements within the mines is the subject of this paper. Each mine is unique and must be addressed specifically with respect to the application of new and innovative technology. There have been many articles written in the recent mining journals on in-pit crushing and conveying applications, including costs which are very interesting, enlightening and I recommend it to any company considering such installations. To give a general setting, coal production in the United States for 1982 was about 800,000.000 tons. This production came principally from six regions, the Applachian fields of the eastern states where bituminous and anthracite coals have been mined for almost three centuries, the Midwest located in the upper Mississippi Valley are often typified by huge dragline operations of which AMAX Coal has three right now, the Gulf Coast lignites. feeding mine-mouth power plants, the vast bituminous and sub-bituminous departments of the four-comer states of Arizona, New Mexico, Colorado, and Utah and finally the Northern Great Plains lignite fields currently being developed and the sub-bituminous fields of Wyoming and Montana including the Powder River Basin. The Powder River Basin is located in northeastern Wyoming and southeastern Montana. It is the darker brown right in the center of the photograph. It covers about 18,000 square miles. It's about 200 miles north to south and 90 miles east to west. The shallowest coal beds are on the east, north and northwest edges of the basin with deeper coal beds toward the center in the same kind of relationship. There are about one trillion tons of coal in the Powder River Basin, that's the one with 12 zeros after it. A little bit there. It's distributed in many, many seams at varying depths to the current topography. In 1982 about 100,000,000 tons of coal were mined from this basin and 81,000,000 tons came out of Campbell County, Wyoming. The mines that are shown in this picture are basically the mines around the basin edge. The principal area that I'll be talking about is the eastern edge down where it shows Gillette and Campbell County. Geologically the Powder River Basin is the Fort Union formation. The most productive seam is called the Wyodak or Smith-Roland or the Anderson-Canyon, depending upon where you're located. There is about 75 billion tons of coal in the Wyodak of which about 23 billion are considered surface minable today. the coal is Paleocene in age, about 40,000,000 years old. It was once an old Delta region very much like the Mississippi River delta is today. During the 100,000 years that this deposit was formed peat accumulated to a thickness of about 365 feet. It was later buried and turned into sub-bituminous coal. All of the coal mined in the basin is for the electric utility industry. This coal has a typical BTU content of about 8,300 plus or minus about 4,500 BTUs. Sulfur coal is generally less than'/ %, thereby making this coal compliance coal in terms of sulfur dioxide emissions, 1.2 pounds of sulfur dioxide per million

Ladies and Gentlemen: At the request of Mr. J. M. Jennings, chairman of the General Committee on arrangements during the convention of the Rocky Mountain Coal Mining Institute here, I have endeavored to prepare a brief description of the Columbia Steel Corporation's tipple at Columbia, Utah, and its operations, but [ ] from the fact that you have already listened to, and have been interested I'm sure, in the description given by Mr. Jennings and Mr. Murphy, on tipple construction and operations, I am taking the liberty, with your permission, to embody in my paper a description of our haulage and ventilation systems at Columbia, which I hope will be, in a measure, also interesting to you. As many of you know, we are mining on a Multiple Panel System, which while comparatively new in Carbon County, is being used successfully in various mining districts of the United States. Mine The Columbia mine is situated about four miles south of Sunnyside, Utah, at an elevation of 6,760 feet at the portal or main entrance of mine. [ ] From this portal, the main air intake or solid rock tunnel, about 1,600 feet long, runs into the mountain in an easterly direction to an intersection of the coal vein on a grade of 0.5 of one per cent in favor of the loads. There this main entry divides and forms two main entries. These are run in parallel with 100-foot chain pillars between them and protected with 150-foot barrier pillars on each side, and run into the coal in a southerly direction on a 0.5 of one per cent grade in favor of the loads for a dis-
