Thank you for inviting me to come here and be your keynote speaker. Texas also thanks you for being included as part of the Rocky Mountain Coal Mining Institute. We'll kind of think of Texas as Baja Rocky Mountains. I've always wondered why coal miners were the only people to go to the mountains in the summer time-and now I know why. The program committee should be given a big hand for selecting this RESORT. And the golf course is stimulating to say the least. This is a very beautiful location. I was asked to talk about CHALLENGES, OPPORTUNITIES and INNOVATIONS as they affect the coal industry. I am going to do that from a Texas perspective. But first, since Texas is the newest state to belong to the Institute, I would like to give you a little background on how our coal industry got started and where we are at today. The vast majority of our coal is called lignite-it has a little lower heating value than most other coals and ranks somewhere between buffalo chips and sub- bituminous. Lignite is found In three geological formations running Northeast to Southwest through South and East Texas. In-place reserves lying within 200 ft. of the surface total 14 billion tons. This slide shows the lignite formations with cur- rent mine operations colored in RED. Mines that are planned to be built in the next 10 years are shown in BLUE. Lignite was used mostly by settlers in Texas during the 1800s. It was used as a fuel to fire locomotives during the Civil War. Between 1900-1930, about 100 mines, mostly underground, were operating in Texas producing lignite for home heating and as a boiler fuel. Here are some slides showing underground access, [lie tipple used to process the lignite, and the underground workings. This is the "BIG LUMP COAL COMPANY" as shown here. The typical underground mine was 100-150 ft. deep and each miner produced 7-10 tons per day-all by hand. In 1926, the Texas Power & Light Company built the Trinidad Power Plant and began using lignite as a boiler fuel. The lignite was mined by the McAlester Fuel Company at the nearby Malakoff Mine. Here are some slides showing a stripping shovel at Malakoff uncovering lignite. The lignite was loaded into railcars in the pit for transport to the power plant. This is a picture of the Trinidad Plant which had two 20 MW units and one 32 MW unit. At the time, Trinidad was the largest power plant in the United States using lignite exclusively as a fuel. Trinidad operated until 1942 when it was converted to natural gas that was sold to the plant for 3 ½ ¢ per MMBT'U. The mine closed after having produced 7 million tons. Lignite was mostly forgotten about until 1953 when Alcoa started an aluminum smelter. Our Company formed a subsidiary called Industrial Generating Company to operate the power plant that furnished electricity to the smelter. We also operated the nearby Sandow Mine that supplied lignite as a fuel to the power plant

The first session of the Rocky Mountain Coal Mining Institute was called to order by John T. Maulsby, Superintendent of Maintenance and Planning, Columbia-Geneva Steel Division, U. S. Steel Corporation, Dragerton, Utah, representing the past-president. W. K. Dennison, Jr., Superintendent. Koehler line. Kaiser Steel Corporation. Raton, New Mexico, who was unable to attend. Mr. Maulsby welcomed the members and guests, and introduced the President, A. Z. Dimitroff, Mining Electrical Engineer, Health and Safety, District 1-L, U. S. Bureau of Mines. Denver. Colorado. The text of President Dimitroff's address of welcome is as follows: The President's Remarks Guests and Members of the Rocky Mountain Coal Mining Institute: The distinct honor and privilege of officially welcoming you to this, the fifty-seventh regular meeting of the Institute, is indeed a pleasure. Your officers and committees have tried to provide a varied program which I am sure should have something of interest to all of us. The theme of this meeting, "Where Do We Go From here'?", appeared rather fitting for the In¬stitute this year because, as most of you know, until only two weeks ago we thought that this is the last time we will be able to meet at the Colorado Hotel, which has been the favorite spot of most members. Your officers and many of you were literally asking just that question.

The 81 st Regular Meeting and convention was called to order by the President, Charles W. Margolf at 9:00 a.m. Monday, July l, 1985 in the Silverton Room of Tamarron, a resort hotel near Durango, Colorado. President Margolf welcomed the members and others in attendance to the convention and noted his theme of "Make It Happen!" He introduced those present of the 1985-86 Board of Directors and Officers who were elected by the Board of Directors at their Annual Meeting June 29. They were: Arthur K. Neill, President; Bernard Bernstrom, President-Elect; Loren V. Linville, Convention Liaison Officer; Vice Presidents Douglas J. Hammer of Colorado, C. Joe Presley of Montana, Alva L. Smith of New Mexico, Fred Wertz of North Dakota, Rex Berry of Utah and Thomas J. Lien of Wyoming; and Doris G. Finnie, Executive Secretary & Treasurer. He also introduced Ira. E. McKeever who was elected to serve as chairman of the Advisory Board by that group. Margolf mentioned that one three-year term as a Director would be voted upon at the annual business meeting which would be held Tuesday, July 2 at 1:30 p.m. in the Windom Peak Room and introduced James "Doug" Ingram, the nominee of the Nominating Committee. A convention update was made by the Conven-

PRESIDENT WHITESIDE: The chair will now throw the meeting open to discussion. GEO. B. PRYDE: In the old days at Rock Springs we had electric plants situated about half a mile from our mines; we had small boiler plants; we had an electric plant with about 600 kilowatt capacity. About ten years ago we discarded the old steam plants and started building towards a centralized power plant. We now have three 2,500-kilowatt turbine generators and one 1,000, and our peak load is about 7,000 kilowatts. We have had to rebuild the old power plant, scrap the old machines, and install water tube boilers. We did this as a matter of economy in a small local plant we had years ago, and it has grown to be a large central plant, supplying power for about 20,000 tons of coal daily, and distributing this power within a radius of twenty miles. We have found this method of power to be more economical than with the old plants, and the people who buy power from us in the Rock Springs field say it has been to their advantage also. We found this last year, when we had to shut down for five months, that that plant was the only plant operating in the Rock Springs field, supplying all the power, running of fans and pumping during the time the mines were shut down, and it helped the situation very much. We had an old wooden building which we had to tear down, raise the walls, and put on a steel roof; had to rebuild the boiler room and rebuild the boilers. The water situation at Rock Springs has never been very good; we get our water from wells 250 to 500 feet deep, and use one and one-quarter million gallons a week. We have two large spray ponds and we have gotten along well. There isn't any comparison between the central power station and the old method of making power. (Applause.) FRANK YOUNG: I listened with a great deal of pleasure to the paper just read, and it struck me it was remarkable how a paper prepared by anyone could be so nearly identical and coincide so very near with the experience of another. It is just like some work I have had. I had the engineering part to do for the power plant for ten years, and I think at that time we did all of the things that he mentioned in his paper. Also his analysis of the cost of power seems to me exactly right. If I had gathered the figures and made the statement myself I think it would have been very much the same as was read. The recommendation that it is better to buy

The Sixty-First Regular Meeting of the Rocky Mountain Coal Mining Institute convening at the Stanley Hotel in Estes Park, Colorado, was declared in session at 10:00 a.m. by Past President Claude P. Heiner, President, Minerals Development Corporation, Salt Lake City, Utah. Claude introduced Oren F. Bridwell, Secretary, Northern Colorado Coals, Inc., Denver, Colorado. His introduction of President Bridwell follows: Ladies and gentlemen, it is my privilege and pleasure to open this session of the Sixty-first Regular Meeting of the Rocky Mountain Coal Mining Institute. My particular assignment is to introduce to you (those of you at least who do not know him) our Acting President, who for now we will call "Brid."

Good Morning. Thank you for your kind welcome, Lyle and thank you for having me here today. I spoke at the fall meeting of the Utah state RMCMI in Price and it's nice to be invited back. I can see by the program that you have two great days of interesting and informative meetings, including the mine rescue team exhibition and the safety recognition award presentations. As you all know, I am here standing in for Dave Lauriski, who is in China with Secretary of Labor Chao. As you also know, Utah is near and dear to his heart - and so is the Rocky Mountain Coal Mining Institute. I want to assure you Dave would be here if it were at all possible. But it is my good fortune that I could come in his place. We have made great progress as an Agency thanks to the hard work and dedication of MSHA's employees. But we are always looking for new ways to solve problems and continue to send more miners home safe and healthy every day. And we have been working on some great ways to do that, including thinking strategically. During my presentation today I'm going to talk about where the Agency is in terms of our transformation to the MSHA of the 21st century, a little bit about how we got to be where we are, and then describe our roadmap to the future state. And I'm going to focus on the significance of our plan and the planning process to demonstrate the implication for the mining industry. Former President Dwight Eisenhower once said, "In preparing for battle I have always found that plans are useless, but planning is indispensable." Now I do like Ike, but I would have to take exception to the first part of the sentence. I have found plans and the planning process to be indispensable - the plan to give me a roadmap to my goal, and the process to focus me on the steps I must take to get there. We all know that having a strategic plan makes the difference between success and failure. We've seen it time and time again, in business, in our lives - and in government: Having a strategic plan is crucial to success. And the process of making the strategic plan is crucial to its success. Putting together a workable strategic plan - a good roadmap - that will successfully lead you to your goals requires a thorough, careful process that takes into account each factor that you may encounter along your way to success, as well as those with whom you will travel. In order to talk about our current plan I want to take you back to three years ago, when Dave Lauriski went to Washington to lead MSHA. He knew that change was in the air. Dave was confirmed as Assistant Secretary with 30-plus years experience in the coal mining industry, and more than 20 years of experience in dealing with

Past President Ralph Moore opended the meeting at 9:30 a.m. He thanked all the committees for their part in making the 1977 meeting the success is was. He then turned the meeting over to President-elect, Shirl McArthur. President McArthur called on the Auditing Committee to present its report. Gabe Ishley, Chairman, read the report and asked that it be approved. A motion was made, seconded and carried. Loren Linville gave his report on registration and new members which figures are in the Monday a.m. business meeting of the Proceedings. The Resolutions Committee was asked to give its report. William Bear, Chairman, submitted the following: (1) RESOLVED: WHEREAS, in the year since the last convention of The Rocky Mountain Coal Mining Institute, the Institute and the coal mining industry have suffered the loss through death of the services of: John A.

The Third Session of the Forty-Sixth Meeting of the Rocky Mountain Coal Mining Institute convened at the Hotel Colorado, Glenwood Springs, Colorado, June' 20, 1950, at 9:30 a.m., G. E. Sorenson, President, presiding. PRESIDENT SORENSON: The meeting will come to order. To refresh your memory, I will read off the names of the people on the various committees. President Sorenson read off the names on the committees. Mr. Whiteside, do you wish to make an announcement? MR. WHITESIDE: Yes, I would like to 'say a word. .4s you know, this afternoon you will be on your own, and I think some would like to go to Rifle. I wonder if we could get a vote on that now as to how many would like to go to Rifle, as they at Rifle would like to know so they can provide conveyances. There seems to be about 14 or 16 that would like to go to Rifle.

CONCLUSIONS: Our experience, where we attempt to remove a continuous face with a seam more than six and one-half feet in thickness, has been rather disastrous. We have been able to open up faces and retreat for a distance of 75 to 100 feet in this particular character of coal, but after the supporting timbers have been removed for the second or third time we have found that the roof has a tendency to ride over the props and break off at the face of the coal support. However, where our coal is below six and one-half feet in thickness we have had very good success in handling the roof and breaking it off systematically with our break line of props, which are usually from 12 to 15 feet from the face of the coal. Our practice in to set props at about two-foot intervals in each direction and remove two sets of props, at the same time two additional sets are placed along the coal face. At all times we are very insistent that all props be removed from the gob and that entire coal be taken out so that it is possible for the roof to break freely and all come down, not having any supporting pillars in the gob. The conclusion of our experiments to date is that if all the supports beyond the breaking line of props are taken out as the long face retreats and the closer the breaking line of props is kept to the face the better the results will be. We have never felt it safe to have less than four rows of props to protect the machinery and men working along the coal face. We feel that the time element as to the rapidity with which these faces are advanced or retreated, is of vast importance, but to date have not had an opportunity or experience enough to reach any conclusion as to what time element is proper here with us. We feel that the crushing strength of the overlying strata will govern this to a large extent, and as ours varies considerably, it is going to he very difficult for us to reach a definite conclusion. My opinion is, that conditions may be such that rather than have a short face and retreat rapidly, it will be found that a longer facewith a slower retreat will work out better. Such a condition might give the overlying strata time to settle. The caving of roof or of control of this caving, with us, is quite closely associated with the ventilation. We find that the places where the strata overlying the coal are composed of shale, that the effect of the air on this is of very great importance. It is our endeavor, at all times, not only to remove obnoxious gases, but to keep a current of fresh air moving along the face and, of course, a portion of this travels over the gob and comes in contact with the roof and overlying strata. This, we find, helps materially in keeping the roof on the move. As it is our practice to keep water for sprinkling purposes at all places, we also use this water to keep the roof wet back in the gob. The effect of water on the shale is to cause it to disintegrate quite rapidly. MR. HOLMAN (Concluding): If there are any questions about this, I will be glad to answer them. I have some prints and also some pictures of the scraper loader and the shaking conveyors (distributes.) PRESIDENT MOSES: We wish to thank you, Mr. Holman, and also wish that you would thank Mr. Dupont for his paper. Are there any discussions? Do you wish to ask Mr. Holman any questions? (No response.) PRESIDENT MOSES: Mr. Holman, I would like to ask you how you take the photographs; were they taken by flashlight, or were globes used, or how were they taken, in a gaseous mine? MR. HOLMAN: Our mines being gaseous, we do not use the ordinary flashlight for taking underground photographs, but we have had considerable success, I think, with underground pictures by means of electric lights. We use 250 watt globes. We have six of these rigged up with tin reflectors, 18 inches in diameter, on standards, and we carry two or three hundred feet of wire connected with these six lights, and they can be turned on in the room where we take the photograph, by means of this extra wire. We set the kodak up and arrange the picture and take a long time-exposure. We usually take an

The coal stripping project of the Edna Coal Company in Routt County, Colorado, near Oak Creek, is not greatly different than many other such projects in the United States-with two rather significant exceptions. The project is at an altitude of approximately 8,000 feet, and the topography is that characteristic of mountainous terrain. The first exception-that of high altitude-makes year round operation a challenge. The second exception-that of rugged topography makes the haulage of materials a difficult task.

It is a well established fact that 60 per cent of all accidents in coal mines occur from falls of roof and coal at or in the proximity of the working face. Notwithstanding that this is well known, and has been frequently discussed by mining men, this seems to be the irreducible minimum. It is even said by those in a position to know that the percentage stated is increasing. With this, information before us it would seem that not enough attention is being given to close supervision at the working face, and until this is done we may expect to continue experiencing an increase in the accidents in this area. No workman generally feels that it is more important to finish loading a car of coal than to set a timber for protection, and many accidents happen from this source, not from a lack of knowledge of the dangerous conditions existing, but negligence in taking remedies necessary to remove the danger. It is true that nearly all state laws require the mine foreman or his assistant to visit each working face every day, but with the constantly changing conditions on account of the advance of the working faces, these daily visits may be entirely inadequate to discover possible dangers and prevent accidents. The obvious remedy then is closer and more systematic inspection and supervision of the working faces. Many accidents are caused in mines on account of not enough clearance between the rib and track or between timber and track. On all main haulage ways. there should be a space of at least 30 inches between the rib and track, or timber and track, and on all rooms not less than two feet should be left between the track and upright timbers.. A great deal has been said and written with regard to systematic timbering. We doubt very much the feasibility of adopting any standard of timbering that would be suitable for all roof conditions, and any such system in our opinion would not tend to cause a decrease in the number of accidents. The proper place to put up a prop, regardless of whether it conforms to any established system, is under a piece of loose roof. No habit is becoming more prevalent among miners and other mine workers than wearing gloves, principally flimsy canvas gloves, which afford no protection to the wearers and are the direct cause of many hand injuries. If gloves must be worn, and no doubt they will be as the habit has become well established, then they should be made from some heavy material and should fit the hands fairly snug.

(Referring to map) If there are any methods to improve on this I would like to have some suggestions on it. The maps there are on a scale of one inch to two hundred feet. At the time of each extension a letter is used and a line drawn across the entry and the room. The date of the extension is given up in the margin of the map. Here is an extension made April 6th. Extension L is shown in each one of the rooms, November 29th. N-you see the two rooms have been finished down into here. 0-the last extension, has just been stopped, and the three working rooms. Now, one of the features of this plan, when the rooms have been stopped, the line is drawn straight across. When the room or entry is still going, there is a small projection beyond the line, indicating that the next cut is changed. When the distance cannot be ascertained by the engineer, he gets the distance from the mine boss or some other source which is reliable, and that is put on in a dotted line. That gives you a complete story. Anyone looking over the map can see immediately every place that was working at the time of this extension, every place that is inaccessible, and get a complete picture. The extension of the coal is put on the extension at each extension. The survey stations are put in, showing each survey point. The pillars when they are pulled-only the pillars that are pulled are cross-hatched. The whole map is in cross-hatch without any regard as to what pillars are pulled. If a little stump is left in, that is shown on the map. The engineer only shows what pillars are pulled that he has actual knowledge of, or has been given to him in detail by the mine foreman. I believe that concludes the work on the mine map, and there is certainly room for a lot of improvement on most of the mine maps which we have been getting into the office. PRESIDENT PRYDE: Does anyone want to ask any questions? Any questions about the leasing regulations? I want to say there are several leases in the Rock Springs field, and when Mr. Smith comes on one of his visits the Rock Springs Institute have asked him to address them on the leasing proposition.

Discussion was prepared by A. L. Jones and Frank A. Rank, of the General Electric Company, read by Mr. Jones; by C. B. Officer, of the Sullivan Machinery Company, read by Mr. J. H. Emrick; by Mr. D. C. McKeehan, Chief Electrician of the Union Pacific Coal Company; and by Mr. L. C. Ilsley, of the United States Bureau of Mines, read by Mr. K. P. Marshall. Their prepared answers are inserted in the body of Mr. Harrington's paper, as answers to his questions. Introductory Remarks PRESIDENT MARKS: We have made special assignments for the discussion of this paper, and I believe these discussions are to be answered in sections, and as the different sections are read applying to this paper, we will just have a brief discussion on that particular point and proceed to the next and try and expedite this discussion as much as possible, be- cause I realize a good many of you have something to say. The first discussion is by Mr. Frank A. Rank, of the General Electric Company, Salt Lake City. MR. F. A. RANK (General Electric Company, Salt Lake City, Utah) : Mr. Chairman, while my name has been put on the program as being the one to discuss this paper, I believe Mr. Jones of our company has prepared a discussion on it, and therefore will let him talk in my place. MR. A. L. JONES: I think that it is passing the buck. However, Mr. Rank sent me a copy of the paper, and I read it over with a good deal of interest. There is one thing I want to say: Mr. Shubart, in his breezy letters, stated this paper was to be written by Mr. Harrington, assisted by a number of manufacturing and operating companies, among them the General Electric Company. We did not function. The paper was completed, and we were not consulted, and I believe that is true of the others. After reading the paper over, I dictated a few notes which I want to read, to give you the view-point that we have on the subject We do not want to minimize electrical dangers, or in any way slow down high-grade construction maintenance, but there is such a thing as overstating the case. A. L. Jones, Engineer, General Electric Co., Denver, Colo. Mr. Harrington's paper in some ways pleases me very much, but in others gives me quite a different sensation. It is so full of condemnation of most existing practices and conditions that it reminds me somewhat of the nerve-racked mother who sent an older brother to see what Willie was doing and to tell him to "stop it." His recital of electrical dangers is harrowing and if I felt it were a true picture I should feel that any of us having anything to do with the recommending or selling of electrical equipment for mines would be party to a crime. Fortunately all mines are not gaseous nor is all dust explosive or we
