The Annual Business Meeting of the members of The Rocky Mountain Coal Mining Institute held during the 83rd Regular Meeting of the Institute was called to order by the president, Bernard Bernstrom at 2:50 p.m. Tuesday, June 30, 1987 in the Janss Auditorium of the Snowmass Conference Center in Snowmass Village, Colorado. Thirty-one were present and a quorum was established. The president outlined the purpose of the meeting was to inform the members of the status of the affairs and activities of the corporation during the preceding year. It was moved by Leon Jeannot, seconded and carried to approve the minutes as published in the 1986 Proceedings. The chair called for reports of the various committees and these reports will by placed on file in the RMCMI Office. Bylaws and Resolutions. Chairman Loren V. Linville reported there were no bylaws revisions. He further reported that the Board had adopted three resolutions: (1) Noting the passing of members since the last convention-Benton Boyd, E. A. Hare, E. S. Moran, Jr. and Edward Prostel. (2) Of appreciation to the Executive Secretary, officers, chairman, Diamond Jubilee chairman and committees and convention committees for an outstanding job in preparing for the 83rd Regular Meeting of the Institute. (3) To recommend to all RMCMI members that, on an individual basis, they each oppose replacing coal fired generation with natural gas generation. Membership. Chairman Leon Jeannot reported that at the beginning of the 1986 fiscal year, there were 881 active or dues-paying members. During the year, 219 members were dropped for a variety of reasons such as non-payment of dues, transfer, employed elsewhere, change of address. Ninety-six new members have been recruited for an active total of 758. In addition there are 55 Life Members, 20 senior members, six scholarship winners and seven supporters for a net total of 846. The budget of RMCMI calls for 1,000 active members and we must address and plan for those short-term prospects as they will certainly impact our membership. A full report is on file in the RMCMI office. Patrons of the Institute. Chairman Ira McKeever reported that only 59 Patrons renewed their support during 1986-87. Program. Chairman Bill Balaz announced that the convention program theme "This is OUR Life", as presented in "Past", "Present" and "Future" segments was very well received. He called for additional helpers another year and suggested that next year's program format be changed to a hard hitting one. Publicity. Chairman Tom Egan reported that of the three newsletters sent members during the year, that the most effective one was the newspaper format one and recommended its use next year. RMCMI hired Bob Jacob who heads his own public relations firm to solicit advertising for the Proceedings on a contract/ commission basis. He attended the convention for this purpose and to solicit business card ads. A full report is on file in the RMCMI office. Scholarship. Chairman Keith McGinnis reported that five of the six scholarship recipients were present at the convention. Each was introduced to the membership at the Tuesday morning Scholarship Breakfast, presented a plaque and responded. The input from each winner was most favorable to the program. Each was appreciative of the many contacts made and the educational seminars and programs. The selection process started in March and was completed in May, except for one university which had difficulty in providing a candidate. It is suggested that the initial contact with the institutions be made in December and completed by April 1. This year, for the first time, three of the six universities were visited for the purpose of interviewing the candidates. They were Colorado, Utah and Wyoming. A very positive feedback was received from these schools and it is recommended that the practice continue. CONVENTION COMMITTEES Convention Arrangements. Doris Finnie presented the following report: As a professional meeting planner, this Diamond Jubilee convention was indeed a great challenge. One meal was added to the package and thus increased the individual cost. Snowmass Resort Association is unique in that they utilize a conference coordinator who acts as the middle man between myself and the usual persons we deal with, like AV personnel, the chef, the banquet director, the steak fry personnel, the Sunday tour etc. so the office had to become creative. For instance, we learned early on we could not deal with the local florists. It cost us lots less to buy our flowers wholesale in Denver, have my husband drive them up and our West Virginia daughter to arrange them! But, finally her floral arrangement class at CSU paid off! This was truly a Finnie family orchestrated convention. Our Lakewood daughter acted as Scholar-

Some time after my arrival in Rock Springs to fill a short engagement with The Union Pacific Coal Company, Mr. Dickinson informed me that he had placed me on the program for a paper entitled "Mechanical Loading in Indiana." Since development of mechanical loading operations on a genuine coal producing basis for that section began near Oakland City, Indiana, and rapidly spread over Southern Indiana, Western Kentucky and Southern Illinois simultaneously, the results referred to are in many ways common to all three states. Prior to December, 1922, several attempts at mechanical loading had been registered, notably among which were installations of the Jeffry Entry Driver, and the Meyers-Whaley loader. The object of most of these earlier installations was quick development rather than lower production costs in face loading. In this measure it is claimed the machines were at least partially satisfactory. Three items which seemed to delay rapid progress in the adoption of either machine were, excessive first cost, height of coal seam necessary, and timidity of the operator relative to the labor situation which might develop. When the Joy machine was put on the market in the form of the 4-B.U., with a clearance overall which would perform in coal slightly under five feet in height, and at a cost price of less than one-half that of other machines being sold, many operators were at once ready to take a chance along with the manufacturer. This desire was accentuated by the difficulty to operate coal mines at all at prevailing production costs. This condition also made the coal miner more receptive to machinery which would give added employment to the field. At the convention held in Cincinnati during May, Mr. .Joy stated that about 200 of his machines were in operation at that time. Mr. Whaley said that about 40 of his were in use in coal mines. It is probable that of the above sum 75 machines were installed in Indiana, Illinois and Kentucky. Since that time, possibly 50 more machines of later design have been added. Like many of our troubles, those which seemed most difficult to overcome, proved in the end to have been least of all, and in this case the sup¬posed resistance which labor would advance has been more or less imaginary. In Illinois and Indiana a scale of wages is being accepted which is consistent with average earnings of machine men. The fact that a large number of coal operators want and are buying more loading machines has encouraged mining machinery manufcturers on every hand to devote renewed vigor to the cause and it is generally understood that new types and models are being developed both in factories and mines with the coal industry eager always to see the latest development. I understand that at present the Goodman, the Jeffry, and the Sullivan machinery companies are each offering new designs to meet Indiana and Illinois requirements. It is not strange that with so many installations many were made as a result of an impulse to ride the band wagon without any serious attempt to study the results or draw any conclusions from the experiences of others with loading machinery.

President Robert Wilson opened the meeting at 9:00 a.m. He introduced William A. Bear, General Manager Bear Coal Company, Inc., Somerset, Colorado, who presided over the session. George Nugent, Peter Kiewit Sons' Company, Sheridan, Wyoming, presented a most interesting film "Montana Mine Reclamation." His biography follows: George Nugent first entered the coal business in 1943 when he developed Peter Kiewit Sons' Co.'s first coal mine-Big Horn Coal Company at Sheridan, Wyoming. Since that time he managed an expansion program for P.K.S. in mining that resulted in the development of two other producing mines - Rosebud Coal Sales Company at Hanna, Wyoming and Decker Coal Company at Decker, Montana, in which Pacific Power and Light is a partner. Applications are now pending for a third mine. Black Butte, a joint venture of P.K.S. and Rocky Mountain Energy Company, near Point of Rocks, Wyoming. Nugent is a Past President of the Wyoming Chapter, Association of General Con- tractors, Wyoming Mining Association and Rocky Mountain Coal Mining Institute. He was President of Big Horn Coal Company and Rosebud Coal Sales Company as well as Manager of the Mining Division of Peter Kiewit Sons' Co. and Decker Coal Company when he retired Jan. 1, 1975.

On Monday, June 27, 1921, at 6 p. m., twenty-four members of the Institute from. Colorado and New Mexico, left Denver on the Union Pacific for Rock Springs, Wyoming, arriving there at 9:42 a. m., June 28th. The party was met at the depot by the Rock Springs committee and a large number of the local Institute members. The day was spent in visiting the Central Power Plant of, the Union Pacific Coal Company and adjacent mine, the new 'E Plane, the Reliance, Dines, Winton and Sweetwater coal properties in the district. At noon a very elaborate lunch was served in the First Aid Building at the Reliance mine, which was most heartily enjoyed by all. In the evening the members and friends visited the new Rialto theater and saw the pictorial exposition of the' "Sky Pilot". The evening terminated with a dance in the ballroom of the Masonic Temple from 9:30 until midnight, concluding one of the most enjoyable days which the Institute has ever spent in Rock Springs. At 12:3o a. m. the original party, augmented by six members from Rock Springs, were again enroute to Salt Lake City, arriving there at 8:30 in the morning of Wednesday, June 29th. The Hotel Utah had been selected by the local, committee as the headquarters for the convention, and the majority of the -members at once proceeded to that place where the books were opened and the paying of dues and registration of the members were carried on until 11:45 a.m. At noon a majority of the members were entertained at the L.

PRESIDENT LITTLEJOHN: The paper of Mr. Emrick will now be open for discussion for about twenty minutes. The meeting is now open for discussion. MR. EMRICK: There is some question that may have occurred to you at different times, that is how are you going to tell when the bits are properly made? A fairly good rule to go by is when the used bits come out of the mine, if half of them are bent and half of them are broken, the average is pretty good MR. GEO. B. PRYDE (Union Pacific Coal Company): I would like to ask Mr. Emrick if he has any figures as to the saving of Dower with the different styles of its. MR. EMRICK: I suppose you mean chisel point bits and pick point bits? MR. PRYDE: Yes. MR. EMRICK: So far as I have been able to learn, the only reason why chisel point bits are used is to prevent coring that might be done by the cutter chain. The pick point bit, of course, is the proper thing to use. It can be used when the position of the cutter links in the cutter chain is right. I do not know of any figures which give power consumption ratings on the use of pick point and chisel point bits, but there are tests and ratings, etc., which have been taken- which have been tested as against different bits, which have been given proper clearances against bits not having been given proper clearances, and they will run,-in their saving in power, they will run 20 to 25 per cent. MR. A. C. WATTS (Chief Engineer, Utah Fuel Company) : I would like to ask Mr. Emrick if he has any record showing the saving in power on using the alloy steel chisel bits. I know that several experiments have been made; I do not recall the figures now, but we had a very decided saving in power. MR. EMRICK: I haven't any of the records. Do you think that is because of the steel that has been used? MR. WATTS: Well, they were all sharpened by the same man and used in the same machine, and at the same shop. I do not know the composition. It is "Red Star" Vanadium that I had in mind. MR. EMRICK: I have not seen any records. Some companies are using the tool steel bits because they stand up a little bit better. MR. BENEDICT SHUBART (Secretary) : I was going to ask Mr. Emrick about that question. There is one company that does not recommend tempering the bits. They recommend using not exactly self-hardening steel, but one that is bard enough without quenching-they use 80-90-point car- bon but about a 70-point manganese, not exactly self-hardening steel, but they do not temper this at all. Will Mr. Emrick state if a steel of that kind could be worked in the bit sharpening machine that his company makes, as it

GREETING Hail! Hail! the Coal Miner, Damn the operator, damn the operator, Hail! Hail to mining coal We'll tell 'em how to run the mines. Oh, we'll send out a questionnaire And we'll quiz 'em, we will razz 'em for fair, We'll ask about the profits and order them to stop it Tell the world we're going to stop right there. Hail! Hail! etc. NASH AND PRYDE Tune, "Gallagher and Shean" There are two mining men, the best I've ever spied, One is Mister Harry Nash, the other Mister Pryde. When these two fellows meet it surely is a treat, The things they do, and the things they say, And the funny way they greet. Say, Mister Harry Nash, Oh, Mister Harry Nash, Tell me what's on your mind this evening, Mr. Pryde; I have heard an awful lot of that steep coal mine you got, And I wondered if some one had up and lied. Oh, Mr. Pryde, Oh, Mister Pryde, It's so steep it seems to lie upon its side. If it were steeper than it is, it would put us out of biz, Absolutely, Mister Harry Nash, positively, Mr. Pryde. Oh, Mister Harry Nash, Oh, Mister Harry Nash, Somebody said that at this new mine you've begun 'Fore you mined a lump of coal, had to burrow like a mole, And of rock you dug out many a million ton. Oh, Mister Pryde, Oh, Mister Pryde, I hate to think of all the dough I supplied. I believe the Moffat Tunnel bore won't cost a single dollar more I don't think so Mister Harry Nash, I agree with Mister Pryde. PARTING Tune, "Leave Me With a Smile" Though a sea of strikes and low price squabbles, Follow us the while; Once a year we gather just to show them whether We still wear-a smile; Rocky music coal still packs a barrel full Of timely fun sans guile, Rocky Mountain Institute can follow such And smile its yearly smile.
