Secretary's Apology: Although every effort was made to secure efficient stenographers, the railroad conditions at the time made it impossible to get stenographers from Salt Lake City. Practically all of the discussion was therefore lost, and the Secretary's apologies are offered to those whose names and remarks we are unable to record. 'We are indebted to R. Dawson Hall of Coal Age for what we have been able to print. The question was asked why belt conveyors are not more generally used. BENEDICT SHUBART: Belt conveyors lack the ruggedness of metal conveyors and require more accurate alignment. They are much used in England though comparatively scarce here. The H. C. Frick Company's belt installation at Colonial mine is an unusual installation for unusual purposes. It is hardly main haulage, but is more comparable to railroad transportation. The belts are in long sections,, nine hundred to twenty-three hundred feet, there are no particular grades, only two turns, and the immense tonnage handled justifies a quality of installation that at this day would not prove economical in most mines. EUGENE McAULIFFE, Union Pacific Coal Co., Omaha: Was much impressed on learning at the American Mining Congress that the Hudson Coal Company had mined last year 1,500.000 tons of coal from a 36-inch bed and had transported this coal to the mine cars by scrapers and conveyors. He did not believe that because one or two percent of the men around the mines were opposed to loading machines, that it should be said that the mine workers were inimical to such labor saving means. He believes that when duly explained to them they could see the advantages of the equipment offered and would be friendly to its introduction. The Sheridan-Wyoming Coal Company at Sheridan have eight Goodman Hydraulic loaders in operation in rooms .with Joy loaders driving the headings. It is not possible for the mines which had to pay high wages to compete with those whose wage scales were lower unless by the introduction of loading machines. He received a letter from Dr. L. E. Young of St. Louis, general manager of the Union Collieries Company, that his two Goodman Hydraulic machines were loading an average of three hundred tons each daily. THE SECRETARY: H. N. Taylor, president, Sheridan-Wyoming Coal Company, said Mr. Green of the American Federation of Labor told him he would have no trouble with Union Labor, and, if any local disturbances were created, they would be stopped. The Union nationally is with the introduction of labor saving equipment. J. B. FORRESTER, General Superintendent. United States Fuel Company, Hiawatha. In his opinion metal conveyors are preferred because they can be lengthened and shortened at pleasure, and so can be operated with greater flexibility than belt conveyors. W. C. HOLMAN, Chief Engineer. Phelps Dodge Corp: The Phelps Dodge Corporation have two Jeffrey belt conveyors in tandem which obviates brushing where the coal is low. MR. E. O. WIEDERANDERS, Jeffrey Mfg. Co.: Says he has seen belt conveyors in use in England and is much taken with the idea. MR. WM. MOORHEAD, Phelps Dodge Corp.: Our conveyors are in twenty-foot sections, each with a motor. Three of them tandem make a sixty-foot face. GENERAL: There was discussion regarding the size of the coal produced by conveyors. It was said that when the Gunn-Quealy Company started their operations, the coal was very large, but now there is not so much care taken to produce large coal as the market is now demanding smaller coal. The Secretary said that the use of conveyors at the Kemmerer Coal Company's mine had almost doubled the percentage of lump coal. Mr. McAuliffe questioned

The Primero mine, operated by the Colorado Fuel & Iron Company, is located 17 miles west of Trinidad, Colorado, in Las Animas County. Unusually bad roof conditions, along with heavy side pressure and other conditions causing rapid decay of timbers, all combine to create a very serious timbering problem. The height of the coal averages six feet six inches. It is a heavy coking coal and has a tendency to become easily crushed and broken down in the seam. The seam lies about 35 feet below the sandstone and the intervening formation is composed of loose shaly rock, and as the coal is extracted, the air slackens this rock to such an extent that within 24 hours, roof falls varying from five to fifteen feet in height are likely to occur. Under these conditions it is necessary to use cross bar sets in both rooms and entries, and they must be spaced no further apart than three and one-half foot centers, and be maintained within a distance of three feet of the face. Rooms are spaced on fifty footcenters, and cannot with safety be driven to exceed 14 feet in width, and 200 feet in length. The large pillar must be maintained to protect from side pressure, and the rooms must be driven up and retreated with as quickly as possible to avoid the squeeze caused by the intense side and roof pressure. Best results in extraction have been obtained by driving rooms for only a distance of 150 feet. Under these circumstances, it is readily seen that timbers of small diameters cannot be utilized in timbering any development work of a permanent nature. Entries are driven nine feet wide, and special peeled piling with an average diameter of 12 inches are most commonly used. It, is necessary to use lagging between each set of crossbars . Conditions such as these necessitated an immense expenditure for mine timber. In addition to ordinary seven and eight foot props, we used a yearly average of 65,000 feet of heavy peeled piling, averaging in diameter from 10 inches to 12 inches. Annual expenditures for timber of all classes was in excess of $60,000.00. Timber costs per ton averaged around 29 cents. In view of these exceptionally severe timber conditions at Primero, the company, in 1920, had a survey made with a view of providing some remedy to this problem. A comparison of the life of main entry timber at other bituminous mines was made, and an average life of four years was established. The actual data collected at Primero indicated an average of less than two years in the manway or "return" airways, and up to five years on the haulageways or "intake" airways. While some of this timber will stand up for a much longer period than this, a close inspection will reveal in most cases that its period of usefulness is spent. It is very essential when discussing the life of timber, especially that used on, main haulageways and aircourses, that a distinction be made between the point of service, that is, the point where it is sound, serviceable and able to carry weight, and the point of breakdown or failure, where it is no longer sound and able to carry weight. In figuring the life of timber, the point of service only should be considered as timber will frequently stand for a considerable length of time when it is entirely decayed and unserviceable. The larger part of the timber used for our permanent work was Alpine Fir, or what is locally termed Red Spruce, and the supply of this I is gradually becoming depleted and has to be obtained at a point so distant

Our next speaker this afternoon is a good friend of mine of some years. I must introduce him by way of a little story. Now Harris Sherman, many of you know because he was really in charge of everything to do with the mining industry in the State of Colorado for a good many years. Some of you may know that before he became part of Governor, Lamm's first cabinet as Director of Department of Natural Resources, he was an attorney for the Environmental Defense Fund and that caused me considerable panic as I think it might have caused some of you. I have observed Hams from the time he stepped into that office until he retired from that office to go into private practice as the senior partner of Arnold & Porter's Denver office, one of the , nation's most prestigious law firms. Hams is a Colorado native. He's lived here all of his life. He's a graduate of Columbia Law School for his law degree and a graduate of Colorado College down at the Springs for his BA. He has served in state government, but I thought it might be appropriate, since he is no longer in state government, if we used Harris, today, to tell us from a former state official's perspective what the image is of the coal industry from the seat he held in Governor Lamm's cabinet for a good many years. He has been the recipient of a number of honors that I think you should know about including Phi Beta Kappa and

The 69th Regular Meeting of the Rocky Mountain Coal Mining Institute convened in Manor Vail Lodge, Vail, Colorado, and was in session at 10:00 a.m. The meeting was called to order by Past President Joseph E. Ward, former District Manager, Denver Office, Coal Division, Joy Manufacturing Co. and now retired. Mr. Ward, after reading a brief biography of President O. F. "Os" Lewis, introduced him to the assembly. Biographical sketch read as follows: Mr. Lewis is President, General Manager, and a Director of Colowyo Coal Company. "Os" was born in Reno, Nevada. He attended the University of Utah at Salt Lake City, Utah, and later the Denver University in Denver, Colorado. His career in the Western Coal Industry started back in 1923 when he was employed by the Central Coal and Coke Company of Salt Lake City, Utah, as a clerk, then chief clerk and as a traveling sales representative for a period of 13 years. Later, in 1936, when that company was acquired by an affiliated company of Harris Coal Company, he was transferred to Denver as Assistant Sales Manager, Purchasing Agent and later as Executive Assistant to the President.

The third session of the Rocky Mountain Coal Mining Institute was called to order by Edward G. Fox, President of the Bitumious Coal Operators' Association, Washington, D. C., at 9:M A.M. He stated he had enjoyed being present at the Institute the past two years, and was honored to be asked to preside at this morning's session. Mr. Fox introduced Cloyd M. "DOC" Smith, Vice President of World Mining Consultants, Inc., Washington, D. C., whose talk, "World Trade in Coal" was illustrated with a number of graphs. (See Index.) M. E. "Shorty" Wade, Assistant Purchasing Agent, Kaiser Steel Corporation, Fontana, California, was introduced and gave a paper on "What Is Required to Realize Profits Through Purchasing." (See Index.) Mr. Fox suggested that all members take an active part in their association. He stated that much more can be done in association work than as a lone wolf. He urged all to support their organization and stay with it. It is for each member's good and not for the good of a few. Carl G. Schilbe, District Manager, Jeffrey Manufacturing Company, Columbus, Ohio, was introduced, and he presented a paper on "Results of a Study in Belt Idler Design -The Perma-Seal Idler." This paper was illustrated with a number of slides. (See Index.) "Operation of A-C Mines," was the topic covered by W. C. Painter, Service Engineer, Joy Manufacturing Company, Price, Utah. (See Index.) Each of the papers was well received, and presented a number of things valuable to all who heard them. Mr. Fox then turned the meeting back to President von Storch who read several announcements of committee meetings, and the meeting was adjourned at 11:30 A.M. for an afternoon of recreation before the banquet and dance that evening.

MR. C. M. GODDARD: Mr. Poli invented this little safety switch box. This junction box he has does improve the appearance mentioned in the underground junction boxes used in the foreign countries, where this thing is compulsory. There was some arrangement whereby the attachment could not be made with the switch in. The switch has got to be out of place before they can put the terminals into this box, which avoids all possibilities of short-circuits, except where protected on the inside of this box. In mines that are not gaseous, this is not so essential, but he has invented a very small junction box which probably. could be built for six or eight or ten dollars; if those things are necessary, for the handling of mining machines and their apparatus, takes current off the transmission line, and he has something that would meet that requirement, and I think when it is looked into it will meet the approval of the Bureau of Mines. He had this little box yesterday, and some of the members had looked it over and think, if they will look more favorably into it, they will find something to their advantage. PRESIDENT PRYDE: I think it is a good idea to bring in safety appliances and devices at this meeting. There were two more devices brought in here this morning; one a safety powder flask, and the other a carbide can. We have talked a great deal about permissible powder. It is going to take a little time to change over, and we would have to use the black powder cans. I will leave them in the window, if you care to investigate them.

Mr. Pickett's remarks were primarily concerned with the legislative aspects of the coal industry. Mr. Pickett stated that as a result of the 1952 election, only two senators and eleven representatives are now in the legislature who have ever served under a republican administration. He said there are 425 legislative issues now on the floor of Congress concerning the coal industry, but the coal industry has difficulty in legislation, because, although there are 31 coal states, only 11 states produce more than 5,000,000 tons per year, and 11 states produce between 500,000 and 5,000,000 tons of coal a year. In these states there are 44 senators and 195 representatives, less than a majority in either house, if all could be counted on to support the coal industry. An important committee to the coal industry is tile House Ways and Means Committee, composed of 25 members, 15 Republicans and 10 Democrats. Even with the support of the senators and representatives from these 22 states, legislative action is difficult.
