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

Men and institutions are what they are largely because of inheritance. Out of the past comes experience that enables men to build more wisely than did preceding generations. The field of possibilities has widened as the horizon of men's vision has been extended. The realization of these possibilities has depended largely on the application of men's natural endowments, brain and brawn, to the problems at hand. In the field of mechanized mining, Wyoming has a greater percentage of men with vision, who have a realization of the possibilities of mechanized mining, than any other state in proportion to tonnage production. With the introduction of mechanized mining systems have come problems that have caused the men who are connected with the safety work much thought. Discussions on mechanical drilling, cutting, loading, conveying, haulage, etc., have come in for their share of the debate. There have been a few attempts made to show that mechanical mining is safer than are the more primitive ways of doing underground work by man power. We also have a number of places in the coal producing States of the United States, where the mechanized systems have been abandoned chiefly on account of the safety element involved bringing about condemnation of the system by State inspection forces. Certain types of scraper systems have been condemned, and some have voiced opposition to long faces. This would lead us to believe that the question is still a debatable one as far as the safety element is concerned. It is only fair that we discuss the operations of mechanical systems and from the results obtained take analysis of conditions as they exist, basing our conclusions from the results obtained.

Profiled below are the eight RMCMI 1999 Scholarship Award winners. Seven of the eight attended the 95th Regular Meeting and convention at Crested Butte, Colorado in late June. Each spoke during the Scholarship Awards Monday luncheon and shared their goals with attendees. In addition to receiving a $1,500 tuition credit, thanks to the Patrons of the Institute annual funding of scholarships, each received recognition at the luncheon with a brass plaque signifying this honor. The winners are guests of the Institute Sunday through Tuesday and have an incredible opportunity to meet many in the coal industry who could be potential employers. The state vice presidents host the winners and pay for their travel and hotel expenses. This is a continuing scholarship and may be renewed for tuition credit again in the senior year if they remain a full time student and if recommended by the dean of their college or university. A resident from each of the eight member RMCMI states is selected by the Scholarship committee from Board approved institutions. Criteria for these annual awards is that the recipient (1) is a full time sophomore student who will use the tuition credit the junior year. (2) Be both a U. S. citizen and a legal resident of the member stare.

CHAIRMAN I. N. BAYLESS: Will you come to order, gentlemen? They told me that you had a very interesting meeting yesterday and a good time last night. Our program is rather long this morning, and I am not going to take up any of your time, as we got started a little late. I will ask Mr. Marchant to make a few announcements. (Announcements.) SECRETARY MARCHANT: I just noticed in this morning's paper a rather serious accident at Hobbs, New Mexico, in which George Kaseman, a former President of the Institute, and a loyal member ever since its organization, was killed. I think that this meeting should go on record and prepare a resolution of condolence, etc., and with your per- mission we will have the Committee on Resolutions do that. I assume that will be all right. CHAIRMAN BAYLESS: Our first paper and discussion this morning will be Education of the Miner, by Thomas Allen, Chief Coal Mine Inspector of Colorado. Mr. Allen.

MR. STOUT: The picture shows the plan of the "V"-system as worked at Berwind mine, in a small strip of coal adjacent to the 4th right entry. The dotted line (indicating) show the position of the break rows as set for each of the three consecutive breaks. In two cases the break rows failed to function properly and as a result, the roof caved along the points of the "V's" as well as back along the faces a short distance. This affected the ventilation to a certain extent, but was remedied immediately by cutting through the points near the cave and setting additional timbers. At the present time we are putting in the break row of heavy red spruce props, making the row straight instead of curved as is shown in the picture; in this way we believe we can better control the breaks. The three "V" entries were driven up 14 feet wide, for a distance of 260 feet without cross-cuts. A very neat and substantial line brattice was carried up each entry as the places advanced. The principal factors in determining the success of this system are ventilation, roof control, and transportation. We are well pleased with the results from these three "V" places and now have four other places, about 500 feet to the west of these, driving at the present time in which we hope to get still better results. A MEMBER: What centers did you use there? MR. STOUT: We used 70 feet. This may be increased or decreased according to local conditions. MR. F. W. WHITESIDE (Chief Engineer, Victor-American Fuel Co.) Will you please describe roughly how your cars are handled? MR. STOUT: Cars are brought from the parting and pushed up along the faces by a storage battery locomotive. The faces are about 70 feet long and we found that five or six cars can be loaded and transported very conveniently. It is important to get a quick exchange of cars, and in this way we were able to keep the shovelers busy at all times. A MEMBER: What is the grade in your "V" entries? MR. STOUT: Five per cent in favor of the loaded trip. A MEMBER: What is the angle of your "V" faces? MR. STOUT: The angle at the throat is 45 degrees. MR. SAMUEL ANDREWS: In what direction does the air travel? MR. STOUT: The air travels down the dip entries and is deflected up the first "V" entry, and travels along the points, and returns down the last entry. There is no more difficulty in ventilating "V" faces than in ventilating rooms, providing the points are kept open. A MEMBER: What amount of air do you have in that section? MR. KAISER (Superintendent, Berwind Mine): Eighteen thousand cubic feet per minute. MR. ANDREWS: It is necessary, Mr. Stout, to brattice these places?

Loading mechanically has of late become the most widely discussed subject in connection with coal mining and has even equalled. the discussion of safety measures as a topic of interest. The subject has been discussed in the various mining journals and by well. informed persons at the Mining Institutes, so it would appear; that all has been said that can be said until further experiments bring out new lines of discussion. It is, therefore, not the intention to present this article as a technical discussion of the subject of mechanical loading as a whole, but rather as a plain talk on machines with which the writer has had personal contact. In 1919, during the first period of post-war depression, a Pennsylvania coal company employing union labor became interested in the possibilities of mechanical loading with the hope of reducing their mining costs, which were and are yet too high to meet competition from the non-union fields of Somerset and Westmoreland counties. Of several loaders presented for their consideration the model of the Joy loader shown by Mr. Joseph F. Joy, seemed to hold the greatest possibilities, and after extended study, the management decided to invest in a machine of this type. A machine was built, which as far as the writer knows was the only one of its type ever put on the market. This machine arrived at one of the mines early in 1920 and was put to work immediately. It was a forerunner of the present 4-BU and 5-BU types, but differed from them very radically as to design. In general the machine consisted of the familiar Joy gathering arms and a short conveyor which discharged into a steel tank which held about four and one-half tons of coal. This tank was emptied by a second conveyor which placed the coal in the mine car. The object of this conveyor tank was to provide storage room while changing cars and to allow the machine to load on the entry while the room was short. This plan was very efficient and from our experience was worth retaining, but has been abandoned by the Joy Company on account of its making the machine unwieldy. The whole machine was mounted on caterpillar tractors which were driven by two 10-H.P. Westinghouse series wound motors, each having its own controller, the controllers being arranged in tandem so as to be operated by the same handle. This very ingenious scheme which is shown in Figure 4, was supposed to make it possible to steer the loader by the controllers. By swinging the handle one way both motors moved forward, by swinging the handle the other way both motors moved backwards and by twisting the handle as shown by arrows, one motor moved ahead and the other back, thus causing the machine to turn. This scheme proved a failure as the loader was too temperamental and erratic in its operation. After Mr. Joy, himself, narrowly escaped serious injury, this device was taken off and the controllers manipulated separately. This system never proved satisfactory and was abandoned' for
