One of the most dreaded things which mining men sometimes have to contend with is underground mine fires, which are both dangerous and expensive. In the Reliance mines we have had considerable trouble with mine fires. We have at the present time five different fire zones, three of these zones give us considerable trouble and the other two have not given any trouble since they have been walled off. Fire Zone No. 1 comprises No. 2, 3 and 4 South Entries, about 50 acres are enclosed in this zone. Fire Zone No. 2 comprises the main drift entry from the mouth to the Old Boundary Plane and extends to the crop line, about 10 acres are enclosed in this zone. Fire Zone No. 3 comprises 1 and 2 North Entries from the main slope to the Old Boundary Plane, a distance of about 1,200 feet, about 15 acres are enclosed in this zone. Fire Zone No. 4 comprises 11/2 and 2 North Entries, a distance of 1,100 feet between New Slope and Old Boundary Plane, about 15 acres are enclosed in this zone. Fire Zone No. 5 comprises the inside end of No. 11/2 and 2 North Entries and 3 North Entry from the New Slope to 30 room, a distance of about 2,600 feet along No. 3 North Entry, about 20 acres are enclosed in this zone. The first mine fire started in No. 2 South Entry in No. 1 zone in 1914. Inside of No. 7 room on the high side of the entry, there was a soft piece of coal. There were no rooms driven in this coal and one day a fire was discovered in the solid pillar on the high side of the entry, work was started at once to load out this fire. and several places was driven into the pillar and cribs built where the coal was taken out, but this method proved a failure and a sand pack was put up along the entry between the track and the high rib. This consisted of timber set about 3 feet from the rib and 2-inch boards put behind the timber and sand or adobe put in between the boards and the ribs, and this method gave very good results except that it required close watching as the sand would settle and let the smoke out between the roof and the sand. Fire broke out in No. 3 South Entry in No. 1 zone in the summer of 1919. We sealed this fire off by building 36 fire stoppings, which also enclosed the fire in No. 2 South Entry and we have never had any trouble with fires in this zone since it was walled off. The fire started in No. 2 -zone in 1919 and has been very active ever since. When this fire was first discovered we built new stoppings in front of the old one in the room necks; we also opened up some of the room necks and loaded out part of the burning coal and rock but this did not help any, the fire, would burn out around the stoppings also burn along the roof between the top coal and the roof sometimes nearly across the entry. Several holes were drilled from the surface to the fire area and flushing the fire was tried but this was also a:\, failure, the rock above the coal was so hot that the mud would dry in the hole and fill it. In 1921 we started to take down the top coal along this entry, timber the entry and put 2-inch boards behind the timber and fill in between the coal and the boards with sand or adobe. We have at present over 1,000 feet of this work done and it has given us better results than any other method that we have tried. As the coal burns out behind the timber the weight breaks the timber and it is necessary to renew some of it. Fire broke out in No. 1 North Entry in No. 3 zone in 1922. There was a stopping in this entry that had been put in when the entry was finished some few years before. The fire burned around the stopping on the low rib of the entry, we built another stopping in front of the old one taking down the top coal and extending it up to the roof also digging in both ribs and setting the stoppings into the coal about 18 inches. This fire did not cause any trouble until June, 1924, when we discovered this fire was very active on the inside

The Forty-Sixth Meeting of the Rocky Mountain Coal Mining institute convened at the Hotel Colorado, Glenwood Springs, Colorado, June 19, 1950, at 10:00 a. m., G. E. Sorenson, President, presiding. PRESIDENT SORENSON: The meeting will come to order, gentlemen. I note from the program here this morning that you were supposed to have an address by the president. I can assure you, gentlemen, that the president is not going to make an address, so you don't need to squirm in your chairs. I do want to say it's certainly a pleasure to be here. I am sorry that I wasn't here last year. Apparently my absence lent consent, and I think it would be a good warning to every member of the organization to be here for all the meetings for your own protection! It's always a pleasure to be here and meet again with some of our old friends and meet a lot of new ones. It always interests me at these meetings to meet with the rugged individuals that operate the coal industry. They have to be rugged; they couldn't be any other type of men and live in it. I also know that it takes a good rugged man to fight this game nowadays. I feel that the men who operate the coal industry are fighting a battle against socialism. You all know we are the first industry they have their eyes on. If they take over our industry, they will take over everything else.

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.

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.

Those who remember the years of patient effort and the slow results obtained in the first introduction of electrical coal cutters and locomotives will, I think, admit that mechanical loading of coal is unquestionably being established at a much more rapid rate than any previous application of machinery to reduce manual labor in mines. There are many operators who consider the progress of the loaders today as slow, but considering the number of years it took to thoroughly establish electrical coal cutters and locomotives, and comparing it with the short time that the mechanical loader has been on the market, and the results that have been obtained today, they will admit, I think, that the progress of the latter is much more rapid. It is about 35 years since the advent of the electrical coal cutter and electric locomotive. Their use has brought about these improved conditions, increased tonnage per mine and other features, which are of assistance to the installation of mechanical loaders. The management and the technical staff in practically all of the American mines are trained in the use of electrical machinery and understand its operation, care and maintenance. . There is frequently, a surplus of electrical power and wiring available to take care of the small requirements of the electrical loader. The mechanical loader, therefore, starts today with the ground prepared for it. Those manufacturing companies who have had years of experience in the design and construction of mining machinery, know in a large measure what to incorporate in their designs to make the parts of the new type of machine effectively strong and to operate with efficiency under the severe conditions encountered in mining service. All these advantages greatly assist the success of a new type of machine such as the mechanical loader. In spite of these advantages, however, there are bound to be some failures. All new types of loaders have to be developed. We hear of some that are a success and some that are set aside. The field of application of each type and its limitations first must be determined by actual operation. The earlier loaders had to be changed and improved in design as weaknesses developed. Not all of the new types of coal loaders have been built by mining machinery manufacturers of long experience, and the lack of experience in this line is responsible for some of the early failures. The coal mining company staffs and also those of the loader companies had to learn what the operating factors were that made mechanical loading a success. The difference in results obtained by loaders in different properties under similar physical conditions indicates that the mine management is a very large, if not the major factor, affecting the efficiency of mechanical loading. Many articles have been written on the question of loading. The subject has been quite fully discussed at recent coal meetings and in the technical press. It is not always as easy or simple a matter to form conclusions as may first appear as to one's own particular loading problem. Mechanical loading is a comparatively new art, and many companies while claiming that loaders are quite successful, do not have an accurate line on the actual saving they are affecting. Many of them have only a few of the factors taken into account in their costs. Many loaders have been generally bought without very careful consideration given to all details and except where extremely favorable conditions prevail, failure resulted. When contemplating the installation of mechanical loading, one naturally desires to select the type of loader that will, fit his mining conditions. The things
