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.

In presenting a summary of the uses of fine and pulverized coal the writer has borne in mind that we are not trying to determine what a combustion engineer should know but we are only trying to find out in what ways the consumption of slack can be stimulated. First discussing the use of powdered coal it can be stated that it has passed the first experimental stage but is still capable of much development and improvement. It has already found successful application in stationary and locomotive boilers, cement kilns, calcining furnaces, reverberatory smelting furnaces and many other types of furnaces, such as open hearth furnaces and annealing furnaces. For stationary boilers it seems to have been thoroughly demonstrated that powdered coal is more efficient than stoker installations. Over-all efficiences of boiler and furnace in stoker installations of the best type run from 70 to 76 per cent; whereas the efficiency of powdered coal installations averages slightly over 80 per cent. However, due to the increased cost of pulverized coal, the increased efficiency of these installations over stokers, from a money stand-point, will not be more than 1 or 2 per cent. The fusing of the ash in pulverized coal installations has given some trouble but apparently is easily overcome, on the other hand the fine ash, which is carried along with the draft, causes trouble both in the boiler and by settling on surrounding buildings or ground. Offsetting the disadvantages the great advantages of pulverized coal for stationary boilers seem to be: First-the ease with which a change in the load on the boiler can be taken care of. Second-when a boiler is cut out for a short period the "stand-by" losses are much less and, Third-a much poorer grade of fuel can be used. In many cases where pulverized coal has been used it has replaced slack coal which is of little advantage to the coal operator. However,, in other places it has replaced gas or oil and this is where the coal man is interested. Pulverized coal has the same advantages as the liquid or gas fuel but the question as to which is preferable depends on their relative cost at the point of use. In small stationary boilers where stokers are not used, very frequently the larger sizes of coal are, and it would be an advantage to the coal industry for them to be converted so as to burn pulverized coal, but so far there are only records of a few of such small installations having been a success and there is apparently room for a large amount of experimentation. In furnaces, such as smelting and assaying furnaces, annealing furnaces, etc., slack coal is not used and where pulverized coal has been installed it nearly always replaces fuel oil or gas. Just how much increased consumtion of coal can be made by pulverizing it for use in furnaces of this type can not be determined but it seems worthy of investigation. For locomotive boilers pulverized coal has found some application up to date but where it was being used in the United States it was stopped when we entered the war. In Brazil, however, the Central Railway has been using pulverized coal for locomotives with excellent results. If it could be possible to apply it to locomotive use where fuel oil is now used, or the larger sizes of coal, it would certainly make a big difference in the slack situation. Now as to the uses of slack coal without pulverizing. The writer's investigations lead him to believe that the greatest opportunities in this direction are in the line of increasing its use by apartment houses and small home owners. In fact in looking into the subject I found that a number of men in Salt Lake City are using run of mine coal in the usual type of house furnaces, some of them by separating the fines and wetting them down before feeding to the furnace claim they get no loss whatever through the grate. However, for best results with fine coal different types of furnaces must be installed and for apartment houses it would seem necessary to have either a small automatic stoker or else spray the fine coal in with an air blast from

Mr. Griles did not make his speech available for reprint. Looking Down the Road: The Environmental Side of the 1990s and Beyond Environmental Social Responsibility Love Canal, Buffalo Creek, Widow Combs, Bohpal and Three Mile Island are familiar names to all of us-names which evoke memories of environmental tragedies. These memories, as well as memories of other environmental disasters, lead us to pose this question: What is the nature of the environmental social contact between industry and society? The manner in which one answers this question will. in large measure, answer the question of where one thinks environmental issues will go, or should go, in the 1990s and beyond. The history of the evolution of the environmental movement will be helpful in defining and under- standing just what society's environmental responsibility is and, perhaps, what it will be. To Define the Future Start With the Past The common law, which most of the United States adopted from the English system of jurisprudence, traditionally considered pollution control and other environmental issues to be a matter of determining the relative rights of private property owners and of individuals. Legal and equitable theories, such as nuisance, negligence, trespass and the law of riparian rights, were utilized to allocate responsibilities between parties under the common law. The discharge of pollutants into streams and into the air was by and large considered acceptable, at least up to the point that another's "reasonable" use of the same air or waterway was significantly impeded. Further, the judicial decisions interpreting the applicability of the common law to the protection of the environment generally reflected the social and economic pressures of the age. During the Industrial Revolution, the decisions and policies had a marked tendency to favor industrial development. Jobs and industrial growth are deemed as important, and in some cases more important, than the protection of people and property. Additionally, the idea of a social responsibility, beyond that owed to a competing land or water user, was nearly alien to the early common law.' One could even go so far as to say that, had there been a social environmental contract under early common law (which, of course, there was not); but if there were, it would have been to promote actions which facilitated industrial development, even at the expense of the environment. Post-World War LI industrial expansion brought with it a growing awareness of limits on the environment's ability to absorb increasing levels of pollution. Thus evolved an era of social and political adjustment, as society began to shift away from supporting big business and industrial development and toward supporting domestic government programs and limits on industry. States gradually stepped in with efforts to address environmental issues. The Pennsylvania Clean Streams Law and the West Virginia Surface Mining Act of 1939, while lax in comparison to today's standards, nevertheless marked definitive efforts toward altering the balance between industrial development and environmental protection Pollution control continued to be viewed as a state responsibility through the 1950s, until Congress began, for the first time, to allocate funds for federal research on air and water pollution and to implement

Chairman Doc, distinguished guests, and fellow members of the Rocky Mountain Coal Mining Institute: It's a genuine pleasure to meet with you again at the 54th regular meeting. I might add that it is always pleasant to be at the top of the batting order. The field is wide open since there is no danger of repeating something already said. At the same time, I am aware that the lead-off speaker has a responsibility to avoid stepping on the toes of subsequent speakers. I promise to confine my remarks to areas other than those to be covered by the well qualified speakers that follow. During our meetings at this convention, many fine papers will be presented. Our thanks are due Bob Williams and his hard working program committee for the superior selling that brought so many eminent speakers to our meeting. And, of course, our special thanks go to Doc Schloss, general chairman of this meeting. Doc and his able colleague, Stan Shubart, have been the spark plugs that fired up all of the arrangements we are enjoying here in Glenwood Springs. I'm sure all of us are appreciative of the many hours Doc has devoted to seeing that our meetings will be pleasant and profitable. When we mention arrangements, we always think of that master arranger, Fred Whiteside, who, as a charter member and secretary-treasurer of the Rocky Mountain Coal Mining Institute, has had more to do with more matters around these parts than just about anyone I can think of.

MR. FOOTE: This paper deals with blasting and mechanical loading. The Union Pacific Coal Company does all of its blasting with permissible powder and electric shooting, but this paper deals principally with blasting in connection with mechanical loading. With the introduction of mechanical loading into the coal fields of southern Wyoming one of the main problems to be taken into consideration was the drilling and blasting of the coal. The methods used in blasting coal for hand loading were found to be ill adapted to the mechanical practice, so numerous tests were conducted from time to time to determine a system or systems whereby the coal might be blasted in a form to be easily handled by the loading units. The general practice in blasting coal for hand loading, for example in a room 24 feet wide and seven feet high with an undercut of seven feet, would be to shoot one or two strong breaking shots in the center and one on each rib. While much of the cut would be blasted down in good lump, some coal would be left hanging at the back and ribs. With hand loading, the miners would have time to pull this coal down with a pick between cars and eventually would clean up the place ready for the cutting machine. The loading machine, however, cannot get this coal down and its operation would be delayed while the men were doing the necessary pick work.

PRESIDENT LITTLEJOHN: I have every reason to know Mr. Pryde was carrying out some experiment a while ago in some of his mines. He and I had a little correspondence on the question, and I think he may have a word or two to say about it. He has not been on his feet today at all. I will ask Mr. Pryde to tell us what he has to say. MR. PRYDE: I have not very much to say about shooting coal with permissible powder as far as slack is concerned because we are not in the commercial business. All of our coal goes to the railroad and a very large part of it is crushed for use in the stokers of the locomotives. We are on a 100 per cent permissible powder basis and as far as I am able to see, I do not believe that the percentage of slack is increasing with its use. We find it hard to convince our commercial neighbors of this fact because they are naturally very much against increasing their percentage of slack on ac- count of the low price received for this grade of coal. I, personally, believe that where a change is made from black powder to permissible powder the percentage of slack will be increased for a time because the miners have been accustomed to using black powder and they are rather suspicious about going to the permissible powder and I do not believe that we can blame them very much. So the tendency with them is to use too much powder. We have gradually overcome this, although, as I said before, we have not kept close track of the production of slack. However, we try to get as large an amount of lump coal as possible. Broadly speaking, I can say from observation that in my opinion there is very little difference in the percentage of slack with the use of the permissible powder that we have today than there was with the use of black powder. I also get this information from our mine superintendents. Mr. Peterson and the other explosive men have been very helpful to us in the use of permissible powder and I confess I have to take everything back that I said several years ago. At that time I was against permissible powder, particularly on account of the cost, but, with the newer permissible powder, we have gotten the cost down very well. I know today that the cost of permissible powder in the coal mines of the Union Pacific Coal Company is less than when we were using black powder. I know this because of the fact that we kept a record of the number of tons we got with black powder, and the number of tons we get with permissible powder compares very favorably in cost. I know this, too, because of the fact that our employes, except in the first few weeks of using permissible powder, have made no demand upon us for any in- crease ill pay to offset any added cost that might accrue in the use of permissible powder and the fact that they have asked for no increase is very conclusive proof to me that it is not

The subject of Premium Payments for Mechanical Loading was given consideration by the management, having in mind they would prove an incentive for increasing the tons per man shift, make for a lower production cost and allow the ambitious workman an opportunity to augment his earnings over the regular day wage rate, a standard of performance having been established by the operator which would be expected from the employee. Any performance above the standard is looked upon as a saving to the operator of which the employe benefited to the extent of receiving a certain percentage of the saving effected. The premium must be high enough to be worth while to the employee and low enough to in¬sure a saving to the employer. This method of sharing tends to pay men in accordance with their ability and effort. One of the principal advantages of this method of sharing is that a better class of labor may be attracted. Greater earnings furnish an incentive to increased tonnage. Workmen who prove themselves aggressive are readily noticed by supervisors, and, by shifting men to different places and to different working conditions, the crews are made more efficient and the inefficient workmen may be singled out and eliminated, thus permitting better results and better operation of the mechanical loading equipment. This is also evidenced by the fact that men become their own competitors, also working in competition with other crews. In order to do this, without neglect to the care and protection of the loading machines, men are educated to the proper handling and care of the machinery, keeping it in shape and everything clean in general, which has shown good results.

Bureau of Mines Technical Paper 172, by S. H. Katz and H. C. Porter, entitled "Effects of Moisture on the Spontaneous Heating of Stored Coal", says at the outset, "Spontaneous fires in storage piles of bituminous coal' have been the source of trouble and loss since the industrial utilization of coal began. In Europe the idea arose that spontaneous combustion is more liable to happen during wet weather than during dry. Statements favoring or opposing this idea have crept into the literature. Conflicting conclusions, based on experiment as well as opinions based on observations of various degrees of reliability, are given in most of the recorded discussions of the subject. "Because of the uncertainty of the effect of moisture and its seeming importance among the conditions that affect spontaneous combustion in stored coal, the work described in this paper was undertaken by the Bureau of Mines. The experiments showed that a coal from Illinois oxidized faster when dry, whereas a sample of Pittsburgh coal oxidized faster when moist. These discordant results and similarly inconsistent results from the observations of different investigators may be coupled with the fact that under actual conditions of, storing, both coal and air always contain a considerable amount of moisture." The foregoing report of the investigations of the Bureau demonstrates that the mystery of spontaneous combustion has not yet been solved. This fact adds to the fascination of the subject. I became interested in the matter about ten years ago in observing what was probably one of the best exhibitions of this phenomenon. The old dump at Castle Gate No. 1 Mine contained boney coal and track cleanings generally. In winter when snow fell upon this old dump, the snow was soon melted by the heat of the dump which was comparatively warm at all times. Within 48 hours afterward little blue flames were in evidence on the surface of the pile. Few of the gas feeders were sufficiently constant to maintain a steady flame at any given point, but shifting emissions of gas were ignited one by another, resulting in a continuous popping and apparent running about of the flames. Another interesting exhibition of spontaneous heating was to be seen a few years ago in the storage coal piles of the local sugar factories. This coal was piled in concrete lined pits and the latter were filled with water. However, or this occasion the coal extended above the surface of the water. At every plant where this condition existed the coal was affected heating, and in each case the affected area was in a plane horizontal to and from 8 to 1.4 inches above the water level. The height of the hot area above the surface of the water appeared to be affected by the fineness of the coal. It is well known that oily rags have a tendency to heat when allowed to accumulate in some location protected from free air circulation. For some reason, as yet unknown, this does not apply to petroleum or its derivatives. Now, the most common explanation of spontaneous combustion is that the combustible material oxidizes by being brought into contact with air in the presence of moisture, the theory being that the moisture acts as a catalytic agent. My theory is that spontaneous combustion is due to oxidation of combustible matter by free oxygen carried in solution by a liquid, the oxidation taking place only as, when, and at the place where this oxygen is released from solution by the evaporation of the liquid. Also, this oxidation takes place to some degree regardless of the condition of the combustible-whether it be lump coal, coal dust, straw, wheat flour, coke, or any other combustible but, as the speed of oxidation is directly influenced by temperature, it follows that spontaneous combustion only becomes noticeable or serious in cases where the resulting heat' cannot escape as fast as it is generated.
