At your request, am submitting to you several suggestions for the amendment of our safety code which you felt should be kept up to date. These suggestions are the individual opinions of the several members of the Committee who have expressed (heir wishes to me in the form of letters. I am particularly indebted to Mr. Daniel Harrington, Mr. Wm. Littlejohn, Mr. Warren Bracewell, Mr. James Dalrymple and Mr. Hugh McLeod. Would recommend the following amendments Section 1. Wherever practical trolley wires should be securely hung to roof or timbers at a distance of not less than five feet and not more than six and one-half feet above rail and six inches to one side. Spacing of hangers should be from 20 to 25 feet apart. (Adopted.) Section 2. 500 volts D. C. should not be allowed in any installations. Trolley wires should not carry a voltage of more than 250 D. C. nominal voltage. (Referred back.) Pumps, mining machines and other small machinery units where A. C. power is used should not carry a voltage of more than 220. Large units, such as pumps, motor generator sets and hoists, may use a volt- age of 2,200. When power cables to operate same are of armored construction, cables should be securely buried at all crossings, on haulage-ways or where men travel. (Adopted.) Section. 4. Where power lines pass through door frames or stop- pings they should be properly insulated with porcelain compound or rubber tubing. Wherever men get on or off man-trips in vicinity of trolley wires same should be secure1y guarded and should also be protected with a cut- out switch, same to be pulled before men are allowed to get on or off trips. (Adopted.)

MR. DAVIS: When the Secretary asked me to continue our accident experience in safety work at Dawson to cover the year just closed, I rather felt that he was asking 'a good deal, for we had said about everything that we could last year. I am not going to say very much, but in line with his request I have merely brought the figures up to date. I want to say, to start, that 1934 was, rather disappointing. It was the poorest year since 1930, as you will notice (indicates on diagram). This first column represents the accidents per thousand shifts worked. We cannot assign any real valid reason for the increase. We think we worked just as hard, but we are rather inclined to lay it onto the times; in other words, to lay it to the unrest and the changing conditions that are existent not only in this country but probably all over the world. We had twelve lost time accidents last year. As I explained last year, a lost time accident with us is an accident wherein the injured man is not able to return to his regular work, the next day-the day following the injury. So this represents (indicating) the lost time accidents per thousand shifts worked. We had one fatality in the twelve accidents which is reflected in the severity rates, which are also based upon thousand shifts worked instead of per million hours. The reason we are on the thousand shifts worked is be¬cause the Copper Branches of the Phelps-Dodge Corporation are all kept that way, and we are on the same basis for easy comparison.

We so sign our names to this. This Auditing Committee wishes to take this opportunity to commend and thank Mrs. Whiteside for her dedicated effort in keeping the financial records of the Rocky Mountain Coal Mining Institute in such excellent order. (See page 5 for printed Treasurer's Report) Mr. White asked for a motion to approve the records, it was made, seconded and approved. Mr. Meade Harker, Chairman of the Finance Committee, was asked to give his report. He stated that the Colorado contributors total was $630.00 and the Utah $39.0.00, making a grand total of $970.00.

Safety Measures Employed at the Dawson Mines Preventive measures for eliminating and localizing explosions is a subject of special interest to Coal Mining operators at the present time. I shall endeavor in this paper to present the practical methods which have been developed at the mines of the Stag Canon Branch of the Phelps-Dodge Corporation, Dawson, New Mexico. Adobe Dusting Adobe is used for practically all dusting on the main haulage roads. It is obtainable in sufficient quantities adjacent to the mines. Loaded into railroad cars by a clam-shell loading crane, and transferred to the mine pit cars at the nearest available point, it is readily distributed along the motor roads by means of the mine locomotives. Of first consideration for adobe dusting is the preparation of the roadway. It is essential that all loose coal and dust be removed, at least to a depth of three or four inches below the top of the rails. The adobe, in a more or less moist condition is unloaded by hand from the pit cars and stored along the previously prepared roadway, to be later scattered to a depth of several inches over the floor, and over the ribs and roof such as is possible by the use of a shovel. The adobe soon loses its moisture and becomes pulverized. Due to the disturbance caused by passing motor trips, men and animals, the dust is effectively scattered along the ribs and roof of the roads. The velocity of the intake air aids materially in sustaining the suspension of this inert matter. Another scheme for distributing the fine dust in use is to chain the top of a pine tree to the rear of the trips, both empty and loaded. Dragging it along the motor roads stirs up the dust and aided by the intake air it is carried for long distances into the workings. The adobe is continually loosened and raked, all rock, coal, etc., being collected in piles and later loaded out in pit cars. One man is employed for each six thousand feet of entry. Dusting Main Return Air-Courses The air-courses are first thoroughly cleaned. All the loose coal and rock is loaded out, the ribs and roof washed down several times. Every five or six hundred feet, the stoppings between the main and return entries are broken through and small doors installed. Blowers are used to force the fine dust into the return air-courses through these openings. Thus suspended the dust travels a considerable distance before it is deposited on the floor, ribs and roof. The material used is chiefly adobe, sun dried, and screened on the outside. A two ton car load of this dust will cover several hundred feet of airway as very little loss occurs, often depositing from 2 to 6 pounds per running foot of entry. Methods of Insertion Blowers are used to force the dust into the main returns. One unit consists of a small Buffalo blower mounted on a truck with a two H. P. motor. A six-inch pipe is attached to the blower and runs the full length of the truck with a projection over the end. A hopper is built over the pipe and connected. Stove pipe or canvas tubing is led from the pipe through door in stopping. When the blower is started dust is fed into the

The Bush Administration is committed to reducing emissions from existing power plants Candidate George W. Bush said: The key to reducing emissions from older power plants on the federal level is to cap emissions on a level that makes sense?. And harness the power of the market place and provide economic incentives to produce better environmental results. I would want to make sure that any program we pursue does not result in excessive and unnecessary increases in electric bills.
