52 THE <strong>COAL</strong> TRADE BULLETIN. at all times while the mine was in operation or while men were within the mines. No regular flre boss was employed for night duty, to examine and report on the outside of the mine its condtion as is required by law, but there had been employed a person whose duty it was, after the men had come out of the mine in the evening, to go through the mine and examine all working places to determine if any fire had resulted from the firing of the shots, and to report any dangerous conditions found. Hollie Jarrett, who was performing this duty, lost his life on the ninth right air-course in the first explosion. A. C. Young, who came out of the mine at 8 o'clock p. m. on the night of the explosion, had been working on the 11th right entry and air-course and just before coming out had put off six blasts in the coal and had gone back and examined, the places after they had been discharged, and found no gas. In Rush Run gas was known to exist on the 11th left, the face of the main headings, and on the 9th right. After the air current had been reestablished no gas could be found anywhere within the mine with the use of a safety lamp. The 11th left heading had remained without a current of air from the time of the explosion until the 31st day of March when the writer took a sample of the air within a rubber bag and gave it a test with a Shaw gas testing machine and found it to contain 2 per cent, explosive gas. This is a quantity ten times less than can be detected with the common safety lamp and is not a dangerous quantity within itself, since it requires 5iL> per cent. of the gas with air to form an explosive mixture. The mines having been in operation on the day of the 18th of March, and the men working in the mine on that night having worked for some time that night in those places where gas had been previously reported, and the conditions of the ventilation having been good at those places as late as 6 o'clock on the evening of the 18th, as reported under oath of persons who had worked within the mine on the 18th, it devolved upon us to look elsewhere for evidence as to the primary cause or point of ignition of the explosion. Andrew Weir had taken into the mine 20 sticks of dynamite but this seems to have had no part in the explosion other than to have oeen consumed by burning. Two full sticks were found and pieces of burned wrappers of the other sticks and the sack in which this dynamite was carried was found under the two sticks and it was charred and partially consumed. It had been Weir's intention to lilast a large piece of roof rock whicli had fallen across the 11th left heading at the No. 1 room, but no evidence was found that indicated that any dynamite had been used on the fallen stone. The writer found lying on this stone a glove which could not have remained there had a charge of dynamite been exploded. Weir and Percy Wood were found on the left main intake airway at the mouth of the 11th left entry, Weir within 30 inches of the two sticks of dynamite. Weir was a contract miner and worked on the 11th left. The dust on the floor of the mine could be easily detected but it is not on the floor of the mine where all the dangerous dust is to be found. The dust within this mine becomes exceedingly fine and impalpable and collects on the sides and projections along all the headings and rooms. It is this form of dust and its position that makes the mine dangerous, and the shoveling up of the dust on the roadways only adds to the volume of this fine dust which floats away in fhe air current to find a lodging place elsewhere within the mine. The sprinkling or wetting of this dust before removal would be very beneficial. As the liability of dust to explode depends upon its degree of dryness and as this in turn is governed largely by the temperature and humidity of the air entering a mine, the danger point from this source could only be determined by observations made upon the atmosphere of the mine with an instrument such as an hygrometer which enables the percentage of moisture within the air to be determined. However, during the warm months of the year the moisture within the mine may be observed by the presence of drops of water clinging to the roof, due to what miners term "sweating." A month after the explosion the writer took observations with a hygrometer within the Rush Run mine and found the humidity of the air to be variable in different parts of the mine, and that standing bodies of water within the mine addea moisture to the air current. The condition of the mine, being very dry due to improper facilities for sprinkling with water, with respect to dust, was such as to be dangerous from a blown-out shot or a blast of dynamite. It was the practice within this mine to haul water through the mine in a water ear and with the use of a pail scatter the water on the floor of the mine at irregular intervals and at such times as was convenient to the person employed for that purpose, and as this employe had other duties to perform it is evident that the work of allaying the dust with water was with him a secondary consideration. (To BE CONTINUED). It is stated by a German mine inspector that milk of lime proves very effective in extinguishing mine fires. The emulsion, which can be used with either hand or power pumps, runs into and fills the crevices of the coal or mineral.
