50 THE COAL TRADE BULLETIN. (CONTINUED FROM OCT. 2). EXPLOSIONS AT RUSH RUN AND RED ASH MINES, FAYETTE COUNTY, W. VA., In 1901 hoth of these mines were reported to he dusty and as early as 1897 gas was found in the Rush Run mine. On March 6, 1900, the Red Ash mine exploded and killed 46 persons. That explosion was caused primarily by the gas being ignited wliich in turn caused the dust to be inflamed which carried the explosion to all parts of the mine. In describing this disaster the writer called attention in his printed report of the danger within mines due to the very fine dust made in the mining of the eoal by machines and so far as the writer is informed this was the first public notice made of this danger incident to the use of mining machines. METEOROLOGIO (ATMOSPHERIC) CONDITIONS AFFECT ING DIST WITHIN BITUMINOUS COAL MINES.—Fine dust within coal mines is a source of much danger under several conditions: 1. In the presence of a very small percentage of explosive gas, the dust under ordinary conditions is in danger of exploding when ignited by a blast or a blown-out shot. 2. Coal dust from mines producing a soft bituminous gas or coking coal is dangerous in the absence of marsh gas or any standing or intermingled body of explosive gas. 3. The season of the year affects the condition of the dust within the mines apd is the most important factor leading up to a dust explosion. Explosions in mines in which dust has been the principal agent of destruction have, in all cases, occurred during the cold or winter months. The reasons are plainly apparent. The inside of a mine maintains a rather constant temperature throughout the year while the outside temperature has a wide range. Ordinarily a drift mine in the winter has a temperature of 55 degrees to 65 degrees while the outside temperature may be 40 degrees to 20 degrees or zero. The current of air entering the mine at 30 degrees can carry in suspension only a certain percentage of moisture, and as its temperature is increased in passing through the mine it has the faculty to hold in suspension a greater percentage of moisture which it takes from the surfaces exposed within the mine, and in time makes the mine exceedingly dry, except those places which are made wet by a supply of water. The small particles of dust are thus made to give up their moisture, held mechanically, and at once become saturated with oxygen in which condition the dust and oxygen are in an unstable condition with the other volatile and occluded gases of the dust. Under these conditions the dust will explode when flame from some source is propagated with sufficient force and temperature. Such a force may result, in a mine, from the explosion of gas, dynamite, or powder, either confined or in the open. In any event it requires a hot flame with a high initial velocity to cause the dust to explode. Experiments of technical mining commissions have proven that any dry bituminous coal dust in the absence of explosive gas can be made to explode by discharging 10 Vi ounces of dynamite so as to allow the flame of the explosion to communicate with the dust, and also that Zy2 ounces of dynamite will, under similar conditions, cause the majority of coal dusts to explode. Within the mines of this state it has been proven that the dust of the mine has propagated an explosion in non-gaseous mines caused by the blasting of the coal with powder and also by the explosion of powder confined within a powder keg. In the first instance the shot performed its work in bringing down the coal and was not a blownout or windy shot. In the second instance, as the result of a keg of powder exploding, through improper handling, a violent dust explosion extended over the greater portion of a mine and caused the death of six persons. Within the Rush Run mine, about 250 feet from the drift mouth, was standing a 16-ton electric locomotive coupled to a string of empty mine cars extending toward the mouth of the mine. Some violent explosive, such as dynamite or nitroglycerine, had been discharged between the flrst and second cars from the locomotive which literally tore to fragments these two cars, blowing the second ear toward the drift mouth and the one next to the locomotive beyond and under the locomotive. About 10 feet from the locomotive and at a point to which the end of the flrst car had extended, within the rails of the track, was found a piece of a metallic can which showed evidence of heat and it was badly twisted and had a hole blown through it. In our judgment this can contained the explosive which caused the mine to explode. How this explosive was placed there or by whom no evidence is as yet obtained. As a further precaution against the danger of dust within these mines the management of the operating company is having the mine piped for the systematic distribution of water throughout the mine. Some form of a spraying nozzle will be used in connection with hose. SUMMARY. As to violation of law which may have been the cause of this explosion, a clause of Section 10 of the mine law says: "In all mines generating firedamp, accumulations of fine dry coal dust shall as far as practicable, be prevented, and such dust shall, whenever necessary, be kept properly watered down." 1. In this particular the dust within the Rush
