Preventing Explosions in Mines.

Preventing Explosions in Mines.

M. Barthou, Minister of Public Works, has just witnessed a series of successful experiments to prevent explosions in mines. The tests (says a Paris dispatch) were held at a station established soon after the fatal Courrières disaster by the colliery owners of Lievin. At their conclusion M. Barthou expressed the belief that the danger from coal-dust conflagration in mines, following explosions of firedamp, could henceforth be prevented. The experiements demonstrated that certain “low temperature” or “safety explosives,” when substituted for dynamite or other hightension explosives, do not set coal-dust on fire, and, furthermore, that 40 per cent, of schist-dust, mixed with coal-dust, renders the latter free from the danger of explosion. Consequently, deposits of schist-dust at intervals in a mine will make it possible to restrict fires to a limited section of a shaft or gallery. Experiments were also conducted in chambers filled with sulphuric acid with a new respiratory apparatus and the ability of life-savers equiped therewith to work for three hours in the most noxious vapors was demonstrated.

At Muskogee, Okla., lightning struck three 1,600-barrel wooden tanks of oil and an earthen storage-tank containing 50,000 barrels, all of which were consumed. It also struck the sheriff’s home, setting it afire and partly destroying it.
