The Solid Barrier Explosion Device of the Gas Recoil Type of the Extracting Coal Face of the Coal Mine


Article Preview

Aiming at the limitation of the roadway-type barrier explosion device which is being used in the coal mine, this paper suggests to establish the gas recoil type barrier explosion device. Using the mechanism of the gas recoil type, it made the structure design of the solid barrier explosion device of the circle-arch roadway. The device has the better effect on the elimination of the damage and the influence of the high-temperature flame of the gas and coal dust explosion and the overpressure damage of the shock wave. Especially, it can have a more realistic function for the secondary explosion or multiple explosions of the underground gas explosion.
