Study on Overpressure and Temperature Distribution Law of Mine Gateway After Mine Gas Explosion Occurred
Abstract:Based on the strong shock wave explosion of gas explosion dynamics and other related theory, according to the energy released from the gas explosion, a non-linear calculation formula was derived for the overpressure, temperature and the distance to the explosion location in the mine gateway after the mine explosion occurred. In comparison and analysis between the calculation value and the test val- ue, the attenuation law of the shock wave after the mine gas explosion occurred was obtained. After the mine gas explosion occurred, with the propagation distance increased, both the overpressure and the temperature would steadily decreased.
