摘要：
Gas explosion is one type of coal mine accidents in China. The main composition of the gas in coal seam is methane, but hydrogen is contained in some coal seams and increases the risk of gas explosion. The main reaction path of methane-air mixture explosion process and elementary reactions characteristics at high temperature are analyzed using detailed mechanism of methane combustion. Different fraction of H-2/CH4/Air mixture explosion is simulated, and temperature, pressure, mole fraction of different species and elementary reactions rate are analyzed. The simulation results show that hydrogen will reduce the priming induction period of gas explosion and has influence on the temperature and pressure of gas explosion.
