Real-time numerical simulations and experimental research for the propagation characteristics of shock waves and gas flow during coal and gas outburst
Coal and gas outburst Shock wave and gas flow Propagation characteristics Cross roadway
2012/3/31
When coal and gas outburst occurs, high-speed gas flow and air shock wave with high kinetic energy could be created. In this paper, the formation process of outburst shock waves and gas flow has been ...
