Coal and gas outburst in coal mines have seriously affected the normal production and the personal safety of workers. When coal and gas outburst can not be totally eliminated because the mechanism of outburst has not achieved major breakthrough, the researching of suppression technique in coal and gas outburst accident is important and useful. Among the coal and gas outburst accidents occurred in the coal mining production process, driving face has the highest frequency of occurrence and the largest damages, and is easily leading to catastrophe accidents such as adverse wind and so on. Based on the mechanism of coal and gas outburst disaster and destruction, the article scientifically analyzes the causes of the gas disaster and the law. The research designed for coal and gas outburst suppression technology in driving workings, can reduce the damage on the driving workings and restrain the effect of gas flow and the shock wave on the ventilation system, so as to enhance production and the ability of the ventilation system against catastrophe. Numerical simulation and the actual test play a good effect on lowering coal and gas outburst damage intensity and suppressing the occurrence of catastrophe.
