ABSTRACT

In the process of coal mine production, with the increase of mining time and mining intensity, the mining depth of most mines continues to increase, most of which have exceeded 500m, and the coal mining environment is becoming increasingly complex. Coal and gas outburst disasters caused by in-situ stress, in-situ pressure, and complex gas storage conditions pose a greater threat to coal mine safety, coal and gas outburst suddenly and violently, resulting in more serious casualties and large economic losses. It has become the most serious disaster in the process of coal mine production. So far, people have not come to the real reason. Therefore, this paper explores the main causes of gas outburst disaster under the joint action of in-situ stress and gas. The interaction between coal and Gas Outburst under impact load is studied by means of theoretical analysis, impact dynamic experiment, and numerical simulation, to provide basis for the prevention and control of combined geo dynamic disasters of rock burst and gas outburst.
