Practice and analysis of mine anti-wind exercise

Starting from the problems exposed in the process of anti-wind exercise in low gas mine, such as large-area over limit alarm of multiple mining faces, long over limit time of the excavation face, and failure to reach the time of anti-wind exercise, the influence of main ventilator types on mine anti-wind, the influence of development system on forwarding ventilation and anti-wind ventilation, the risk of anti-wind in high gas mines and coal and gas outburst mines, and the risks of anti-wind in multi-shaft mines are analyzed. It pointed out that there are institutional deficiencies in departmental regulations and industry standards, as well as the requirements for anti-wind exercises, air volume, and gas concentration control. Suggestions were proposed such as establishing a review mechanism of anti-wind exercise, standardizing the management of anti-wind exercise facilities, encouraging enterprises to formulate anti-wind exercise enterprise standards, including relevant provisions of national science and technology research plans, and revising departmental regulations and industry standards.
