Application of Risk Matrix Assessment Method in Mine Safety Production

Taking a mine in Sichuan Province as the engineering background, we use risk matrix evaluation method to evaluate the safety of coal mine risk points, and according to the experience of experts and the data from risk points, we identify seven risk points in coal mine safety production. Combined with the damage value and probability value of accident risk, we get that the risk degree of mine flood is "serious"; the risk degree of mine gas, mine roof, mine collapse is "high risk"; the risk degree of mine mechanical and electrical, mine blasting, mine fire is "general risk".
