Research and application of coal mine risk classification method based on the impact of COVID-19

Constructing a risk classification control system in the coal mine industry can realize the forward movement of safety gateway and prevent accidents.Through the construction of a risk classification management and control system,the safety production situation of the coal mine have shown a good trend.However,since 2020,COVID-19 has spread wantonly around the world.The new coronavirus epidemic has had a broad impact on coal mine production,and the industry risk has increased significantly,reflecting that the original risk classification method needs further improvement.Therefore,a coal mine,in constructing a risk classification control system,should consider the epidemic factors and improve the content of the risk classification system.The AHP method is used to quantify the influencing factors of the epidemic,and the epidemic impact variables are introduced into the original risk classification method to construct a risk classification method under the influence of COVID-19.The research results show that the influence proportion of COVID-19 in coal mine accidents is lower than that of gas and higher than that of traditional coal mine accidents such as fire,water,roof,electromechanical,and transportation.The data results verify the importance of COVID-19 in coal mine production and provide a theoretical basis for constructing a risk classification control system in line with the actual mine production safety.
