Abstract: In order to prevent coal mine roof, gas explosion, coal and gas outburst and water damage accidents, the unsafe acts of 100 coal mine accidents were analyzed by 2-4 Model, then the risk assessment model of coal miners' unsafe behavior based on Monte Carlo method was established. The risk value of accident behavior and the influence degree of unsafe acts on behavioral risks in each type of accident are studied, and accident prevention measures based on individual behavior level are proposed. The results shows that the risk of gas explosion accidents is the biggest, followed by coal and gas outburst, water damage, and roof accidents. In addition, three kinds of unsafe acts have a great impact on the risk of coal mine accident behavior, including "not effective water exploration", "violation of regulations in construction and production" and "giving instructions against rules and regulations".

Key words: Monte Carlo method, coal miner, unsafe acts, risk assessment, 2-4 Model
