【 摘 要 】

In recent years, the average annual coal mine industry will occur from 6 to 7 a one-time death of more than 10 gas explosion accident, and the cause of the accident is caused by people's unsafe act, so analysing the unsafe act of the gas explosion accident is the key way to prevent this kind of accident. Based on the 24Model, this paper analyses the unsafe operation of all the major and particular major gas explosion accidents in the past 10 years, and the frequency of triggering accidents. The results show that: illegal operation occurred in a total of 24 unsafe movements, grouped into 4 categories, occurred 141 times in 63 incidents, The "Unchecked gas" act is the highest frequency of triggering accidents, the frequency of triggering accidents is 23% of all unsafe operation acts; illegal behaviour occurred in a total of 24 unsafe movements, grouped into 4 categories, frequency of 155 times, where "illegal or no placement ventilation set" appears to be the highest frequency, 15% of the total frequency ratio; a total of 28 unsafe actions in violation of command, grouped into 4 categories, the frequency is 198 times, "ultra-layer cross-border theft" is this type of unsafe action if the most times, frequency ratio is 14%. Provide scientific basis for preventing gas explosion accident in coal mine.
