In order to effectively prevent coal mine accidents, we selected the most serious type of accident in coal mines—gas explosions—as the research object. Based on the accident causation model (24Model), we propose an action path and analysis steps of accidents caused by different employees in the organization. A gas explosion coal mine accident was analyzed using the 24Model and the proposed action path, and 12 unsafe actions, 3 unsafe states, 4 habitual behaviors, 10 safety management systems, and 10 safety cultures were obtained. Case analysis results show that by using the 24Model and path analysis the proposed effect can help employees to clearly identify the cause of the accident, to better understand the logical relationship with the causes of the accident, improve the effectiveness of training, and effectively prevent similar accidents. The 24Model and the proposed path can be used to comprehensively analyze the reasons for and help to effectively prevent coal mine gas explosion accidents.

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.
