Analysis and statistics of workers' unsafe acts in coal mine gas explosion

The literature demonstrates that nearly all of the gas explosion accidents are liability accidents. In order to get the regularity of direct causes of gas explosion, a meticulous analysis of 194 major gas explosion cases have done, and results show that there are 15 kinds of generic unsafe acts can lead to gas accumulation and can divided into 4 categories. In terms of ignition sources, we get 10 kinds of generic acts and separate into 2 categories. Statistical distribution of various generic unsafe acts are also gained: start/stop auxiliary fan optionally (19.10%) and use wrong gas emission measures (12.36%) are the 2 main generic acts lead to gas accumulation. Incorrect blasting operation process (36.72%) and hot-line work (10.17%) are the 2 main generic acts that can lead to the emergence of spark.
