Abstract

Most of coal and gas outburst accidents in China are caused directly by human misconduct in specific circumstances, lose efficacy of gas monitoring system and storage condition changes of the coal bed. In this paper, investigation was done on each component reliability of the Man-Machine-Environment(MME) interaction system, digging device and the situation of the coal bed with its working surface. The investigation is based on the theory and method of the safety system engineering, and regard factors that may cause the outburst in the outburst prevention system. In order to devise coal and gas outburst prevention system with sufficient evidence, reliability calculation of each unit of the outburst prevention system on the working surface has been done, and the distribution and features of the reliability are analyzed based on a real case of the Wansan coal mine, Lianyuan town, Hunan province.
