Application of Fault Tree Analysis in the Accident of Coal and Gas Outburst
The coal and gas outburst is a kind of complicated motive power phenomenon in course of mining. It is difficult to forecast and control. Based on fault tree analysis and combining with the actual conditions of Jiu Lishan coal mine, we take coal and gas outburst as top event, consider16 root events, set up an integrated fault tree. Through analyzing, we get 80 minimal cut sets and 4 least path sets, calculate ones own importance degree, find out the main incipient fault of coal and gas outburst, quality and quantify evaluate these reasons which impact on coal and gas outburst accident, and find out the countermeasures and methods of preventing from the coal and gas outburst accident. The fault tree analysis has intuited, easy to understand, flexible characteristics. It can offer a new scientific and feasible method for appraisal of the coal and gas outburst.
