Study On The Cause Of Coal Mine Gas Explosion Accident

Coal mine accidents in the country, Gas explosion is the highest percentage of casualties, the largest losses, negative social impact of the worst coal mine accident.2005to2012coal mine gas explosion occurred nationwide from a total of284, which major, major accidents17onwards, statistics of these incidents occur, gas accumulation reached explosive concentration, the fire source and other factors, we can analyze the characteristics and laws of gas explosion accidents. The statistical classification of the factors, can be divided into individual behavior of the system, the system composition factors, environmental factors and management factors Systems4induced factor systems,20causation factors. And its system analysis, internal factors come subsystem and the relationship between different factors, application ISM model to study the relationship between the factors, come to mine gas explosion ISM model diagram, clearly reveals the most direct factor leading to coal mine gas explosion occurred, the most direct factor, the surface factors, the middle layer of factors, deep fundamental factors. Clearly reveals the most direct factor leading to the occurrence of coal mine gas explosion and surface factors, the middle layer factor, deep fundamental factors. Analytic hierarchy process to determine the weights of each factor, use of fuzzy comprehensive evaluation of the threat of coal mine accidents Zhenxiong Shawan gas explosion judge, obtained average score, In accordance with the linear relationship, calculated for each factor to reduce the effect of gas explosion threat, and sorting, what factors come improvements to reduce the threat of a gas explosion effect is obvious. Finally, based on the study of coal mine gas explosion ISM model, From the coal mine gas explosion caused by the most direct factor, the surface factors, the middle layer of factors, deep fundamental factors. of four factors, proposed coal mine gas explosion prevention countermeasures.
