Abstract

On the basis of three classes hazard, that is, inherent hazard, temptable hazard and human factor, analyzed the main influencing factors of coal mine's gas explosion accident, built the index system of gas explosion risk forewarning in coal mine. The fuzzy mathematics comprehensive assessment technique was applied to establish a corresponding mathematic assessment model. The dynamic risk assessment on the gas explosion hazard of coal mine was undertaken in the model and so the dangerous grade of accident for coal mine was identified. It is convenient to adopt reasonable forewarning and pre-control measures for coal mine in time. Finally, combined with the practical situation of the five coal mining working faces of Zhongliang Mountain South Mine in Chongqing, China, carried out hazard risk forewarning assessment of coal mining working faces and validated the rationality of the risk assessment model.
