The Application on Risk Evaluation of Gas Explosion in Heading Face Based on Unascertained Measurement Model

Abstract:

Article Preview

According to influence factors of heading face gas explosion in coal mine, selection principle based on evaluation indexes, combined with Coal mine safety regulations, Technical standards for gas extraction and experts advice, the multilevel evaluation sets of gas explosion risk in heading face was established, and the weight of each evaluation factors was determined by information entrop, finally, a coal mine was evaluated by using the unascertained measure evaluation model we had established, then security level of the coal mine was achieved. The results showed the unascertained mathematical theory was applied on comprehensive evaluation of the gas prevention and control in mine heading face, it had important significance to prevent the occurrence of gas explosions and other accidents in heading face.
