特别重大瓦斯爆炸事故致因机制研究

Study on causation mechanism of extraordinary serious gas explosion accidents in coal mines

为了深入研究特别重大瓦斯爆炸事故演化机制问题,运用统计分析法归纳出一般瓦斯爆炸事故的核心条件、差异条件和扩大条件,通过分析三者之间的相互作用关系,建立特别重大瓦斯爆炸事故致因机制模型。研究结果表明:特别重大瓦斯爆炸事故通常以一般瓦斯爆炸事故的核心条件为基础,通过差异条件和扩大条件共同作用,最终发展成为特别重大事故。为预防特别重大瓦斯爆炸事故,应该注重调整国家的法律法规完善和煤炭产业政策,煤炭企业应该侧重人-机-环-管风险预控体系建设。

To research fully the causation mechanism of extraordinary serious gas explosion accidents,the statistical analysis method was used for idenifying the core conditions,difference conditions and enlargement conditions of general gas explosion accidents. Then,evolution mechanism model was built for extraordinary serious gas explosion accidents after analyzing the relationship among the core conditions,difference conditions and enlargement conditions. The model was used to analyze the Chenjiashan accident.The results show that extraordinary serious gas explosion accidents were based on the core conditions of the general gas explosion accidents,which interact with difference condition and enlargement condition,and that the prevention of extraordinary serious gas explosion accidents requires perfecting the laws and regulations,and the enterprises to attach great importance to establishing their risk pre-control system of humanmachine-environment-management.
