中文摘要：

为防治瓦斯爆炸,将突变理论与模糊数学相结合的突变级数法应用在煤矿瓦斯爆炸灾难危害评价中.从人的因素,机器因素和环境因素3个角度出发,分析煤矿瓦斯爆炸的影响因素,构建瓦斯爆炸危险性评价指标体系,最后运用突变级数法对煤矿瓦斯爆炸危险性进行综合评价.以贵州木孔煤矿为评价实例,得出突变级数法的评价结果为＂一般安全＂,与实际情况一致.研究为防治瓦斯爆炸以及保障矿井的安全生产提供了一条新的思路.

英文摘要：

For prevention and control of gas explosion,this paper applies the catastrophe progression method to the coal mine gas explosion disaster risk assessment by combining catastrophe theory with fuzzy mathematics. This method analyzes the influencing factors of the gas explosion from three aspects including human,machine and environment,and builds the gas explosion hazard assessment index system. Finally,it evaluates the gas explosion hazard in the coal mines with catastrophe progression method. Taking the Mukong Coal Mine＇s gas explosion risk assessment as an example,the evaluation result of catastrophe progression method is ＂generally safe＂,and it is consistent with the reality. It has provided a new idea for the prevention of gas explosion as well as for the coal mine safety production.
