依据煤与瓦斯突出综合假说和事故因果理论,提出了煤与瓦斯突出概念模型;基于FTA方法构建突出事故树基本模型。以大兴煤矿为工程实例,结合地质构造因素与突出事故树基本模型建立大兴矿突出事故树模型,通过最小割集、最小径集与结构重要度的计算来评价该矿突出路径、危害程度及防治措施,完成煤与瓦斯突出危险专项评价。
Based on the synthetic hypothesis of coal and gas outburst and the causal theory of accident, a concept model of coal and gas outburst was put forward and a basic model of incident tree was constructed based on FTA method. Taking Daxing Coal Mine as an example, the outburst accident tree model of Daxing mine was established based on the geological structural factors and the basic model of the emergent fault tree, and the salient path, hazard degree and prevention and cure of the mine were evaluated through the calculation of minimum cut set, minimum path set and structural importance Measures to complete the coal and gas outburst special assessment of the danger.
