摘要
在综合分析影响瓦斯突出多项瓦斯地质因素的基础上, 探讨了瓦斯突出事故树通用模型的创建方法; 并结合淮北芦岭矿的井田地质条件和瓦斯突出状况确立了相应的该矿井瓦斯突出事故树事件函数; 通过求取其最小割集的基本事件临界重要度系数最终确定了控制瓦斯突出的主导因素。该方法的成功应用可为瓦斯地质单元的划分和瓦斯突出的区域预测提供定量化依据。
Based on having generally analyzed multinomial factors including of gas and geology which can bring on the gas-outburs happening,the process of eablishing a universal FTA(fault tree analysis)model for gas-outbur is discussed,and the applying event function of Luling coal mine of Huaibei mining group has been created according to the real geological condition and the recording data of the coal mine.The weightiness coefficient of all basic events of minimal secant collections of the applying FTA model has been calculated and found,which can indicating the degree of the different control factors action to gas-outbur.The methods being applied successfully can offer quantitative basis for marking off gas-geological sections and for forecaing the happening of gas outbur.
