在收集和分析利民矿井详实地质资料的基础上,着重阐述构造地质因素对煤与瓦斯突出的控制性,不同构造部位突出危险的差异性。同时煤层围岩性质不同,地质构造发育不一样,瓦斯突出的危险性大小、地段也各异。地质构造的主要作用是形成了不同的构造应力分区,从而导致瓦斯不同程度地聚积与泄散,决定着煤与瓦斯突出的强度、密度的分区分带性。
Based on the collection and analysis of the detailed geological data of the Limin Mine, the emphases are put on the controllability of tectonic geology on the coal and gas outburst and the salient differences of different structural parts. At the same time, the surrounding rock of coal seam has different nature and different development of geological structure. The dangerous size of gas outburst and different sections also vary. The main role of geological structure is the formation of different tectonic stress zoning, resulting in different degrees of gas accumulation and drainage, determines the intensity of coal and gas outburst, the density of zonation.
