构造对利民矿井煤与瓦斯突出的控制

Elementary Discussion on Structure Controlling Coal & Gas Outburst in Limin Mine

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。

On the basis of collecting and analyzing detailed geological datum in Limin mine, This paper has em-phatically elaborated geology structural factors controlling coal & gas outburst, making otherness of outburst un-safety on varied structural position. Meanwhile, the country rock property of coal seam is different,there are not alike upgrowth of the geological structures. The magnitude and position of fatalness of coal & gas outburst are al-so different. The main function of geological structures has formed different structural stress blocks, thereby leading to varying on accumulation and release of gas, and resulting in blocks and zones of intensity, density of coal & gas outburst.
