在分析胜利煤矿地质构造演化及分布特征的基础上,结合大量的实测数据,研究矿井地质构造、顶底板岩性、煤层底板标高对瓦斯赋存的影响。对胜利煤矿瓦斯地质规律做了详细阐述,对瓦斯涌出量和煤与瓦斯区域突出危险性进行了预测。结果表明:本煤层瓦斯含量整体随埋藏深度增加而增加;断层处瓦斯赋存存在异常,特别是在断层破碎带尤为明显。
Based on the analysis of the geological evolution and distribution characteristics of Shengli Coal Mine and the large amount of measured data, the influence of mine geological structure, roof and floor lithology and seam floor elevation on gas occurrence is studied. The detailed geological gas law of Shengli Coal Mine is elaborated, and the gas emission and the prominent danger of coal and gas are predicted. The results show that the overall gas content of the coal seam increases with the increase of burial depth. The gas occurrence at the fault is abnormal, especially in the fault fracture zone.
