胜利煤矿44~#煤层瓦斯地质规律分析

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。

Analysis on Gas Geological Law of NoA4 Seam in Shengli Mine

Based on the analysis and study on geologic tectonic evolution and distribution characteristic in Shengli mine.It studys the geological structure of the mine roof and floor of coal seam floor,lithology,and the effect of elevation on gas occurrence,combined with a large number of experimental data.Coal mine gas geology in detail,quantity of gas emission and coal and gas outburst dangerous area undertook forecasting.The results showed that generally,the gas content of the seam would be increased with the depth of the seam increased.There would be an abnormal phenomenon occurred at the deposit gas at the geological fault and especiall when the fault was in fracture zone.
