华阳煤矿瓦斯地质规律分析

为了防治华阳煤矿9号、15号煤层的瓦斯灾害,通过对华阳煤矿瓦斯地质资料的整理,运用瓦斯地质理论,并结合煤层相关参数的现场测定和实验室测试,研究了地质构造、顶底板岩性、上覆基岩厚度、煤层埋深等地质因素对9号、15号煤层瓦斯赋存、分布规律的影响。结果表明:华阳煤矿瓦斯含量整体沿着倾斜方向按线性规律变化,受地质构造影响,煤层瓦斯含量分布呈现走向不均衡性;华阳煤矿煤层上覆基岩厚度对瓦斯的影响与煤层埋深对瓦斯的影响基本一致;华阳煤矿瓦斯含量随着煤层埋藏深度的增加而增大。

Analysis on gas geological laws in huayang mine

In order to control the gas disasters of 9#,15# coal seam,according to the collection of geological data of Huayang coal mine and combining the field measurement and laboratory test of the related parameters of coal seam,the paper researched the influence of geological structure,roof and floor lithologic,thickness of the overlying bedrock,coal seam depth and other geological factors on gas occurrence and distribution regularity of 9#,15# coal seam.The result showed that along the tilt direction,the whole gas content of Huayang coal mine changes according to the linear law.With the influence of geological structure,coal seam gas content distribution was imbalance along the trend direction.The influence of thickness of the overlying bedrock of Huayang coal mine on gas is basically the same as the influence of the coal seam depth on gas.The gas content of Huayang coal mine would be increased with the depth increased.
