通过对塔山矿一、二盘区21个煤样的瓦斯含量、吸附常数等参数进行对比分析,结果表明:断层群对区域瓦斯赋存有明显的控制作用,导致一盘区瓦斯含量较低,二盘区瓦斯含量较高;在火成岩的影响下,煤的变质程度增大,吸附瓦斯的能力强;瓦斯含量最大值出现在火成岩侵入边界附近。研究结果可以为火成岩和断层群联合控制作用下瓦斯赋存机理研究及瓦斯治理工作提供参考。
By comparing the gas content, adsorption constants and other parameters of 21 coal samples in the first and second panels of Tashan Mine, the results show that the fault group has significant control over the regional gas occurrence, resulting in low gas content in one plateau, Under the influence of igneous rocks, coal metamorphism degree increases, and the ability to adsorb gas is strong. The maximum of gas content appears near the invaded boundary of igneous rocks. The results of this study can provide reference for the study of gas occurrence mechanism and gas control under combined control of igneous and fault groups.
