摘　　要：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。21 coal samples of panel I and panel II in Tashan coal mine are set as the research objects.Through comparative analysis of their gas contents,adsorption constants and other parameters,results show that the fault group has obvious control effect on regional gas deposit.Gas content of panel I is low while panel II is relatively high;under the influence of igneous intrusion,coal metamorphic degree increases,and the gas adsorption ability becomes stronger;the maximum gas content area appears at the border of igneous intrusion and the normal area.The results could provide reference for the research of gas deposit law under the joint control of igneous intrusion and the fault group and gas control work.
