煤矿采动影响区是地面煤层气开发或井下瓦斯抽放的有利部位。基于矿井瓦斯工作实践,划分了煤矿采动影响区类型,阐述了采动影响区煤层动态含气量的数值模拟方法,并以阳煤集团二矿为例对采动影响区内煤层动态含气量进行了估算。

Infection zones of coal mining are favorable place to coalbed methane recovery in ground or gas extraction in underground.Based on gas practice of shaft,types of infection zones of coal mining were classified,numerical simulation methods of dynamic gas-content of coal seams in infection zones of coal mining were analyzed,and taking the second mine of Yangquan Coal Mine Combines as an example,dynamic gas-content of coal seams in infection zones of coal mining were evaluated.
