摘　　要：研究了岩层移动对煤层气卸压运移的影响,结果证明,覆岩关键层的破断运动对邻近层煤层气涌出的动态过程起控制作用;覆岩主关键层位置将决定下保护层可能的最大卸压高度.The impact of strata movement on the flow pattern of the pressure-relieved coal-bed methane was researched.The result showed that the breakages and movements of the overlying key strata control the dynamic process of coal-bed methane effusion on the adjacent strata,and the location of the primary key stratum will determine the maximum released height above the lower protective seam.

关 键 词：岩层移动 煤与煤层气共采 关键层 绿色开采
