Study on "coal and coal-bed methane simultaneous extraction" technique on the basis of strata movement

XU Jia-lin, QIAN Ming-gao,JIN Hong-wei ( School of Energy Science and Engineering,China University of Mining & Technology,Xuzhou221008,China)  
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.
