摘　　要：针对东曲矿综采工作面采空区瓦斯抽放和上隅角瓦斯超限问题,通过相似材料模拟实验,分析工作面在整个回采过程中,采空区上覆顶板岩层活动特征和裂隙发育规律,确定了不同采动条件下高抽巷的合理位置参数。According to the problems of the gas drainage in goaf and gas transfinite in the angle of up corner of fully - mechanized face in Dongqu Coal Mine, similar material simulation test was carried out. Crack developing laws and activities characteristics of goaf roof rock were researched during mining process in face. Reasonable location parameters of high drainage roadway in different mining conditions were determined.
