摘　　要：基于某工作面开采技术条件,综合分析了卸压瓦斯抽采和防止采空区遗煤自燃对高抽巷布置层位的要求,理论确定了高抽巷需布置在回风巷侧冒落带中"O"形圈内。采用UDEC2D4.0数值模拟和物理相似模拟实验方法,分析了覆岩裂隙演化规律及移动特征。Based on the mining technology conditions at a working face, analyzed the effect of the layer parameters on the relief gas drainage and the coal spontaneous combustion in the goaf of the extrathick and easy spontaneous combustion coal seam. It was determined that the high drainage roadway is arranged in the ＂O＂ circle. Using the UEDC^2D 4.0 numerical simulation and physical similar simulation experiment method analyzed the evolution of overlying strata fissures.
