高瓦斯矿井沿空巷道卸压巷布置数值模拟研究
Study on Numerical Simulation of Dispose Stress-Relax Tunnel by the Gob-Side Entry in the High-Gas Mine
根据采空区侧回采巷道卸压的一般原理，针对阳泉一矿S8102工作面回风巷12m煤柱回采期间巷道围岩应力大，巷道变形严重问题，采用数值模拟软件FLAC模拟在12m煤柱靠采空区侧厚煤层的底部、中部、上部三个层位开卸压巷，分析巷道周围的塑性区分布及巷道表面位移量，从而确定合理的卸压巷布置位置，解决好回采巷道的维护问题。
Based on the general theory of stress-relax by the gob-side entry, and aimed at the Yangquan City No.1 colliery S8102 face return airway, the width of coal pillar is 12m, the entry had high stress and serious deformation , By FLAC numerical simulation, at the condition of digging the stress-relax tunnel at the base, in the central section and on the upside of the thick coal seam near the gob-side 12metre coal pillar, analysis the plastic zone distribution around the entry and the surface displacement of the entry, then conform the reasonable layer-dispose of the stress-relax tunnel, and solve the maintenance problem of the picking entry well.
