摘　　要：结合极限平衡理论,计算选取沿空掘巷窄煤柱最小宽度,尽可能增加工作面宽度,提高资源采出率;同时利用八盘区既有大巷形成大巷煤柱工作面各生产系统。选择合理的空巷支护方案,保证采煤工作面顺利回采,确保安全生产。Combined with the limit equilibrium theory,the minimum width of narrow coal pillar in gob-side entry was calculated and selected to increase the working face width as much as possible and to improve the resource recovery rate;at the same time,the existing main roadway in eight panel area was used to form the production system of main roadway coal pillar working face.The reasonable support scheme of goaf was selected to ensure the smooth mining of coal face and the safety production.

关 键 词：采出率 大巷煤柱 沿空掘巷 窄煤柱
