摘　　要：以某矿3_(-1)煤层为研究对象,针对该矿大断面煤层巷道支护强度过高,造成资源浪费的问题,运用FLAC^(3D) 数值模拟软件,对巷道不支护、巷道采用矿方使用方案支护、巷道采用优化方案支护3个方案进行了数值模拟研究,进而分析了3个方案的垂直应力、垂直位移、水平位移。建议采用优化后的方案3作为该煤矿回采巷道的设计方案。Focusing on No.3-1 seam of a mine, by using the FLAC3D numerical simulation software to thelarge stection mine seam roadway support strength is so high that resulting in a waste of resources problem, three schemes are designed and simulated for not support in the roadway ,using the scheme of mine support,the optimization of roadway support, vertical stress,vertical displacement,horizontal displacement are analyzed proposed to use the optimized scheme 3 as the design of the mining roadway.
