摘　　要：以鑫顺煤矿15102瓦斯尾巷为背景,采用Flac3d数值模拟软件,对15102瓦斯尾巷支护设计进行了优化研究,通过改变原支护方案中锚杆锚索间排距提出4种优化方案,并模拟分析了各支护方案下巷道的位移及应力分布情况,最终得出方案三为最佳支护方案。In the background of Xinshun 15102 gas tail roadway,in this paper,Flac3 d numerical simulation software is used to the support design optimization of 15102 gas tail roadway. By changing the the row and line space of the bolt and cable of the original support program propose four kinds of optimization program,analysis and simulation to the displacement and stress distribution of the support programs,final results that option Ⅲ is the best support scheme.
