摘　　要：以淮南矿业集团朱集矿1112(1)工作面轨道巷支护为背景,运用FLAC3D对煤巷锚杆支护进行模拟分析,提出多种支护方案。比较各种支护方案下巷道的顶板沉降、底臌及两帮位移量,综合考虑安全、支护成本、掘进进度等因素,得出一套符合煤矿生产实际的优化支护方案。Taking the track roadway support in 1112（1）working face of Zhuji Mine of Huainan Mining Industry Group as the background, using FLAC3D, this paper has conducted a simulation analysis on roadway bolting support, and put forward a variety of support schemes. After comparing roadway roof subsidence, floor heave and two sides displacement in different schemes, and considering the safety, supporting cost, excavation progress and other factors, the paper has derived a set of optimal support scheme according with the actual condition of coal production.
