摘要
动压巷道由于承受二次采动矿压,巷道矿压显现剧烈、变形严重,给巷道的维护带来了极大困难。文章针对阳泉矿区瓦斯尾巷,采用理论分析、正交试验及FLAC数值模拟计算的方法研究二次动压巷道锚杆支护参数优化设计问题,得出最佳的支护参数,以更好地维护动压巷道。
Due to be influenced by the second mining pressure,the strata behavior is very strenuous,serious deformation,and leads difficulty in roadway maintenance.Aimming at the gas tail roadway of Yangquan mining area,by using theoretical analysis,orthogonal test and the FLAC numerical simulation calculation,the problem of supportting parameter optimization of mining induced roadway is studied,the best support parameters to support the mining induced roadway are obtained.
