摘要
针对西石门铁矿北采区深部巷道围岩破坏严重的情况,通过支护参数预算及正交实验设计,并采用FLAC3d软件进行模拟计算,最后使用灰色关联分析法对各项指标进行优化,从而得到最为经济、有效的支护方案。
Aiming to solve the problem that the wall rock of deep roadway in Xishimen Iron Ore northern mining area is severely damaged,by the preliminary calculation of support parameter and the orthogonal test design,it applies the FLAC3d software to conduct the analog computation and finally uses the gray relative analysis method to optimize each index.Then the most economical and effective support scheme is obtained.
