摘　　要：基于榆树井矿巷道处于极松软含水地层中,巷道围岩变形大、难以支护现状。利用FLAC3D数值模拟软件分析了巷道围岩应力重分布及变形破坏特征,并最终研究得出耦合支护对策和方案,并进行现场工业性试验和效果监测。Based on Yushujing mine roadway in the soft and water-bearing strata, in view of large surrounding rock deformation and difficult to support situation, the roadway surrounding rock stress redistribution and deformation and breakage characters were analyzed by FLAC3D numerical simulation software, and eventually come to coupling support strategies and programs, and on-site industrial test and effectiveness monitoring were implemented.
