摘　　要：基于和睦山矿区水文地质情况及-300 m水仓系统巷道围岩状况,对该矿区软岩巷道进行支护作用机理探讨和变形分析,提出一套针对极软岩水仓系统巷道的支护与加固技术.支护结构的承载力验算及现场变形实测结果表明,该支护加固设计可有效控制极软岩遇水后的变形,支护效果良好.Based on the geohydrologic environment and --300 roadway adjointing rock conditions of water sump system in Hemushan mining area, this paper discusses and makes deformation analysis on the softrock roadway supporting mechanism in the area, and presents the support and reinforcement technology for the softest-rock roadway in water sump system. The bearing capacity computations of support structure and on-site deformation measured results show that the support and reinforcement design can efficaciously control the deformation of extra softrock encountering water with favourable supporting effect.
