针对和睦山矿区软岩巷道顶板掉块、片帮、底鼓等问题,运用地质雷达无损探测、岩石力学室内试验、理论分析等研究方法,建立了和睦山矿区软岩巷道围岩综合分类表。根据软岩巷道围岩综合分类表,提出了采矿进路与穿脉运输巷支护与修复加固技术方案。
In order to solve the problems of roof fall, soft rock and kick drum in the soft rock roadway in the Mumu area, a comprehensive classification table of the surrounding rock of the soft rock roadway in the Mumu area was established by using the non-destructive detection of geologic radar, the laboratory test of rock mechanics and the theoretical analysis. According to the comprehensive classification table of surrounding rock of soft rock roadway, the technical scheme of supporting and rehabilitating and reinforcing the mining road and tandem arterial roadway is put forward.
