摘要
依据5301运输巷与TX1、X181陷落柱间位置关系以及陷落柱内破碎岩体发育情况,对围岩支护参数进行设计。现场应用后,运输巷掘进过陷落柱期间顶板、巷帮围岩处于稳定状态,变形量最大分别为156 mm、142 mm,围岩控制效果显著。研究成果可为其他矿井回采巷道掘进过陷落柱围岩控制提供经验借鉴。
According to the positional relationship between 5301 transportation roadway and TX1 and X181 collapse columns and the development of broken rock mass in the collapse columns, the surrounding rock support parameters are designed. After field application,the roof and roadway surrounding rock are in a stable state during the driving of the transportation roadway through the collapse column,and the maximum deformation is 156 mm and 142 mm respectively. The surrounding rock control effect is remarkable. The research results can provide experience and reference for the surrounding rock control of mining roadway driving through collapse column in other mines.
