摘要
针对西铭矿48705工作面单轨吊巷围岩控制问题,采用理论分析与数值计算方法对迎采巷道支护参数进行研究,阐述了西铭矿48705工作面单轨吊巷现有支护方式及存在的问题;通过数值分析,分析了不同巷道掘进方式围岩应力、围岩破坏情况,从不同角度方面对比分析了采用不同巷道掘进时的优缺点;最后针对西铭矿48705工作面单轨吊巷2种方案下的具体支护参数进行了设计。
Aiming at the surrounding rock control problem of 48705 working face in Ximing coal mine,the paper studies the support parameters of heading roadway by theoretical analysis and numerical calculation method,expounds the existing support methods and existing problems of monorail hanging roadway in 48705 working face of Ximing mine;through numerical analysis,it analyzes the surrounding rock stress and surrounding rock damage of different roadway driving methods,and compares and analyzes them from different angles The advantages and disadvantages of different roadways are analyzed.Finally,the supporting parameters of 48705 working face in Ximing coal mine are designed.
