摘要
在分析顺和煤矿胶带运输大巷围岩变形破坏机理的基础上,确定了修复巷道的最佳时间和二次支护方案。巷道修复后的顶板下沉量、两帮移近量、底鼓量及围岩稳定性均符合设计和使用要求。
On the basis of analyzing the surrounding rock destruction mechanism of Shunhe coal mine main haulage roadway,the best time and secondary supporting scheme to repairing roadway are determined.The roof subsidence,the deformation amount of roadway two sides,the amount of heaving floor and surrounding rock stability are in line with the design and the using requirements.
