摘要
采用实验室试验、理论分析计算及数值模拟等方法,设计采用锚杆锚索联合支护方式对龙顶山煤矿1501运输顺槽进行支护,确定主要参数。现场应用后进行围岩位移监测,1501运输顺槽顶板最大下沉量为16.5mm,两帮移近量最大为15mm,取得了良好的支护效果。
By means of laboratory test,theoretical analysis and calculation,numerical simulation and other methods,the combined support method of bolt and anchor cable is designed to support the 1501 transportation channel of Longdingshan Coal Mine,and the main parameters are determined.After the field application,the displacement monitoring of surrounding rock is carried out.The maximum subsidence of the roof of the 1501 transportation channel is 16.5mm,and the maximum displacement of the two sides is 15mm,which achieved good supporting effect.
