摘要
根据祁南煤矿82回风上山破坏实际情况,将其分为破坏较轻段、破坏较重段、整体需返修段3种类型,针对这3种情况分别提出了锚注支护方案、施工工艺并对锚注支护的参数进行了选择。经过在82回风上山的实际应用表明,锚注支护不仅能保持巷道的稳定,而且还取得了显著的经济效益。
According to the actual destroyed conditions of the No.82 air retuning upward roadway in Qinan Mine,a classification of the destroyed roadway was made and they were the lightly destroyed section,the seriously destroyed section and the overall repair section.According to the three types of the roadway,the bolt and grouting support plan and the construction technology were individually made.The selection of the support parameters was made for the roadway.The practical application results of the No.82 return a...
