| 摘 要： | 针对大埋深软弱围岩巷道底臌防治困难等问题,以万家庄煤矿为工程背景,分析回采巷道底臌的主要影响因素,提出“锚网索+高抗框型支架”治理底臌技术,利用FlAC软件模拟在巷道掘进和回采期间的支护效果,并进行工业性试验。现场应用结果表明:顶底板相对移近量为40mm,两帮最大移近量为82mm。

| Abstract: | In view of the problems such as the difficulty of prevention and control of the roadway floor rock,taking Wanjiazhuang Coal Mine as the engineering background,this paper analyzes the main influencing factors of mining roadway bottom tension,puts forward the technology of"anchor-mesh cable+high-resistance frame support"to control the bottom tension,uses FlAC software to simulate the supporting effect during roadway excavation and mining,and carries on the industrial test.The field application results show that the relative displacement of the top and bottom plates is 40mm,and the maximum displacement of the two sides is 82mm. |
