主立井绞车房硐室锚索注联合修复加固技术

Rockbolt cable & rockbolt grouting combined reconditioning technology applied in the winch house and winch foundation

针对谢李煤矿-312 m暗主立井绞车房硐室和绞车基础损坏情况,分析破坏原因,采取锚索锚注联合加固,用锚注充填围岩裂隙提高围岩自身承载强度,改变绞车基础共振频率;普通锚索预紧加固硐室顶板,超长锚索预紧加固绞车基础,施工速度快,费用省,成功地修复加固了受到破坏的硐室和基础。

In terms of the destroy of the winch house and winch foundation of the- 312m under-shaft in Xieli Coal Mine, the breakage causes of them are analyzed and the rockboh cable and rockboh grouting combined reconditioning technology is applied--using the method of rockboh grouting to fill the rock fissure to improve the self-bearing strength and change the resonance frequency of the winch foundation; using the common rockboh cable to tighten and reinforce the roof and using the lengthened rockboh cable to tighten and reinforce the winch foundation. After experiment the method, through which the destroyed foundation are reinforced successfully, has been proved effective in quickening the construction and saving the expenditure.
