超高软岩巷道强力支护设计研究2014年第8期中州煤炭第224期超高软岩巷道强力支护设计研究王萌,张江利(山西晋煤集团技术研究院有限责任公司,山西晋城048000)摘要:以古书院矿西三盘区水仓超高软岩巷道为研究对象,应用高强度、高刚度、高可靠性与低支护密度的“三高一低”的现代锚杆支护设计理念,对巷道支护材料、支护参数进行合理选择。通过采用高预应力锚杆锚索、注浆、喷浆联合支护方式,达到了有效控制巷道围岩变形、提高围岩完整性和稳定性的目的。关键词:超高软岩巷道;数值模拟;强力支护中图分类号:TD353文献标志码:A文章编号:1003—0506(2014)08—0006—04Research011StrongSupportingDesigninSuper—highSoftRockRoadwayWangMeng,ZhangJiangli(InstituteofTechnology,ShanxiJinchengCoalGroupCo.,Ltd.,Jincheng048000,China)Abstract:Takingsuper—highsoftrockroadwayofwestern3areainGushuyuanMineasanexample,thenewboltsupportingdesigncon—ceptof”threehighandonelow”whichhasthevirtueofincludinghighstrength,highrigidity,highreliabilityandlowdensityhasbeenappliedtomakeareasonablechoiceonsupportingmaterialandsupportingparameters.Throughtheapplicationofcomprehensivesup—portingmethodscombinedwithhighpressureboltandanchor,groutingandguniting,thepurposeofcontrollingroadwaysurroundingrockdeformation,improvingtheintegrityandstabilityofsurroundingrockhavebeenachieved.Keywords:super—high
