江西煤炭科技2023年第1期摘要：申南凹矿8#煤层回采巷道以往采用单体柱进行超前支护，一定程度上制约了工作面的回采效率。以20108回风顺槽为工程实例，分析探讨锚索超前支护技术；综合运用理论计算、数值模拟等手段，确定超前支承压力峰值和影响范围；分析结果为超前支护范围不小于20m、锚索最佳长度5.3m、锚索“212”布置。20108回风顺槽应用新的超前支护技术后表明，超前应力影响区巷道表面变形量在合理范围内，锚索承载性能良好，支护效果显著。关键词：巷道超前支护；锚索补强；数值模拟；理论计算；支承压力中图分类号：TD82-9；TD353文献标识码：A文章编号：1006-2572（2023）01-0093-03ApplicationAnalysisofAdvancedSupportTechnologyforGatewayofNo.8CoalSeaminShennanaoCollieryRenLifeng(ShennanaoCokingCoalCo.,Ltd.,ShanxiXiangningCokingCoalGroup,Linfen,Shanxi042105)Abstract:TheminingroadwayofNo.8coalseaminShennanaoCollieryusedtousesinglepillarforadvancesupport,whichrestrictedtheminingefficiencyoftheworkingfacetoacertainextent.Taking20108returnairentryastheengineeringexample,firstly,theauthoranalyzesanddiscussestheanchorcableadvancesupporttechnology,whoseapplicationshowsthatthedeformationoftheroadwaysurfaceintheadvancedstressaffectedareaiswithinareasonablerange,thebearingcapacityoftheanchorcableisgood,andthesupporteffectisremarkable.Secondly,theauthordeterminesthepeakvalueandinfluencerangeofadvanceabutmentpressurebycomprehensiveuseoftheoreticalcalculation,numericalsimulationandothermeans,whoseresultsarethattheadvancesupportrangeisnotlessthan20m,theoptimallengthofanchorcableis5.3m,andtheanchorcablearrangementis"212".Keywords:roadwayadvancedsupport;cablesupplementsupport;numericalsimulation;theoreticalcalculation;abutmentpressure申南凹矿8#煤回采巷道超前支护技术应用分析任立峰（山西乡宁焦煤集团申南凹焦煤有限公司，山西临汾042105）1工作面概况山西乡宁焦煤集团申南凹焦煤有限公司（申南凹矿）20108综采工作面（以下简称工作面）开采2#煤层。2#煤层结构简单，煤（岩）层倾角2°～13°，工作面顺槽沿煤层走向布置，切眼沿煤层倾斜布置，顺槽及切眼均沿煤层顶板掘进成巷。工作面长度为180m，走向长度为996m，可采储量为1.14095Mt。工作面以北为201...
