江西煤炭科技2023年第1期图161115综放工作面下部空巷分布位置摘要：61115综放工作面为孤岛工作面且采面下方存在有废弃空巷，该空巷在采动压力作用下容易出现围岩失稳，采面在空巷上方推进时容易出现综放设备、工作人员陷入空巷内等问题。根据工作面现场情况，拟定采用空巷加固、采面调斜、空巷影响区不放煤等技术，制定采面过空巷安全措施；现场应用后，工作面在过下部空巷期间底板及综放设备始终保持稳定，采面耗时8d顺利通过下部空巷影响区，应用取得显著成果。关键词：综放开采；孤岛工作面；下部空巷；围岩加固；木垛支护中图分类号：TD823.4+9；TD823.89文献标识码：B文章编号：1006-2572（2023）01-0022-03PracticeofCrossingStressConcentrationZoneunderneathAbandonedRoadwayinFull-mechanizedIslandCoalFaceWuYongji(LiuwanColliery,ShanxiFenxiMiningIndustryGroupCo.,Ltd.,Xiaoyi,Shanxi032303)Abstract:61115fullymechanizedcoalcavingfaceisanislandfaceandthereareabandonedroadwaysundertheface.Undertheactionofminingdynamicpressure,thesurroundingrockoftheabandonedroadwaysiseasytolosestability.Whenthefaceispushedabovetheabandonedroadways,problemssuchasfullymechanizedcoalcavingequipmentandworkersfallingintotheabandonedroadwaysareeasytooccur.Accordingtothesiteconditionsoftheworkingface,itisproposedtoadopttechnologiessuchasabandonedroadwaysreinforcement,faceslopeadjustment,nocoalcavingintheaffectedareaoftheabandonedroadways,toformulatesafetymeasuresfortheabandonedroadwayscrossing,whosefieldapplicationshowsthatthefloorandfullymechanizedcavingequipmentoftheworkingfacearealwaysstablewhencrossingtheunderneathabandonedroadway,ittakes8daystosuccessfullycrosstheaffectedareaoftheunderneathabandonedroadway,andachievesremarkableresults.Keywords:full-mechanizedcavingmining;islandcoalface;underneathabandonedroadway;surroundingrockreinforce;woodcribsupport综放孤岛工作面过应力集中带下部空巷实践武勇吉（山西汾西矿业集团有限责任公司柳湾煤矿，山西孝义032303）空巷一般是由于开采设计变更、小煤窑无序开采等原因而遗留的废弃、无维护巷道。空巷在长时间废弃、密闭环境下往往会导致水、瓦斯等富集，且由于未维护往往出现煤壁片帮、顶板网兜等情况［1-3］。现阶段...
