金谷煤矿地表水害防治技术研究李建彪(冀中能源邢矿集团,河北邢台054400)摘要:针对水体下煤层开采中工作面突水隐患较大,生产条件复杂等问题,通过理论分析以及工程现场实践对山西古县金谷矿河流压煤开采可行性进行了研究,认为金谷煤矿满足河流压煤开采条件,通过采空区不同处理方式情况下地表移动变形值计算发现相比于全部垮落法,充填开采可减少地表移动预计值78%以上,在此基础上提出了采用压煤充填开采防治水技术方案,确保了金谷煤矿井下工作面采掘活动安全生产,为相似工程条件下地表水害防治提供了一定的理论依据与技术指导。关键词:水体下采煤;地表水害防治;充填开采中图分类号:TD745文献标志码:A文章编号:1009-0797(2023)02-0084-05ResearchonpreventionandcontroltechnologyofSurfacewaterdisasterinJinguuCoalMineLIJianbiao(JizhongEnergyXingtaiMiningGroup,Guiyang054400,China)Abstract:Aimingattheproblemsofwaterinrushhiddendangerandcomplexproductionconditionsincoalseamminingunderwaterbody,takingJinjuMineinGuxianCounty,ShanxiProvinceastheengineeringbackground,thefeasibilityofrivercoalpressingmininginJinjuMineisstudiedthroughtheoreticalanalysisandengineeringfieldpractice.ItisconcludedthatJinjuMinemeetstheminingconditionsofrivercoalpressing.Accordingtothecalculationofsurfacemovementanddeformationvalueunderdifferentgoaftreatmentmethods,itisfoundthatcomparedwiththetotalcavingmethod,fillingminingcanreducethepredictedsurfacemovementvaluebymorethan78%.Onthisbasis,thetechnicalschemeofwaterpreventionandcontrolbyfillingminingwithcoalpressingisputforwardtoensurethesafeproductionofminingactivitiesintheundergroundworkingfaceofJinguCoalMine.Itprovidesacertaintheoreticalbasisandtechnicalguidanceforthepreventionandcontrolofsurfacewaterdamageundersimilarengineeringconditions.Keywords:coalminingunderwater;controlofsurfacewaterdamage;fillingmining0引言目前我国在河流、湖泊、水库、含水层以及海下煤炭资源的开采技术逐渐趋于成熟,同时也积累了丰富的水下采煤经验[1-4]。水体下采煤所研究的主体是矿井自身,矿井自身的安全高效生产会受到来自地表水体的影响,而其影响方式主要为溃水、泥或砂以及超限涌水等,其结果往往会导致井巷遭到损坏,...
