曹野：铁法大平五矿180万吨/年新井设计辽宁工程技术大学毕业设计铁法大平五矿180万吨/年新井设计摘要辽宁省铁法市大平五矿煤矿是一座未建成的新型矿井，通过对其钻孔资料的详细分析，初步探明该地区煤炭工业储量超过3.1亿吨；整个井田含有两层煤，其中上层煤为厚煤层，厚度达18米。通过对其水文、地质资料的精查，最终确定在该矿区建成一座年产180万吨的大型矿井。针对该矿区煤层少、煤层厚度大、煤层间距及煤层倾角小的特点，最终采用在我国已经比较成熟的长壁开采法，采用分层分采的采煤方法；贯彻执行国家关于大型煤矿的建井方针，采用综合机械化采煤工艺。尝试采用最新的煤矿开采经验，用矸石填充采空区，使矸石基本不运出地面，生产系统大大简化，采用单轨吊辅助运输一条龙，从井口直达工作面，同时实现了综采与综掘同步发展，生产效率大幅提高的同时，重点研究高产高效矿井的开拓部署与巷道布置系统的优化，简化巷道布置，优化采区及工作面参数，对煤层采取集中开拓，集中准备、集中回采的关键技术，大幅度降低岩巷掘进率，多开煤巷，减少出矸率；既是减少污染的一项有力措施，又简化了生产系统，有利于高产高效集中化开采。关健词：长壁开采；分层分采；矸石填充；高产高效ThenewwelldesignforDapingfiveof1.8milliontonsperyearAbstractTheDapingcollieryofTiefacityofLiaoningProvinceisanew-typeminenotthathaven'tbuildup,throughdetailedtoanalyse,verifycoalcommercialreservesinthisareaexceed310toit.500milliontons;Thefieldofthewholewellcontainstwostoreysofcoal,amongthemtheupperstratacoalisthickcoalseams,thethicknessisupto18meters.Throughscrutinizingtoitshydrology,geologicalmaterials,confirmfinallythatbuildsupalarge-scaleminewhichproduces1,800,000tonsperyearonthisminingarea.Directthisminingareacoalseamlittle,coalseamthicknessheavy,littlecharacteristic,intervalofcoalseamandinclinationofcoalseamagainst,adoptminingmethods;Inhighyield,adoptandsynthesizethemechanizedcraftofmining.Trytoadoptthelatestcollierytoexploitexperience,packandadopttheemptydistrictwiththewasterock,makethewasterocknottransportthegroundbasically,theproductionsystemissimplifiedgreatly,adoptthemionorailtransportation,fromwellheaddirectlyworkingrange,realizecomprehensivetoadoptwithcomprehensivetoisitdevelopinsteptodigatthesametime,whiletheexperiencethatproductionefficiencyimprovebyawidemargin,keyresearchhighyieldhigh-efficientopen-upofminedisposewiththetunnelassigningsystematicoptimization,simplifythetunneltofixup,optimizetheexploitingfieldandworkingrangeparameter,isadoptedandconcentratesonopeningupthecoalseam,concentratepreparation,keytechnologyofconcentratingbackproduction,reducethetunnellingrateoftherocklanebyalargemargin,openmorecoallanes,reduceoutthegangu
