I摘要该设计矿井为益新五矿的矿井设计，设计生产能力为2.4Mt/a，服务年限57.6a。井田共划分为18个采区开采，井田内有3层可采煤层。井田平均走向长4800m，平均倾斜长2700m，煤层平均倾角18°，属缓倾斜煤层。矿区位于鹤岗矿区东北部，距鹤岗车站6公里，行政区属鹤岗市东山区管辖。北部以煤层露头岩基为界，南邻南山煤矿和振兴煤矿，深部境界为-650标高线(面)，西邻新岭煤矿，以F1断层为界，东邻在建的鸟山煤矿，以F5断层为界。矿区的运输交通极为便利，煤炭可通过铁路运往全国。益新煤矿位于鹤岗矿区东北部，距鹤岗车站4公里，行政区属鹤岗市东山区管辖。北邻新兴煤矿,南邻南山煤矿和振兴煤矿，西邻新岭煤矿，东邻在建的鸟山煤矿。由于井田为缓倾斜煤层，以及煤层地质条件等因素影响，决定本井田内全部采用走向长壁采煤法开采。工作面全部为综合机械化采煤。顶板处理方法为全部跨落法。关键词：矿井设计综采放顶煤走向长壁采煤法IIAbstractThisdesignminepittoYixinfiveorestheminepitdesign,designproductivityis2.4Mt/a,servicelife57.6a.Thewellfieldaltogetherdivisionis9workingareamining,inthewellfieldhas3tobepossibletominecoalthelevel.Thewellfieldmovestowardlong4800mequally,mediumbanklong2700m,thecoalbedmeanobliquity18°,istheeasygradientcoalbed.TheminingarealocatedatHegangminingareanortheast,isapartfromtheHegangstation6kilometers,theadministrativeareaisHegangDongshanareajurisdiction.Thenorthappearsthebatholithtakethecoalbedas,souththeneighbourMt.Nancoalmineandpromotesthecoalmine,thedepthportionboundaryforthe-650signaltitudes(surface),westtheneighbournewrangecoalmine,taketheF1faultas,easttheneighbourthebirdmountaincoalminewhichconstructs,taketheF5faultas.Theminingareatransportationtransportationfacilitatesextremely,thecoalmaytherailwaycrossingtransporttothenation.BenefitsthenewcoalminelocatedatHegangminingareanortheast,isapartfromtheHegangstation4kilometers,theadministrativeareaisHegangDongshanareajurisdiction.Norththeneighbouremergingcoalmine,souththeneighbourMt.Nancoalmineandpromotesthecoalmine,westtheneighbournewrangecoalmine,easttheneighbourisconstructingbirdmountaincoalmine.Becausethewellfieldistheeasygradientcoalbed,aswellasfactorinfluencesandsooncoalbedgeologicalcondition,decidedthatinthiswellfieldusescompletelymovestowardlongwellminingcoallawmining.Workingsurfacecompletelyforsynthesismechanizationminingcoal.Theroofprocessingmethodtoallcrossfallthelaw.Keyword:MinepitdesignThesynthesispicksputsgoesagainstthecoalMovestowardthelongwellminingcoallawIII目录摘要............................................................IAbstract........................................................II绪论...........................................................1第1章井田概况及地质特征........................................21.1井田概况.................................................21.1.1井田位置及范围.....................................21.1.2交通位置...........................................21.1.3地形地势...........................................31.1.4气候...............................................31.1.5河流...............................................31.1.6井田区及邻区经济状况...............................31.1.7煤田开发史及近况...................................41.1.8原材料及水电供给情况...............................41.2地质特征.................................................51.2.1矿区范围内的地层情况...............................51.2.2井田范围内和附近的主要地质构造....................61.2.3煤层赋存状况及可采煤层特征.........................81.2.4井田内的水文地质情况...............................81.2.5沼气、煤尘及煤的自燃性............................101.2.6煤质、牌号及用途..................................101.3勘探程度及可靠性........................................111.3.1对地质勘探程度的评价..............................11第2章井田境界储量服务年限...................................132.1井田境界................................................132.1.1井田周边情况......................................132.1.2井田境界确定的依据................................132.1.3井田未来发展情况..................................132.2井田储量................................................132.2.1井田储量的计算....................................132.2.2保安煤柱..........................................14IV2.2.3储量计算方法......................................142.2.4储量计算的评价....................................152.3矿井工作制度生产能力服务年限........................152.3.1矿井工作制度......................................152.3.2矿井生产能力的确定................................15第3章井田开拓.................................................173.1概述....................................................173.1.1井田内外及附近生产矿井开拓方式概述...............173.1.2影响本设计矿井开拓方式的原因及其具体情况.........173.1.3确定井田开拓方式的原则............................173.2矿井开拓方案的选择......................................183.2.1井硐形式和井口位置................................183.2.2开采水平数目和标高................................203.2.3开拓巷道的布置....................................213.3选定开拓方案的系统描述..................................233.3.1井硐形式和数目....................................233.3.2井硐位置及坐标....................................233.3.3水平数目及高度....................................243.3.4石门、大巷(运输大巷、回风大巷)数目及布置.........243.3.5井底车场形式的选择................................253.3.6煤层群的联系......................................253.3.7采区划分..........................................253.4井筒布置及施工..........................................263.4.1井硐穿过的岩层性质及井硐维护.....................263.4.2井硐布置及装备....................................263.4.3井筒延伸的初步意见................................283.5井底车场及硐室..........................................283.5.1井底车场形式的确定及论证..........................283.5.2井底车场的布置存储线路行车线路布置长度..............293.5.3井底车场通过能力验算..............................303.6开采顺序...............................
