七台河新建二矿06Mta的新井设计VIP免费

摘要本设计为七台河新建二矿0.6Mt/a的新井设计，共有3层设计可采煤层，平均总厚度为3.6m，煤的工业片牌号为褐煤。服务年限为51a，划分二个水平开采。本设计矿井采用双立井的开拓方式，分组集中大巷及采区石门的大巷布置方式。共划分4采区，，投产工作面2个。本设计采区为一采区，石门装车式下部车场，采用分区式通风，高档普采采煤。年工作日为330天，采用“四、六”式工作制，工作面长为150m，每刀进度为0.6m，每日割六刀。提升设备为主井采用箕斗提升，副井采用罐笼提升。关键词：可采储量采煤工艺走向长壁AbstractThetaskofthisdesignistoconstructa60milliontonsfordayanthreeMingAdministration.ThisminehasthreeminableCoalSeam,anditsaveragethicknessis3.6meters,typesofcoalseamiscokingcoal.Itcanadaptfor66years,andisdividedintotwolevel.Thismineshaftisappliedtodoubleindinedshaftdevelopmentmethod;Layoutofgathinggallergandminingdistricterossheading;Thislevelisdividedinto8miningdistrictsand2workedfaces.Thisworkedfeceismiddle2workedface,ords330dayseveryyear.Adapt“four-six”worksituation,workfaceis150meterslengthofcircleis0.6meters,andtimesis6oneday.keywords：RecoverablereservesThetechnologyofcoalminingTrendgrowsarm目录摘要..........................................................................................................................IAbstract.......................................................................................................................II目录......................................................................................................................III第1章井田概况及地质特征....................................................................................11.1井田概况.......................................................................................................11.1.1井田位置及范围................................................................................11.1.2交通位置............................................................................................11.1.3地形地势............................................................................................21.1.4气候....................................................................................................21.1.5河流....................................................................................................21.1.6工农业概况........................................................................................31.2地质特征....................................................................................................31.2.1矿区范围内的地层情况....................................................................32.2井田范围内和附近的主要地质构造...........................................................51.2.3煤层赋存状况及可采煤层特征........................................................51.2.4岩石性质、厚度特征........................................................................51.2.5井田内水文地质情况........................................................................51.2.6沼气、煤尘及煤的自燃性................................................................61.2.7煤质牌号及用途................................................................................61.3勘探程度及可靠性.......................................................................................6第2章井田境界、储量、服务年限.......................................................................82.1井田境界...................
