1、本科生毕业设计说明书摘要本次设计是固阳县宝丰金矿Ⅲ号矿体开采方案设计。设计生产能力为年产量10万吨,服务年限为27年。本设计主要容包括开拓方案的选择比较、采矿方法的设计、通风系统的设计及提升与运输系统的设计等。本矿采用下盘竖井开拓,在47~55勘探线之间设计矿块。采矿方法为浅孔留矿法,阶段高度为50米,在5个阶段平面上进行巷道布置。通风系统采用中央对角式通风,主井采用单罐笼提升,两个风井布置在矿体两翼的塌陷区外,作为安全出口。排水系统采用集中排水。此外,井筒断面尺寸、石门及巷道断面尺寸、电机车的选择、矿车的选择、提升设
2、备的选择、通风设备的选择、排水设备的选择等相关容也在设计中作了相关的叙述。关键词:下盘竖井开拓;浅孔留矿法;中央对角式通风;AbstractThedesignisBaofengGuyangmininggoldorebodyNo.Ⅲprogramdesign.Theoutputofdesignedisannual100,000tons,anditslifeisservicefor27years.Thedesignincludesomecontentsasfollow:Comparingthechoicetotheprog
