1、采矿工程毕业设计说明书摘要城山八矿生产能力1.8Mt/a新井设计，共有5层可采煤层，平均厚度为2.0m，煤的工业片牌号为1/3焦煤。设计井田的可采储量为178.08Mt，服务年限为63.99a，全矿井划分为二个水平开采。煤层平均倾角16°，井田平均走向长5590m，平均倾向长2864m。设计矿井开拓方式为双立井开拓，采用分组集中大巷布置方式。共划分6个采区，首采区投产工作面1个。设计采区为中一采区，采区下部车场采用大巷装车式，走向长壁后退式综合机械化采煤方法。年工作日为330天，采用“四、六”工

2、作制。通风方式为两翼对角式。提升设备主井采用箕斗提升，副井采用罐笼提升。关键词：可采储量走向长壁采煤方法IAbstractThetaskofthisdesignistoconstructa1.8milliontonschengziheforJixiMingAdministration.ThisminehasfourminableCoalSeam,anditsaveragethicknessis2.0meters,typesofcoalseamis1/3cokingcoal.Designedfie
