1、摘 要近年来,煤炭行业的发展势头一直很好,越来越多的人力和资金投入到了煤矿的建设和生产中。本设计就是在这样的的前提下对鹤壁煤业集团六矿进行实地考察和实习后,经过认真而详细的分析,计算后撰写的。本矿井设计采用立井多水平上下山的开拓方式,对角式通风,井底车场为梭式环行车场,由于本矿井型为大型矿井,生产能力为150万吨/年,对连续运输要求较高,主要采用皮带输送机运输。煤层倾角小于11左右,煤厚7.5m,采用综合机械化放顶煤开采工艺。关键词:立井 采区式走向长壁 放顶煤 Picking Wanted the recent years, the coal profession development t
