1、摘要本设计新井为双鸭山矿业集团东荣四矿1.2Mt/a的新井设计,共有3层设计可采煤层,平均总厚度为9m。设计井田的工业储量为177.8Mt。服务年限为73.2a。划分三个水平开采。井田平均走向长5500m,平均倾斜长2800m,煤层平均倾角13°,属于缓倾斜煤层。本设计矿井采用双立井多水平开拓方式,水平共划分6个采区,其中达产采区1个,达产工作面1个。采用分组集中大巷布置方式,大巷采用10t架线电机车牵引3t底卸式矿车运输。辅助运输采用1.5t固定式矿车.本设计采区为荣二上,大巷装车式下部车场,综合机械化采煤。年工作日为330天,采用“四
2、、六”式工作制,工作面长为195m,每刀进度为0.6m,每日割九刀。采用走向长壁后退式采煤法。提升设备为主井采用两对12t箕斗提升,副井采用刚性罐笼提升。矿井的通风方式为中央边界抽出式关键词:综合机械化采煤工艺走向长壁采煤法全套图纸,加15389370651AbstractThetaskofminedesignistoconstructa1.2milliontonsnewshaftforShuangyashanMineAdministration.ThisminehasthreeminableCoalSeam,anditsaveraget
