1、摘要本设计矿井为鸡西矿业集团盛和煤矿1.5Mt/a新井设计。此矿区内有四层煤全区可采,分别是23#、34-2#、48#和54#,平均总厚度8.4米。煤层工业牌号为1/3焦煤和焦煤,煤层倾角为20°,地质构造条件简单。设计井田的工业储量为169.83Mt,可采储量为123.9Mt,矿井服务年限为59年,本矿井设计采用立井开拓方案,划分三个水平,采用上山开采,一个工作面达产。采用集中布置,走向长壁后退式采煤法采煤,综合机械化回采工艺。工作面采用刮板输送机运输;区段运输平巷采用带式输送机运输;大巷采用14
2、t架线式电机车牵引,3t底卸式矿车运输,采用1.5t固定式矿车作为辅助运输。通风方式为分区抽出式通风。工作面长度为220m,年工作日为330d,提升方式采用1对16t箕斗提升,净提升时间为16h,采用〝三八〞工作制。关键词可采储量分区抽出式走向长壁由于本设计时间有限,本人的工作能力及现场经验也有限,因此在本设计中会出现一些问题,请各位专家及老师批评指正。全套图纸,加15389370679AbstractThisdesignminepitisabundantandthecoalmine1.5Mt/an
