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14t架线式电机车牵引，3t底卸式矿车运输
2、，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AbstractThisdesignminepitisabundantandthecoalmine1.5Mt/anewwelldesignfortheJiximiningindustrygroup.Inthism
