1、摘 要本设计是根据河南神火集团新庄煤矿的实际情况进行的初步设计。本设计的井田面积为16.5平方千米,年产量90万吨。井田内煤层赋存比较稳定,煤层倾角510,平均煤厚2.87m,整体地质条件比较简单,在井田范围东部和中央均有断层发育。沼气和二氧化碳含量相对不高,涌水量也不大。设计采用立井一水平加暗斜井二、三水平开采的开拓方式,采用条带式准备方式,倾斜长壁采煤方法,综合机械化的回采工艺,主要对矿井开拓方式、准备方式、采煤方法进行了初步设计,对矿井运输、通风、排水等生产系统进行了设备选型计算,对矿井各个生产系统的生产过程进行了描述,并对矿井各个生产系统和各生产环节之间的相互联系和制约关系进行了有关说
2、明。在设计过程中,尽量采用先进的技术和设备,提高矿井的机械化装备水平和生产效率。关键词:立井 倾斜长壁 一次采全高 综合机械化 高产高效 AbstractThis design is the preliminary design which carries onaccording to the Henan god fire group Xinzhuang coal mine actualsituation.
