1、 xxxx 集团石台煤矿初步设计集团石台煤矿初步设计 摘摘 要要 本设计的井田面积为 20.1 平方千米, 年产量 120 万吨。 井田内煤层 赋存比较稳定,煤层倾角 822,平均煤厚 3.48m,整体地质条件比较 简单,在井田范围南部和中央均有断层发育。瓦斯和二氧化碳含量相对 不高,涌水量也不大。根据实际的地质资料情况进行井田开拓和准备方 式的初步设计,该矿井决定采用三立井上山开采,煤层分采区上山联合 布置的开拓方式,设计采用综合机械化一次采全高回采工艺,走向长壁 采煤法,用全部跨落法处理采空区。并对矿井运输、矿井提升、矿井排 水和矿井通风等各个生产系统的设备选型计算,以及对矿井安全技术措
2、施和环境保护提出要求,完成整个矿井的初步设计。矿井全部实现机械 化,采用先进技术和借鉴已实现高产高效现代化矿井的经验,实现一矿 一面高产高效矿井从而达到良好的经济效益和社会效益。 关键词关键词:立井 、走向长壁、一次采全高、综合机械化、高产高效 AbstractAbstract These designed allotment area for 20.1 square kilometers, Yearly Output 120 trillion.
