1、摘 要本设计的井田面积为6.4平方千米,年产量60万吨。井田内煤层赋存比较稳定,煤层倾角10,平均煤厚7.22m,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。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,该矿井决定采用立井加暗斜井二水平开采,设计采用爆破放顶煤采煤回采工艺,倾斜长壁采煤法,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
2、产高效矿井从而达到良好的经济效益和社会效益。关键词:立井、倾斜长壁、爆破放顶煤采煤、全部垮落法、高产高效AbstractThis design well field area is6.4 square kilometers, the annualoutput 600,000 tons.
