1、 1 摘摘 要要 本设计的井田面积为 12.1 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 10-17，平均煤厚 4.10m，整体地质条件比较简单，在 井田范围西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 矿井决定采用三立井上山开采，煤层分组采区上下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施和环境保护提出要求，完成整 个矿井的初步设计。
2、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：立井 走向长壁 一次采全高 综合机械化 高产高效 2 Abstract T The well farmland area of this design is 12.1 the squares be thousand meters and the year yield is 900,000 tons.The well coal seam inside the farmland endows with to save more stable, the coa
