1、WORD格式整理版摘要本设计的井田面积为3.9平方千米，年产量45万吨。井田内煤层赋存比较稳定，煤层倾角28，平均煤厚3.2m，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家暗斜井二水平开采，设计采用爆破采煤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。矿井全部实现机械化，
2、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、倾斜长壁、一次采全高、爆破采煤、高产高效学习参考好帮手WORD格式整理版学习参考好帮手WORD格式整理版AbstractThisdesignwellfieldareais3.9squarekilometers,theannualoutput450,000tons.Inthewellfieldthecoalbedtaxsavesquitestably,thecoalbedinclinationangle28,averagecoal
