1、河南理工大学本科毕业设计煤矿毕业设计说明书_本科毕业设计摘要本设计矿井的井田面积为29.96平方千米,年产量300万吨。井田内煤层赋存比较稳定,煤层倾角,平均3°,煤层厚度平均8.0m。井田范围内整体地质条件比较简单,断层较发育,但均是小断层。矿井瓦斯含量较高,为高瓦斯矿井,矿井涌水量不大。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,该矿井决定采用双斜井两水平上下山开采,采用带区式开拓方式。设计采用综合机械化放顶煤回采工艺,倾斜长壁采煤法,用全部跨落法处理采空区,并对矿井运输、提升、排水和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
2、了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:倾斜长壁放顶煤综合机械化高产高效991河南理工大学本科毕业设计AbstractThesedesignedallotmentareafor29.96squarekilometers,YearlyOutputthree-hundredtrillion.Allotmentintrinsicallyocurrenceofcoalseamcomparestabilize,coalseampitchisunderfifteenacid,
