东欢陀矿 毕业设计
河南理工大学 2007 届本科生毕业设计（论文）1摘 要本设计年产量 60 万吨。井田内煤层赋存比较稳定煤层倾角 11-12°，平均煤厚 4.1m，整体地质条件比较简单，瓦斯涌出量相对较高，涌水量也较大。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上下山开采，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。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、高产高效河南理工大学 2007 届本科生毕业设计（论文）2AbstractAbstractThese designed yearly Output sixty trillion.
