文档介绍:河北工程大学 1 摘要本设计的井田面积为 平方千米,年产量 90万吨。煤层赋存比较稳定, 煤层倾角平均 14°,平均煤厚 ,整体地质条件比较简单,沼气和二氧化碳含量相对较低,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,该矿井决定采用双立井单水平上下山开采,煤层采用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,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、综合机械化、高产高效河北工程大学 2 Abstract These designed allotment area for square kilometer s,Yearly Output ninty trillion.
