1、 I 摘摘 要要 本次设计题目是开滦集团东欢坨煤矿 120 万吨/年开采设计,矿井井田面积 12.1km2, 煤层厚度 1.4710.46m, 平均 4.10m, 煤层厚度变化小。 煤层倾角 12 14 。设计储量为 6377.02 万吨,设计井型年产 120 万吨,服务年限为 41 年。 设计采用立井开拓,全矿划分两个阶段四个采区,布置主运输大巷和采区上 下山巷道贯通全矿井。采用走向长壁采煤法,综合机械化开采。全矿布置一个综 采工作面,选用 MG200/500QWD 型采煤机。由型号为型号为 SSJ1200/2200 的可伸缩胶带运输机运至轨道上山, 经矿车由轨道上山和主要运输大巷运至主井
2、井底车场,由箕斗提升至地面。矿井通风采用中央边界式通风方式,抽出式通风 方法,掘进面采用局扇通风,矿井总风量为 110m/s。井下多级水泵扬水排水配 合自然排水的排水方式。地下涌水经处理后供给井下用水,其余排到地面。矿区 的环境保护及职业与安全卫生也是现代矿井所要求的重点工作之一。 设计完成说明书 85 页,图纸 9 张。 关键词:关键词:开拓、采煤方法、综合机械化开采 II Alternative Title Donghuantuo Coal Mine Design Abstract This design topic is the group of Donghuantuo Coal Min
