东欢坨煤矿120万吨开采设计.doc

摘 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1.47～10.46m，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MG200/500—QWD型采煤机。由型号为型号为SSJ1200/2×200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：开拓、采煤方法、综合机械化开采Alternative Title Donghuantuo Coal Mine Design Abstract This design topic is the group of Donghuantuo Coal Mine1200000tons /year of mining design, mine mine area coal seam thickness of 112km2,1.47-10.46m,4.10m, coal seam thickness change. Dip angle of coal seam12. - 14.. Design of reserves oftons, design well with an annual output of 1500000 tons, length of service for40 years. Design of mine shaft usingpioneering, divided into two stages of four mining areas, the main transportation roadway layout and mining on mine roadway. Used to long wall mining, comprehensive mechanization mining. The whole layout of a fully mechanized mining working face, using the MG200 /500- QWD type coal mining machine. A model for type SSJ1200/2 × 200telescopic belt conveyer transport to rail hill, the cars by rail hill and main transportation roadway to main shaft bottom, composed of skip hoist to the ground.Mine ventilation using the central ventilation, exhaust ventilation method, using the local fan ventilation in heading face. Downhole multi-stage pump pumping drainage combined with natural draining. Underground gushing water after treatment of underground water supply, the remaining row to the ground.
