永煤集团城郊煤矿00万ta新井设计-毕业设计说明书.docx

摘 要本设计包括两个部分：一般部分、专题部分。一般部分为永煤集团城郊煤矿300万t/a新井设计。全篇共分为十个部分：矿井概况及井田地质特征、井田境界及储量、矿井工作制度、设计生产能力、井田开拓、矿井基本巷道、采煤方法、采区巷道布置、井下运输、矿井提升、矿井通风与安全和矿井主要经济技术指标。城郊矿位于河南省永城市境内。井田东西走向平均长11.2km，南北平均宽5.6km，面积约63km2。井田内可采煤层为二2煤，其赋存稳定，厚度平均为3.5 m，倾角平均6.18°，为缓倾斜煤层。井田内工业储量为3.137亿t，可采储量为2.491亿t。矿井平均涌水量为180～250 m3/d，井田中各煤层沼气含量一般小于0.5cm3/g，属低沼气矿井。各煤层均无煤尘爆炸危险。各煤层均属不自燃发火煤层；地温29～30℃。城郊煤矿年设计生产能力为300万t/a，服务年限为64年。采用立井开拓，暗斜井延深的开拓方式。工作制度为“四六”制。水平标高为－800m。矿井采用倾斜长壁综合机械化采煤法，一次采全高。矿井布置两个综采工作面，面长277m。煤炭通过胶带输送机运输。矿井初期通风方式为中央并列式。专题部分：专题题目为：煤矿“三废”的再利用研究。主要分析了 “三废”现状，作用，存在问题及解决办法，并从受力等方面对其进行了分析。关键词：立井；带区；无轨运输；中央并列式ABSTRACTThis design containstwo parts: the general and the special subject.The general part is a new design of Chengjiao Mine in Yongcheng coal electricity combine. The whole article is divided into ten parts:the outline of the mine, the mine field geology,the boundary and reserves, the designed productive capacity, theservice life and working area, the coal transportation,the mine lifting,the ventilation and safety, and the main economical and technological index of the mine.The ChengjiaoMine field lies inYongcheng in Henan province. The boundary of the mine field runs11.2km from north to south and 5.6km from west to east on average. The total planearea of the mine is about63km2.There is only one exploring layer--number two.Its average thickness of the seam is 3.5m. Its dip angle is 6.18 degree on average.The industry reserves of the mine field are 313.7 million tons and the useable reserves are 249.1 million tons. The average inflow rate in Chengjiao mine is 180~250 m3/h. It is a lower gassy mine. The coal dust doesn’t have explosion hazard as well as the self-combustion tendency. The productive capacity of Chengjiao Mine is 3.0 million tons per year，and the service life is 64years. The work system is 4-shift with a 6-hour workday. There’re two working levels in the mine. The development level is located at the -800m.The comprehensive mechanized longwall caving method along the dip is used in C
