本科论文设计-城郊煤矿3.0Mt-a新井设计.docx

摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。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、设计生产能力及服务年限、井田开拓、准备方式、采煤方法、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。井田南北长约12km，东西宽约11km，勘探面积约103km2。井田内可采煤层为二2煤层，其赋存稳定，平均厚度3.5m，煤层最小倾角4°，最大倾角15°，平均倾角为8°。井田内工业储量为4.4855亿t，可采储量为3.3059亿t。矿井平均涌水量为180～220 m3/h，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；地温一般低于30℃。城郊煤矿年设计生产能力为300万t/a，服务年限为78.7年。采用立井开拓，石门暗斜井延深的开拓方式。工作制度为“三八”制。第一水平标高为－500m，第二水平标高为-860m。矿井采用综合机械化采煤法，一次采全高。矿井布置两个综采工作面，面长200m。煤炭通过胶带输送机运输。矿井通风方式为分区域式通风。专题部分：专题题目为“深井软岩巷道支护原理与技术”。翻译部分：翻译题目为“巷道锚杆支护设计视为均质结构的数值方法” 。关键词：立井；暗斜井；带区；胶带运输；分区域式ABSTRACTThis design contains three parts: the general，the special subject and the translation.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, the service 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 Chengjiao Mine field lies in Yongcheng in Henan province. The boundary of the mine field runs 12km from north to south and 11km from west to east. The total area of the mine is about 103km2. There is only one exploring layer--number two. Its average thickness of the seam is 3.5m and it’s stable and flatly inclined. Its dip angle is 8 degree on average. The industry reserves of the mine field are 448.55 million tons and the useable reserves are 330.59 million tons. The average inflow rate in Chengjiao mine is 180~220 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 78.7 years. The work system is 3-shift with a 8-hour workday. There’re two working levels in the mine. The first development level is located at the -500m, and
