1、摘 要本设计包括三个部分:一般部分、专题部分和翻译部分。一般部分为沁新煤矿180万t/a新井设计。沁新煤矿位于山西省沁源县西部李元乡境内,交通便利。井田走向(东西)长约3.4km,倾向(南北)长约4.8km,井田总面积为16.34km2。设计开采煤层为2号煤,平均倾角为4,煤层平均总厚为3.8m。井田地质条件较为简单。井田工业储量为21603万t,矿井可采储量16663万t。矿井服务年限为66.1a,涌水量不大,矿井正常涌水量为80m3/h。矿井瓦斯涌出量不高,不是高瓦斯矿井。井田为双斜井单水平开拓。大巷采用胶带运输机运煤,辅助运输采用无极绳绞车设备。矿井通风方式为中央并列式通风。矿井年工作日
2、为330d,工作制度为“三八”制。一般部分共包括10章:1.矿区概述及井田地质特征;2.井田境界和储量;3.矿井工作制度及设计生产能力、服务年限;4.井田开拓;5.准备方式-盘区巷道布置;6.采煤方法;7.井下运输;8.矿井提升;9.矿井通风与安全技术;10.矿井基本技术经济指标。专题部分题目是沿空掘巷小煤柱稳定机理分析。翻译部分主要内容为关于煤炭开采区域关闭和水浸后后续关注和利用的策略,英文题目为:Strategies for follow-up care and utilisation of closing and flooding in Europeanhard coal mining
3、areas。ABSTRACTThis design includes of three parts: the general part, special subject part and translated part. The general part is a new design of Qinxin mine. Qinxin mine lines in West of Qinyuan in ShangXi province. The traffic of road and railway is very convenience to the mine. The run of the mi
4、nefield is 3.4 km ,the width is about 4.8 km,well farmland total area is 16.342.The two is the main coal seam, and its dip angle is 4 degree. The thickness of the mine is about 3.8m in all. The proved reserves of the minefield are 216.03 million tons. The recoverable reserves are 166.63 million tons
5、. The designed productive capacity is 1.8 million tons percent year, and the service life of the mine is 66.1 years. The normal flow of the mine is 80 m3 percent hour. The mineral well gas does not gush the deal higher.The well farmland is a single level in an inclined well to expand.The working sys
6、tem “threer-eight” is used in the Sehe mine. It produced 330d/a.This design includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.development engineering of coalfield; 5.The layout of panels; 6. The method
7、 used in coal mining; 7. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.Special subject parts of topics is stability mechanism analysis of Roadway driving along goaf small pillar .Transl
