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。一般部分为东坪煤矿0.9Mt/a新井设计。主采煤层为15号煤,平均倾角为3,煤层平均总厚为3.6m。井田地质条件较为简单。井田工业储量为67.79Mt,矿井可采储量48.69Mt。矿井服务年限为41.9a,涌水量不大,矿井正常涌水量为53.3m3/h,最大涌水量为93.3m3/h。井田中各煤层瓦斯含量一般小于0.5cm3/g,属低瓦斯矿井。各煤层均无煤尘爆炸危险。各煤层均属不自燃发火煤层。井田为斜井单水平开拓。大巷采用胶带运输机运煤,辅助运输采用矿车运输。矿井通风方式为中央并列式。矿井年工作日为330d,工作制度为“三八”制。一般部分共包
2、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.准备方式带区巷道布置;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。专题部分题目是综合指数法在煤矿冲击危险性评价中的的应用翻译部分主要内容为关于应力波穿越节理时的透反射系数的研究,英文题目为:Coal Mining Under Special Conditions关键词:东坪煤矿; 斜井; 单水平; 采区与带区布置; 综合机械化采煤; ABSTRACTThis design includes of three parts: the
3、 general part, special subject part and translated part. The designed productive capacity is 0.9 million tons percent year. The fifteenth is the main coal seam, and its dip angle is 3 degree. The thickness of the mine is about 8.91m in all. The mine Geology quality condition is simple by Comparison.
4、The proved reserves of the minefield are 67.79 million tons. The recoverable reserves are 48.69 million tons. And the service life of the mine is 41.6 years. The normal flow of the mine is 53.3m3 percent hour and the max flow of the mine is 93.3m3 percent hour. The mineral well gas gushes less than
5、0.5cm3/g, for low gas mineral well. All the coal seam does not have the danger of explorer, or burn by itself.The mine farmland is a single level in an inclined well to expand. The mine farmland signs the single level of well to expand for the double. The mine lane adopts the tape conveyance luck co
6、al, assistance conveyance adoption mineral car. The well ventilated way of the mineral well is well ventilated for admixture type, expecting the central breeze well to return to breeze before, expecting to take the area breeze well to return to breeze later. The working system “four-six” is used in
7、the Chengjiao 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 used in coal mining; 7.
