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。一般部分为城郊矿1.5Mt/a新井设计。主采煤层为二2号煤、三2号煤,平均倾角为8,煤层平均总厚为8.91m。井田地质条件较为简单。井田工业储量为199.9Mt,矿井可采储量136.34Mt。矿井服务年限为63.88a,涌水量不大,矿井正常涌水量为220m3/h,最大涌水量为360m3/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。井田为立井两水平开拓。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风井回风。矿井年工作日为330d,工作制度为“三八”制。
2、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。专题部分题目是综放开采顶煤的冒放性与控制翻译部分英文题目为:Science of Complexity and Its Revelation on Study of Coal Mine Safety Behavior Problems.关键词:城郊煤矿;立井暗斜井;两水平;采区与带区布置;综采放顶煤方法; ABSTRACTThis design inc
3、ludes of three parts: the general part, special subject part and translated part. The designed productive capacity is1.5million tons percent year. The two and three 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 conditi
4、on is simple by Comparison.The proved reserves of the minefield are 199.9 million tons. The recoverable reserves are 136.34 million tons. And the service life of the mine is 63.88 years. The normal flow of the mine is 220m3 percent hour and the max flow of the mine is 360 m3 percent hour. The minera
5、l well gas gushes less than 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
6、 the tape conveyance luck coal, 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 s
7、ystem “three-eight” is used in 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.
