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。一般部分为葛亭矿0.9Mt/a新井设计。主采煤层为3号煤,平均倾角为7.6,煤层平均总厚为6.39m。井田地质条件较为简单。井田工业储量为108.7Mt,矿井可采储量80.176Mt。矿井服务年限为51.39a,涌水量不大,矿井正常涌水量为200m3/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。井田为双立井单水平开拓。大巷采用胶带运输机运煤,辅助运输采用矿车运输。矿井通风方式为压入式通风,中央风井回风。矿井年工作日为330d,工作制度为“
2、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-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。专题部分题目是煤 与 煤 层 气 共 采 的 研 究 进 展 与 面 临 的 问 题翻译部分主要内容为关于从水力压裂资料反演地应力测定,英文题目为:In situ stress determination from inversion of hydraulic fracturing data .ABSTRACTThis design inc
3、ludes of three parts: the general part, special subject part and translated part. The designed productive capacity is0.9 million tons percent year.The three is the main coal seam, and its dip angle is 2 and 3 degree. The thickness of the mine is about 6.39 m in all. The mine Geology quality conditio
4、n is simple by Comparison.The proved reserves of the minefield are90.46 million tons.The recoverable reserves are 68.79 million tons., and the service life of the mine is 58.79 years. The normal flow of the mine is 27907m3 percent hour and the max flow of the mine is 515.5 m3 percent hour. The miner
5、al well gas gushes less than 1.285cm3/g, for low gas mineral well.All the coal seam have the danger of explor, and 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
6、 conveyance luck coal, assistance conveyance adoption mineral car.The well ventilated way of the mineral well is well ventilated for drawer type.The working system “three-eight” is used in the ChengJiao mine. It produced 330d/a.This design includes ten chapters: 1.An outline of the mine field geolog
7、y; 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. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of th
