1、摘 要本设计包括三个部分：一般设计部分、专题设计部分和翻译部分。一般部分为姚桥矿5.0 Mt/a的新井设计。姚桥煤矿位于江苏省沛县和山东省微山县境内，昭阳湖西畔，距江苏省徐州市西北大约82km，距沛县县城约17km，距微山县县城约10km。区内铁路交通方便，有徐（州）沛（屯）铁路专用线，在沙塘与陇海铁路线接轨，支线直达姚桥煤矿。井田走向（东西）长平均约10 km，倾向（南北）长平均约3.5km，井田水平面积为36 km2。主采煤层一层，即7号煤层，平均倾角10，厚约9.45 m。井田工业储量为517.46Mt，可采储量393.51 Mt，矿井服务年限为60.54 a。井田地质条件简单。表土层平

2、均厚度163 m；矿井正常涌水量为325 m3/h，最大涌水量为465 m3/h；矿井瓦斯含量很低，属低瓦斯矿井；煤尘具有爆炸危险性。井田开拓方式为立井两水平上下山立井石门延深开拓。大巷采用胶带输送机运煤，辅助运输采用绞车加矿车加单轨吊运输运料。矿井通风方式前期采用中央分列式通风，后期采用两翼对角式通风。矿井年工作日为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；4、井田开拓；5、准备方式-采区巷道布置；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

3、目是深部矿井巷道稳定与支护技术研究。翻译部分是一篇关于在掘进工程中煤与瓦斯突出防治技术的研究与应用，英文原文题目为：Outburst control technology for rapid excavation in severe outburst coal关键词：姚桥煤矿；立井；两水平；上下山开采；采区布置；放顶煤；中央分列式ABSTRACTThis design can be divided into three sections: general design, monographic study and translation of an academic paper.The gen

4、eral design is about a 5.0 Mt/a new underground mine design of yaoqiao coal mine. YaoQiao coal mine is located in peixian ,jiangsu and WeiShanXian shandong province county territory, west bank zhaoyang lake, is apart from the jiangsu xuzhou northwest about 82 km, is apart from the county of about 17

5、 km peixian county, about 10 km away from WeiShanXian county. The railway traffic is convenient, xu (state) pei (the chariot) railway private sidings, sand pond and longhai railway line in international standards, regional direct YaoQiao coal mine. Its about 10 km on the strike and 3.5 km on the dip

6、,with the 36 km2 total horizontal area. The minable coal seam of this mine is only 7 with an average thickness of 9.45 m and an average dip of 10. The proved reserves of this coal mine are 517.46 Mt and the minable reserves are 393.51 Mt, with a mine life of 60.54 a.The geological condition of the m

7、ine is relatively simple. The normal mine inflow is 325 m3/h and the maximum mine inflow is 465 m3/h. The mineral well gas gushes is lower, It is a low gas mineral well and its a coal seam liable to explosion.The mine is two levels in an main shaft which well location is stonegate to expand. The cen

The mine ventilation way by the central FenLieShi, later the two wings diagonal type.The working system “three-eight” is used in the chensilou mi

9、ne. It produced 330 d/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. Transportation
