1、摘摘要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 240 万 t/a 新井设计。城郊煤矿位于河南省永城市境内,交通便利。井田走向(东西)长约 6.6 km,倾向(南北)长约 8.9 km,井田总面积为 37.0 km2。主采煤层为 2 号煤、3 号煤,平均倾角为 6.33,煤层平均总厚为 7.13 m。井田地质条件较为简单。井田工业储量为 273.5 Mt,矿井可采储量 207.78 Mt。矿井服务年限为 61.84 a,涌水量不大,矿井正常涌水量为 400 m3/h,最大涌水量为 650 m3/h。矿井瓦斯涌出量低,为低瓦斯矿井。井田为立井两水平上下山开拓。大巷采用
2、胶带运输机运煤,辅助运输采用固定厢式矿车设备。矿井通风方式为分区式通风。矿井年工作日为 330 d,工作制度为“四六”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、设计生产能力及服务年限;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。专题部分题目是义马煤田冲击矿压综合防治技术研究与应用。主要是对国内外先进的冲击矿压综合防治技术进行分析总结。翻译部分主要内容为关于高压水射流割缝技术在软岩煤层中控制煤与瓦斯突出的应用,英文题目为:Improving the g

4、 design of Chengjiao mine.Chengjiao mine lines in West ofYongCheng in HeNan province.The traffic of road and railway is very convenience to the mine.The run of the minefield is 6.6 km,the width is about 8.9 km,well farmland total area is 37.0 2.The two and three is the main coal seam,and its dip ang
5、le is 6.33 degree.The thickness of themine is about 7.13 m in all.The proved reserves of the minefield are 273.5 million tons.Therecoverable reserves are 207.78 million tons.The designed productive capacity is 2.4 milliontons percent year,and the service life of the mine is 61.84 years.The normal fl
6、ow of the mine is400 m3percent hour and the max flow of the mine is 650 m3percent hour.The mineral well gasgushes the deal lower,for low gas mineral well.The mine is two levels in an main shaft which well location is middle deep to expand.Thecentral laneway use belt conveyor to transport coal,mining
7、 trucks are used for accessorialtransportation in the roadway.The ventilation mode of this mine is composite form.The working system“four-six”is used in the Chengjiao mine.It produced 330 d/a.This design includes ten chapters:1.An outline of the mine field geology;2.Boundary andthe reserves of mine;
8、3.The service life and working system of mine;4.development engineeringof coalfield;5.The layout of panels;6.The method used in coal mining;7.Transportation of theunderground;8.The lifting of the mine;9.The ventilation and the safety operation of the mine;10.The basic economic and technical norms.Sp
