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。一般部分为平顶山一矿120万t/a新井设计。平煤一矿煤矿位于河南省平顶山西面,交通便利。井田走向(东西)长约5.27km,倾向(南北)长约5.40km,井田总面积为28.5km2。主采煤层为9号煤、22号煤,平均倾角为5,煤层平均总厚为3.80m。井田地质条件较为简单。井田工业储量为14813.3万t,矿井可采储量10193万t。矿井服务年限为65.3a,涌水量不大,矿井正常涌水量为75m3/h,最大涌水量为120m3/h。矿井瓦斯涌出量较低,为低瓦斯矿井。井田为立井两水平开拓。采用胶带运输机运煤,辅助运输采用电机车设备。矿井通风方式为中
2、央并列式通风。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、服务年限;4.井田开拓;5.准备方式-盘区巷道布置;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。专题部分题目是深井巷道围岩控制与支护技术研究。翻译部分主要内容为关于开采采空区上地表残余变形的机理与控制,英文题目为:Mechanism and control of ground residual deformation over longwall goaf。ABSTRACTThis de
3、sign includes of three parts: the general part, special subject part and translated part. The general part is a new design of PingYi mine. PingYi mine lines in West of PingDingshan in HeNan province.The traffic of road and railway is very convenience to the mine. The run of the minefield is 5.27 km
4、,the width is about 5.40 km,well farmland total area is 28.542.The nine and twenty-two is the main coal seam, and its dip angle is 5 degree. The thickness of the mine is about 3.8m in all. The proved reserves of the minefield are 148.13 million tons. The recoverable reserves are 101.93 million tons.
5、 The designed productive capacity is 1.2 million tons percent year, and the service life of the mine is 65 years. The normal flow of the mine is 75 m3 percent hour and the max flow of the mine is 120 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well.The well farml
6、and is a single level in an inclined well to expand.The working system “three-eight” is used in the PingYi 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.develop
7、ment 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 the mine; 10.The basic economic and technical norms.Special subject parts of topics is The surroun
