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；10.矿井基本技术经济指标。一般部分为开滦范各庄矿2.4Mt/a新井设计。开滦范各庄矿位于河北省唐山市东北部，交通便利。井田走向（南北）长约6.87km，倾向（东西）长约3.62km，井田总面积为20.79km2。主采煤层为11号煤、12号煤，平均倾角为12°，煤层平均总厚为10.39m。井田地质条件较为简单。井田工业储量为313Mt，矿井可采储量216Mt。矿井服务年限为69.5a，矿井正常涌水量为249m3/h，最大涌水量为563m3/h。矿井瓦斯涌出量较低，为低瓦斯矿井。井田划分为三水平，第一水平标高为-350m，第二水平标高为-550m，第三水平标高为-800m，双立井开拓，主井装备箕斗，副井装备罐笼。大巷采用胶带输送机运煤，辅助运输采用1.5t厢式矿车运输。矿井通风方式为两翼对角式通风。矿井年工作日为330d，工作制度为“三八”制。专题部分题目为：煤矿瓦斯事故预防技术研究。翻译部分题目为：Optimization of soft rock engineering with particular reference to coal HYPERLINK / \l hit1 mining关键词： 新井设计； 井田开拓； 采煤方法； 锚杆支护ABSTRACTThis design consists of three parts: the general part, the special part and translated part.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 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.The general part is a new design of fangezhuang mine. fangezhuang mine lines in Northeast of Tangshan in HeBei province. The traffic of road and railway is very convenience to the mine. The geological structure of this area is simple. The Length of the minefield is 6.87 km ,the width is about 3.62km，the area is 20.79㎞2.The 11 and 12 is the main coal seam, and its dip angle is 12 degree. The thickness of the mine is about 10.39m in all. The proved reserves of the minefield are 313million tons. The recoverable reserves are 216 million tons. The designed productive capacity is 24 million tons percent year, and the service life of the mine is 69.5 years. The normal flow of the mine is 249m3 percent hour and the max flow of the mine is 563m3 percent hour, and the gas of the mine is low gaseous mine.The fi
