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。一般部分为砂墩子矿3.0Mt/a新井设计。共分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。砂墩子位于新疆哈密市三道岭矿区后窑井田西部,北距312国道约5 km,东距三道岭矿区20 km,哈密市124 km,行政区划隶属于新疆维吾尔自治区哈密市。井田东西走向长7km,南北宽3.55.0km,井田面积约19.49km2。主采煤层为4号煤,平均厚12.55m,井田地质
2、条件简单。矿井工业储量为317.33Mt,可采储量215.48Mt。矿井正常涌水量为747m3/d,最大涌水量为1416m3/d。矿井瓦斯涌出量低,为低瓦斯矿井。矿井为立井单水平开拓,大巷采用胶带输送机运煤,辅助运输采用齿轨卡轨车,矿井通风方式为中央并列式通风。一矿一面,矿井采用倾斜长壁综合机械化放顶煤开采法,一次采全高。矿井年工作日为330d,每天净提升时间16h。矿井工作制度采用“四六”制,三班生产、一班准备。专题部分题目是浅埋深大采高工作面矿压显现规律研究。主要是对当前我国浅埋深大采高综采工作面的矿压显现规律进行分析。翻译部分主要内容为高预应力强力支护系统的发展及其在煤矿巷道中的应用,英
3、文题目为:Development of high pretensioned and intensive supporting systemand its application in coal mine roadways。关键词:立井;单水平;带区;综合机械化放顶煤;中央并列式通风ABSTRACTThe three parts are included in this design, i.e., the general part, special subject part and translated part.The general part is a new design of Sha d
4、un zi mine. 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
5、underground. 8. The lifting system of the mine. 9. The ventilation and the safety operation of the mine. 10. The basic economic and technical norms.Sha dun zi mine lies in west of San dao ling mine. The run of the mine field is about 7 km,the width is 3.55.0 km,mine farmland total area is 19.49 km 2
6、. The four is the main coal seam,Its thickness is about 12.55m. The coalfield geological condition is simple.The proved reserves of the coalfield are 317.33 million tons. The recoverable reserves are 215.48 million tons. The normal flow of the mine is 747 m3 percent day and the max flow of the mine
7、is 1416 m3 percent day. The mineral gas gushes the deal lower,for low gas mineral mine.The mine farmland in an inclined mine to expand.The main transportation uses the adhesive tape transportation opporteunity coal.The working system “four-six” is used in theSha dun zi mine. It produced 330d/a.Speci
