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。一般部分为平朔三号井工矿6.0Mt/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。平朔三号井工矿(安太堡井工矿)位于平朔矿区的西北部,朔州市西北约28km处,井坪镇东北约6km处,行政区划隶属于山西省朔州市平鲁区管辖。井田南北宽4.76.6km,东西长7.9km,面积约28.5km2。主采煤层为4号煤、9号煤和11号煤,4号煤平均厚11.7m,9号
2、煤平均厚12.5m,11号煤平均厚3.3m,井田地质条件简单。矿井工业储量为648.73Mt,可采储量440.75Mt。矿井正常涌水量为500m3/h,最大涌水量为800m3/h。矿井瓦斯涌出量低,为低瓦斯矿井。矿井为斜井单水平开拓,大巷采用胶带输送机运煤,辅助运输采用无轨胶轮车,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“三八”制,两班生产、一班准备。专题部分题目是坚硬厚煤层综放开采顶煤弱化技术研究。主要是对当前国内煤矿中综放工作面坚硬顶煤的弱化技术进行分析。翻译部分主要内容为对千
3、万吨级矿井综采工作面的开采工艺性评价,英文题目为:Fuzzy evaluation on coal seam geological condition of coal face in ten million ton Mine。- 26 -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 Pingshuo No.3 mine. This de
4、sign 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
5、 lifting system of the mine. 9. The ventilation and the safety operation of the mine. 10. The basic economic and technical norms.Pingshuo No.3 mine lies in Northwest of Pingshuo mine The run of the mine field is 4.76.6 km,the width is about 7.9 km,mine farmland total area is 28.5 km 2. The four nine
6、 and eleven is the main coal seam,The thickness of the three main coal is about 11.7m、12.5m and 3.3m respectively. The coalfield geological condition is simple.The proved reserves of the coalfield are 648.73 million tons. The recoverable reserves are 440.75 million tons. The normal flow of the mine
7、is 500 m3 percent hour and the max flow of the mine is 800 m3 percent hour. 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 “three-eight”
