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。一般部分为赵家寨3 Mt/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。赵家寨井田位于河南省新郑市西侧,行政区划属新郑市辛店镇和城关镇及新密市大隗镇管辖。井田南北宽34km,东西长13.5km,面积约50 km2。主采煤层为二1煤。煤层平均厚度5.5m,井田地质条件简单。矿井工业储量为353Mt,可采储量244.252Mt。矿井正常涌水量为600m
2、3/h,最大涌水量为650m3/h。瓦斯相对涌出量为4.436m3/t,属于低瓦斯矿井。矿井为立井多水平开拓,大巷采用胶带输送机运煤,辅助运输采用蓄电池电机车,矿井通风方式为中央并列式通风。一矿一面,矿井采用综合机械化放顶煤开采法。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。专题部分题目是承压水上安全开采技术分析。主要是对当前国内煤矿中综放工作面承压水上安全开采技术进行分析。翻译部分主要内容为高温度燃料电池处理煤矿低浓度瓦斯,英文题目为:“Processing of coal mine gas with low methane concentr
3、ations for use in high-temperature fuel cells”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 ZhaoJiazai 300Mt coal mine. This design includes ten chapters. 1. An outline of the mine field geolo
4、gy. 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 system of the mine. 9. The ventilation and the safety op
5、eration of the mine. 10. The basic economic and technical norms.ZhaoJiazai mine lies in West of xinzheng。 The run of the mine field is 34 km,the width is about 13.5 km,mine farmland total area is 47.25 km 2. The second one is the main coal seam,The thickness of the main coal is about 5.5m respective
6、ly. The coalfield geological condition is simple.The proved reserves of the coalfield are 353 million tons. The recoverable reserves are 244.252million tons. The normal flow of the mine is 600 m3 percent hour and the max flow of the mine is 650 m3 percent hour. The mineral gas gushes the deal lower,
7、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” is used in the ZhaoJiazhai coal mine. It produced 330d/a.Special subject parts of topics is a formulation about An
