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。一般部分为孙村矿1.8Mt/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。孙村井田位于新汶煤田的东部,其行政区划属新泰市新汶办事处境内。井田平均走向长度为7.82Km,平均倾向长度为43.62Km,井田水平面积约为43.62Km2。主采煤层为2号煤、4号煤,2号煤平均厚3.6m,4号煤平均厚2.4m,井田地质条件简单。矿井工业储量为442.274M
2、t,可采储量255.17Mt。矿井正常涌水量为154.2m3/h,最大涌水量为304.2m3/h。矿井瓦斯涌出量低,为低瓦斯矿井。矿井为两水平开拓,大巷采用胶带输送机运煤,辅助运输采用轨道矿车,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,两班班生产、一班检修。专题部分题目是沿空留巷的技术进展。主要是对当前国内沿空留巷技术的综合概述。翻译部分主要内容是高应力煤巷围岩控制机理研究与实践,英文题目为:Study on mechanism and practice of surround
3、ing rock control of high stress coal roadway.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 Suncun mine. This design includes ten chapters. 1. An outline of the mine field geology. 2. Boundary
4、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 operation of the m
5、ine. 10. The basic economic and technical norms.Suncun mine lies in Northwest of Xinwen mine. The run of the mine field is about 6.06km,the width is about 4.71 km,mine farmland total area is 28.4 km 2. The four two and four is the main coal seam,The thickness of the two main coal is about 3.6m and 2
6、.4m respectively. The coalfield geological condition is simple.The proved reserves of the coalfield are 228.7 million tons. The recoverable reserves are 173.9 million tons. The normal flow of the mine is 454.2 m3 percent hour and the max flow of the mine is 904.2 m3 percent hour. The mineral gas gus
7、hes 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 the Suncun mine. It produced 330d/a.Special subject parts of topics is a Research about
