1、第VI页中国矿业大学2012届本科生毕业设计摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为潘三矿400 万t/a新井初步设计，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、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.矿井通风与安全技术；10.矿井基本技术经济指标。城郊矿井田位于河南省永城市境内，东南距淮南市洞山约34公里。地处凤台县城正北，相距县城15公里左右。行政区划属淮南市潘集区所管辖，井田范围地跨潘集、芦集、田集、贺疃四个乡。潘三矿濒临淮河，东起自第九勘探线与潘一矿相毗邻
2、，西至第十五勘探线和丁集勘探区相邻，矿井北部以F1断层作为与未来的潘四矿之分界线，南部以13-1煤层-900m水平的底板等高线作为深部的井境界，矿井东西走向长约9.3km，南北倾斜宽约5.8km，面积约54km2。矿区铁路专用线与阜淮线、淮南线连接，向东南经合肥至芜湖，可延伸至沪杭、皖赣线，向西约90公里经阜阳至京九线各站，公路30公里与206国道相接。水运由淮河进入长江，在淮河建有自营码头，专门从事煤炭的水运业务。煤炭主要销往淮南平圩与洛河电厂及江浙一带，交通十分便利。矿井最大涌水量为1000m3/时，正常涌水量为700 m3/时；煤质为气煤；全矿井最大绝对瓦斯涌出量为50 m3/min，属
3、高瓦斯矿井；煤层具有一定的自燃发火危险性，自然倾向性等级为级，煤尘具有一定的爆炸危险性。矿井采用立井单水平上下山开拓，采用中央并列式和两翼对角式混合通风。一矿一面，采煤方法为长壁综采一次采全高开采。煤炭运输采用阻燃胶带和底卸式矿车，辅助运输采用蓄电池电机车牵引矿车。矿井年工作日为330 d，每天净提升时间16 h。矿井工作制度为“三八”制。专题部分题目是浅析深井巷道支护技术。翻译部分是一篇关于煤与瓦斯突出矿井无人工作面开采保护层的论文，英文原文题目为：Study on mining the protective seam with the manless working face in coa
