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。一般部分为丁集矿13号煤240万t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、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。丁集矿位于安徽省淮南是凤台县境内，交通便利。井田东西走向长度为1215 km，南北倾斜长度49 km，井田水平面积75.55 km2。井田内主采煤层一层，即13-1煤层，平均倾角8，煤层平均厚2.1 m，井田工业储量为216.2 Mt，可采储量206.1 Mt，

2、矿井服务年限为66.06 a。煤层硬度系数f2.3，煤质牌号为无烟煤、焦煤。本矿井为高瓦斯矿井，瓦斯绝对涌出量为13.32 m3/min。本矿井正常涌水量为480 m3/h，最大涌水量为620 m3/h。矿井采用双立井单水平开拓，前期采用中央并列式通风，后期在井田南翼设立一边界风井。由于矿井地质条件简单，且为缓倾斜煤层，所以整个矿井采用带区布置，系统简单可靠。一矿一面，采煤方法为长壁综合机械化采煤法。煤炭运输采用钢丝绳芯胶带，辅助运输采用电机车。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：实行“三八”制。专题部分题目是深井软岩巷道的支护研究。翻译部分是一篇关于在掘进工程中
