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。一般部分为柴里煤矿1.2Mt/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。柴里煤矿位于藤县县煤田南部,滕州市西岗镇境内,南北长约8.66km,东西宽约5.50km,面积约29.5km2。主采煤层为3号煤,平均厚9.45m,井田地质条件简单。矿井工业储量为187.28Mt。矿井正常涌水量为280m3/h,最大涌水量为700
2、m3/h。矿井瓦斯涌出量低,为低瓦斯矿井。矿井为立井暗斜井延伸两水平开拓,大巷采用胶带输送机运煤,辅助运输采用矿车运输,矿井通风方式为中央边界式通风。一矿一面,矿井采用倾斜长壁综合机械化放顶煤开采法。矿井年工作日为330d,每天净提升时间16h。矿井工作制度采用“四六”制,三班生产、一班准备。专题部分题目是沿空留巷围岩控制技术研究。主要是对当前国内煤矿中沿空留巷现状分析和其应用的前景。翻译部分的英文题目为:StudyonCritical,ModernTechnologyforMininginGassyDeepMines。AbstractThedesignisincl
