1、摘摘 要要本设计包括三个部分:一般部分、专题部分和翻译部分。一般部分为桑树坪煤矿 0.9Mt/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。桑树坪煤矿位于渭北煤田韩城矿区最北端,黄河的西岸,距韩城市直距约为 35km。行政区划隶属于桑树坪镇管辖。井田南北宽 4.76.6km,东西长 7.9km,面积约 28.5km2。主采煤层为 3 号煤,平均厚 4.2m,井田地质条件简单。矿井工业储量为 648
2、.73Mt,可采储量 440.75Mt。矿井正常涌水量为 75m3/h,最大涌水量为 120m3/h。矿井瓦斯涌出量高,为高瓦斯矿井。矿井为斜井单水平开拓,大巷采用胶带输送机运煤,辅助运输采用矿车,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,两班生产、一班准备。专题部分题目是采煤沉陷地生态环境修复模式研究。主要是对当前国内采煤沉陷区生态修复做了分析。翻译部分主要内容为原位渗透性测量对建立地层岩石分层开采的影响,英文题目为:In situ permeability measuremen
