显德汪矿1.5Mta新井设计
摘要
本设计包括三个部分:一般部分、专题部分和翻译部分。
一般部分共包括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;10.矿井基本技术经济指标。
一般部分为邢台显德汪矿1.5Mta新井设计。邢台显德汪矿位于河北省邢台市西南部,交通便利。井田走向(南北)长约5km,倾向(东西)长约4km,井田总面积为20km2。主采煤层为2号煤、9号煤,平均倾角为14°,煤层平均总厚为7.0m。井田地质条件较为简单。井田工业储量为148Mt,矿井可采储量105Mt。矿井服务年限为53.8a,矿井正常涌水量为140m3h,最大涌水量为200m3h。矿井瓦斯涌出量较低,为低瓦斯矿井。
井田划分为一水平和一辅助水平,第一水平标高为-50m,双立井开拓,主井装备箕斗,副井装备罐笼。大巷采用机车牵引固定矿车运煤,。矿井通风方式为前期中央并列式,后期两翼对角式通风。
矿井年工作日为330d,工作制度为“三八”制。
专题部分题目为:煤矿瓦斯事故预防技术研究。
翻译部分题目为:Effects of freque
