济宁三号煤矿7.0Mta新井设计
摘要
本设计全篇有三个部分:一般部分、专题部分和翻译部分。
一般部分为济三矿7Mta井型设计。济三煤矿位于山东省西南部,交通便利。井田走向(东西)长约8km,倾向(南北)长约7.5km,井田总面积为55km2。主采煤层为3上、3下及16上号煤,平均倾角为4°,煤层平均总厚为10.21m。井田地质条件较为简单。井田工业储量为91954万t,矿井可采储量66020万t。矿井服务年限为72.55a。矿井涌水量较小,矿井正常涌水量为240m3h。矿井瓦斯涌出量为0.65t,为低瓦斯矿井。煤层具有自然发火倾向。
井田为立井单水平开拓,水平标高-540m。矿井采用盘区式准备方式,主运输大巷采用胶带运输机运煤,辅助运输采用无轨胶轮车设备。矿井通风方式为中央并列式通风方式。矿井采用放顶煤采煤方法,采3.6m放5.66m。
矿井年工作日为330d,工作制度为“四六”制。日循环进九刀,截深0.865m。
专题部分题目是“深部巷道变形机理及支护技术分析”。主要分析我国深部巷道在高应力的状态下所表现的变形特征,以及如何针对不同的条件选择适当的支护时机采取不同的支护方式。
翻译部分主要内容为关于破碎软岩巷道变形特征分析,英文题目为:Deformatio
