设计题目：袁店一矿1.8 Mt/a新井设计 专题：高渗透压松散破碎大断面失稳巷道修复技术 摘要 一般部分为淮北矿业集团袁店一矿1.8Mt/a新井设计。袁店一矿西部边界为袁店断层为界，东至32煤层-1000m的水平投影线和39467500经线，南从杨柳~五沟断层及10煤层露头线，北到32煤层-1000m的水平投影线和区块登记边界。东西长约6.9~13.6km，南北宽1.2~3.4km，井田面积约37.22km2。主采煤层为8煤和10煤，其中8煤位于10煤上部，两煤层间距平均约80m，煤层倾角为5°～15°，平均约10°，属于缓倾斜煤层，煤层平均总厚为8煤3.5m、10煤3.6m。 井田工业储量为214.47Mt，矿井可采储量148.23Mt。矿井服务年限为58.8a，第一水平服务年限28a。矿井正常涌水量为392m3/h，最大涌水量为584m3/h。矿井最大相对瓦斯涌出量10.08 m3/t，属于高瓦斯矿井。 井田开拓方式为立井两水平暗斜井延深集中岩石大巷开拓，井田采用采、带区式布置方式，共划分为三个采区，八个带区，轨道大巷、胶带机大巷和回风大巷皆为岩石大巷，布置在10#煤层底板岩层中。 针对西二采区采用了采区准备方式，共划分3个回采工作面，并进行了通风、运煤、运料、排水、排矸、供电系统设计。针对8201工作面进行了采煤工艺设计。该工作面煤层平均厚度为3.5m，平均倾角15°。矿井年工作日为330d，工作制度为“四六”制，工作面采用长壁综采一次采全高采煤法。采用双滚筒采煤机割煤，往返一次割两刀。截深1.0m，每天六个循环，循环进尺6.0m，月推进度165 m。 大巷采用胶带输送机运煤，辅助运输采用电机车牵引固定矿车运料。矿井通风方式前期为中央分列式，后期为中央并列式通风。主井采用两套带平衡锤的16t箕斗提煤，副井采用一对1.0t矿车双层四车窄罐笼和一个带平衡锤的1.0 t矿车双层四车宽罐笼运料和升降人员。 专题部分题目是高渗透压松散破碎大断面失稳巷道修复技术。 翻译部分主要内容是美国煤矿锚杆安装质量改善研究，其英文题目为：Improvi
