陈四楼煤矿1.5 Mt/a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。
一般部分为陈四楼1.5 Mt/a新井设计。陈四楼煤矿位于河南省永城市西北郊区,交通较为便利。井田倾向(东西)长约4.40 km,走向(南北)长约8.7km,井田总面积约为34.2 km2。主采煤层为二2号煤层,平均倾角为10°,煤层平均厚度为3.25 m。井田工业储量为160.66Mt,矿井可采储量115.67 Mt 。该矿井服务年限为59.32 a,涌水量不大,矿井正常涌水量为894 m3/h,最大涌水量为1200 m3/h。矿井瓦斯涌出量较低,为低瓦斯矿井。
根据井田地质条件,提出四个技术上可行的开拓方案。方案一:立井单水平加暗斜井开拓;方案二:立井单水平上下山开拓;方案三:立井两水平开拓(运输大巷布置在岩层中,立井直接延深);方案四:立井两水平开拓(运输大巷布置在煤层中,立井直接延深)。通过技术经济比较,最终确定方案三为最优方案。一水平标高-540 m,二水平标高-760 m。
井田为立井两水平开拓;综采一次采全高采煤法;矿井通风方式为两翼对角式。
矿井年工作日为330d,工作制度为“四六”制。
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.矿井工作制度及设计生产能力、服务年限;4.井田开拓;5.准备方式-带区巷道布置;6.采煤方法;7.井下运输;8.矿井提升;9.矿井通风与安全技术;10.矿井基本技术经济指标。
专题部分的题目为浅析煤层开采对地面桥梁的影响,主要针阐述了地表变形和对桥梁结构的影响,进而从煤层开采方面提出了一些解决措施。
翻译的内容为液压支架的静力分析和模态分析,英文题目为:The Structure Statics A
