1、摘 要 本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为夹河矿1.8Mt/a新井初步设计，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、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.矿井通风与安全技术；10.矿井基本技术经济指标。夹河煤矿位于徐州市西北九里区境内，距徐州市约11 km，地面标高+37.0+43.0 m。夹河井田东部F1号断层下盘以“徐煤局地（85）55号”文件、上盘以“苏煤基司（87）252号”文件为界与庞庄矿相邻；西部以西陇海铁路与徐州地方煤炭公司大刘矿和徐州矿务集团公

2、司义安矿为界；浅部自21煤层露头，深部至1煤层-1200 m等高线。井田走向长约4.1 km，倾向长约3.2 km，面积约13.3 km2。井田内铁路、公路均有，矿井生产的煤炭除经铁路、公路可运往全国各地外，还可经徐州港利用驳船运输，直达江浙各地，水陆交通甚为便利。铁路：西陇海铁路干线从井田西南通过，矿铁路专用线在夹河寨与西陇海干线接轨。公路：矿专用公路与徐州市三环路、徐沛公路干线和西部矿区公路连接成网。水路：井田东侧15 km左右有京杭大运河，常年可通航50 t船舶。本矿井正常涌水量120 m3/h，最大涌水量230 m3/h。瓦斯相对涌出量4.49 m3/t，绝对涌出量10.02 m3/m

3、in。整体上属于低瓦斯矿井。矿井采用立井两水平上下山开拓，采用中央并列式和边界式混合通风。一矿一面，采煤方法为长壁综采一次采全高开采。煤炭运输采用阻燃胶带运输机，辅助运输采用无轨胶轮车。矿井年工作日为330 d，每天净提升时间16 h。矿井工作制度为“三八”制。专题部分题目是浅析深井巷道支护技术。 翻译部分是一篇关于煤田开采塌陷危害的模糊综合评估的论文，英文原文题目为：The Damage Evaluation of Mining Subsidence of Coal Mining Area Based on Fuzzy Comprehensive Evaluation: A Case Stu
