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——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。一般部分：为郭家河煤矿7.0Mt/a新井设计。郭家河煤矿位于陕西省宝鸡市，交通便利。井田走向（东西）长约14.94 km，倾向（南北）长约7.93 km，井田总面积为88.6km2。主采煤层为三煤，倾角0~6°，平均5°。煤层平均厚度为8.5 m。井田地质条件较为简单。井田工业储量为1129Mt，矿井可采储量803.38Mt。矿井服务年限为79.6a，涌水量不大，矿井正常涌水量为1039.43 m3/h，最大涌水量为1351.26 m3/h。矿井相对瓦斯涌出量为1.29 m3/t，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：立井单水平岩巷开拓；方案二：立井单水平煤巷开拓；方案三：主斜副立单水平岩巷开拓；方案四：主斜副立单水平煤巷开拓。通过粗略和详细技术经济比较，最终确定方案一为最优方案。水平标高750m，整个井田划分为5个带区。矿井采用中央并列式通风。矿井首采区采用带区式准备方式，工作面设计长度250m，采用综合机械化放顶煤采煤工艺。矿井年工作日为330d，昼夜净提升时间为16h。矿井采用“四六”制工作制度，三班生产，一班检修。生产班每班完成3个采煤循环。循环进尺为0.80m，日产量为21212,1t。专题部分题目为浅析巷道围岩控制方法之锚注支护翻译部分题目为基于一氧化碳指标煤炭自燃倾向性试验研究关键词：立井单水平岩巷开拓；带区，中央并列式通风，综采放顶煤，ABSTRACTThe design includes three parts: the general part of the thematic part and translation partThis general part includes ten chapters: 1.An outline of the mine field geology; 2.Boundary and the reserves of mine; 3.The service life and working system of mine; 4.Development engineering of coalfield; 5. The layout of mining area; 6. The method used in coal mining; 7. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.The general part is a new design of Guojiahe mine with a production of 7.0 million t/a. mine Guojiahe lines in Baoji city, SanXi province. The traffic of road and railway is very convenience to the mine. The run of the minefield is 14.94 km ,the width is about 7.93 km, well farmland total area is 88.6 km2. No. 3 are the main coal seam, and its dip angle is 0~6°, 5° for average. The thickness of the mine are about 8.5 m. The geological conditions of the minefield is relatively simple.The proved reserve of the minefield is 1129 Mt. The designed productive capacity is 803.38Mt, and the service life of the mine is 79.6years. The normal water flow of the mine is 1039.43 m3/h and the max flow of the mine is
