内容简介：

摘 要本设计包括三个部分：一般部分、专题部分和翻译部分。一般部分为开元煤矿1.8 Mt/a新井设计，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。开元煤矿位于山西省晋中市境内，井田南部有石太铁路和太旧高速公路，交通十分便利。井田走向（东西）长平均约5 km，倾向（南北）长平均约5.5 km，井田水平面积为27.5 km2。主采煤层两层，即9号和15下号煤层，平均倾角8，厚约3.78 m和1.8 m。井田地质资源/储量为220.11 Mt，工业资源/储量为217.91 Mt，可采资源/储量156.68 Mt，矿井服务年限为67.0a。井田地质条件简单。表土层平均厚度40 m；矿井正常涌水量为140 m3/h，最大涌水量为220 m3/h；煤层硬度系数f=2.3，煤质为瘦煤、贫煤；矿井相对瓦斯涌出量为6.69 m3/t，绝对瓦斯涌出量24.67m3/min，属低瓦斯矿井；煤层无自然发火倾向，为类不易自燃煤层；煤尘无爆炸危险。矿井采用双立井单水平开拓，采用中央分列式通风。一矿一面，采煤方法为走向长壁采煤法。煤炭运输采用胶带运输，辅助运输采用轨道运输。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：实行“三八”制。专题部分题目是区段煤柱的理论计算方法。 翻译部分是一篇关于致密多孔介质中气体视渗透率的有效联系的论文，英文原文题目为：Effective Correlation of Apparent Gas Permeability in Tight Porous Media。关键词：开元煤矿；立井开拓；采区布置；中央并列式；双巷布置；低瓦斯ABSTRACTThis design can be divided into three sections: general design, monographic study and translation of an academic paper.The general design is about a 1.8 Mt/a new underground mine design of kaiyuan coal mine. It contains ten chapters: 1.overview and the geographical features of the mining field; 2.boundary and reserves of the mining field; 3.working system, designed mine capacity and mine life; 4.development of mining field; 5.preparation in strip district; 6.coal mining method; 7.underground conveying; 8.mine exaltation; 9.mine ventilation and safety technology; 10.the basic technical and economic index.Kaiyuan coal mine lies in Yangquan, Shangdong province. As shitai railway and taijiu highway run across the southern part of the mining field, the traffic is very convenient. Its about 5 km on the strike and 5.5 km on the dip,with the 27.5 km2 total horizontal area. The minable coal seams of this mine are 9 and 15下 with the average thickness of 3.78 m and 1.8 m , the average dip of 8. The geological resources/reserves of this coal mine are 220.11 Mt, the proved resources/reserves are 217.91 Mt , the minable resources/reserves are 156.68 Mt, with a mine life of 67.0 years.The geological condition of the mine is relatively simple. The normal mine inflow is 140 m3/h and the maximum mine inflow is 220 m3/h. Its relative mine gas emission is 6.69 m3/t and absolute mine gas emission is 24.67m3/min, so it is a low gas mine with no coal spontaneous combustion tendency, also its a coal that has no dust explosion.This mine adopts vertical shaft development with one mining level and centralized ventilation. The adopted coal winning method is longwall mining to the dip or to the rise. The belt conveyor is applied to transport coal and track transport, is used in the auxiliary conveying. The workers work 330 days per year ,and exaltate 16 hours one day .The “three-eight” working system is applied for coal mining . The theme of the monographic study is the theoretical computing method of section coal pillar.The translated academic paper is about effective correlation of apparent gas permeability in tight porous media. Its title is that Effective Correlation of Apparent Gas Permeability in Tight Porous
