本科论文设计-开元煤矿1.2Mt-a新井设计.doc

PAGE 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1.2Mt/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）最长约4941.10km，最短约3940.95 km倾向（南北）长平均约5.5 km，井田水平面积为25.45km2。主采煤层为15下号煤层，平均倾角8°，厚约2.5m。井田地质资源/储量为114.26 Mt，工业资源/储量为113.12Mt，设计资源/储量为110.31 Mt，可采资源/储量86.98 Mt，矿井服务年限为55.77 a。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，绝对瓦斯涌出量为16.89 m3/min；煤层无自燃发火倾向，为Ш类不易自燃煤层；煤层无爆炸危险。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，采煤方法为倾斜走向长壁采煤法。煤炭运输采用钢丝绳芯胶带，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。专题部分题目是大采高综采煤壁片帮机理及控制研究。翻译部分是一篇关于矿井通风阻力与通风网络的论文，英文原文题目为：Mining subsidence- past, present, future关键词：立井开拓；采区；倾斜长壁采煤法；大采高；ABSTRACTThis design can be divided into three sections: general design, monographic study and translation of an academic paper.The general design is about a 1.2Mt/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. It’s about 4.4km on the strike and 5.5 km on the dip,with the 25.45 km2 total horizontal area. The minable coal seams of this mine is 15下 with the average thickness of 2.5 , the average dip of 8°. The geological resources/reserves of this coal mine are114.26 Mt, the proved resources/reserves are 113.12Mt Mt , the designed resources/reserves are 110.31 Mt and the minable resources/reserves are 86.98 Mt, with a mine life of 55.
