1、摘 要本设计包括三部分:一般部分、专题部分和翻译部分。一般部分为王庄煤矿1.8Mt/a新井设计。王庄煤矿位于山西省长治市郊区故县,距市中心30公里,交通便利。井田走向(南北)长约11.0km,倾向(东西)长约4.5km,总面积为49.3km2。主采煤层为3#煤层,煤层倾角为25,平均厚度为4.0m。井田地质条件较为简单。井田工业储量为25714万t,可采储量为18640万t。矿井设计生产能力为1.8Mt/a。矿井服务年限为79.7a,涌水量不大,矿井正常涌水量为144 m3/ h,最大涌水量292 m3/ h。矿井瓦斯相对涌出量为1.23m3t,绝对涌出量为4.22m3min,为低瓦斯矿井。矿
2、井开拓方式为立井单水平上下山开拓。采用胶带输送机运煤,采用矿车进行辅助运输。矿井通风方式为中央并列式通风。矿井年工作日为330d,工作制度为“三八制”。一般部分共包括10章:1、矿区概述与井田地质特征;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;10、设计矿井基本技术经济指标。专题部分题目是急倾斜煤层工作面三带分布特征分析,主要是研究了急倾斜煤层顶板破坏与维护,以及急倾斜煤层条件下的采煤方法。翻译部分主要内容是关于压力和温度波动对近红外在煤矿井下测量瓦斯的影响的研究,英文题目

4、uang mine. Wangzhuang mine is located in Changzhi in Shanxi province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is 11.0 km,the width is about 4.5 kmand the total area is 49.3km2.The third are the main coal seam, and its dip angle is 25
5、 degree. The thickness of the mine is about 4.0m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 257.14 million tons,and the minable reserves are 186.40 million tons. The designed productive capacity is 1.8 million tons percent year, and the s
6、ervice life of the mine is 79.7 years. The normal flow of the mine is 144 m3 per hour and the max flow of the mine is 292 m3 per hour. The relative mine gas gush is 1.23 m3/t and the absolute gush is 4.22 m3/min, so it is a low gas mine.The mine is a single level in two shafts to develop. Te central
7、 laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway. The ventilation mode of this mine is center juxtapose form. The “three-eight” working system is used in the Wangzhuang mine. It produces for 330 days a year. This design includes t
