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。一般部分为阳泉三矿4.0 Mt/a新井设计。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.矿井工作制度及设计生产能力、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。阳泉三矿位于阳泉矿区的西部，距阳泉市中心7.5公里，交通便利。井田形状近似长方形，东西长约7.6 km，南北宽约3.0 km，面积约21 km2。井田内主采煤层为两层，为3#煤、15#煤。煤层倾角平均5；3#煤平均厚度7.0 m，15#煤平均厚度9.0

2、 m。井田地质条件较为简单。矿井工业储量为47093.57万t，可采储量为31491.21万t。矿井设计生产能力为4.0Mt/a。矿井服务年限60.6 a。矿井涌水量不大，正常涌水量为50 m3/h，最大涌水量为100 m3/h。矿井相对瓦斯涌出量为4 m3/t，属低瓦斯矿井。矿井煤尘无爆炸危险性，但煤层易自燃，自然发火等级为I级。矿井采用主斜井副立井单水平开拓。一矿一面，采煤方法为综合机械化放顶煤开采。全矿采用胶带运输机运煤，辅助运输采用矿车。矿井通风方式前期为中央并列式，后期根据需要在井田西翼增加一个边界风井。矿井年工作日为330 d，日净提升时间16h，工作制度为“三八制”。专题部分题目

3、是煤矿气体充填开采法技术可行性分析。本文提出了一种全新的煤矿充填方法，并对其在技术层面进行了可行性研究。翻译部分是一篇覆岩采动水平裂隙的定位：现场监测与预计的论文，英文题目为“Localization of mining-induced horizontal fractures along rock layer interfaces in overburden: field measurements and prediction”。关键词：主斜副立；带区；综放；架线电机车运输；中央并列式通风ABSTRACTThis design includes three parts: the genera

4、l part, special subject part and translation part.The general part is a new design of NO.3 of Yangquan mine. This design 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 coa

5、lfield; 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.No.3 of Yangquan mine locates at the west of Yangquan Mine area,

6、7.5 km away from the center of the town. And it has convenience transportations. The shape of minefield is like a rectangle which has a length of 7.6 km in the east and west direction while a width of 3.0 km in the south and north direction on average. The total area is Approximately 21 km2. The mai

7、n coal seam in the mine is two, which is the 3# coal seam and 15# coal seam. The average angle is 5 degree, while the thickness of the 3# coal seam is about 7.0 m and that one is about 90.m The minefield geological condition is simple.The proved reserves of the minefield are 470.9million tons. The r

8、ecoverable reserves are 315.9 million tons. The designed productive capacity is 4.0 million tons per year. The service life is 60.6 years. The normal flow of the mine is 50 m3 per hour and the max flow of the mine is 100 m3 per hour. The Relative gas discharge quantity is 4 m3 per ton. Thus it is Lo

9、w gaseous mine. The coal dust of the mine has non-explosion hazard. But the coal seam is easily spontaneous combustion. The level of spontaneous combustion is I.The development of the mine is single level with a main inclined shaft and an auxiliary vertical shaft. The number of the working faces is

10、only one. Comprehensive mechanization puts in the top coal technology is the mining method. Several belt conveyers undertake the job of coal transport in the mine, while the auxiliary transportation system depends on the mine cars. The ventilation type in the early stage is centralized juxtapose. In

11、 the late stage two air shafts in the boundary should be driven. The ventilation method is extraction.The working days in a year are 330. Everyday it takes 16 hours in lifting the coal. The working system in the mine is “three-eight”.The title of the special subject part is “Analysis on technical fe

12、asibility of gas flashing system in coal mining”. A new method of filling system in coal mining is proposed ,and the paper studys that this new filling system can be used in coal mining or not by using technical analysis.The title of the special subject part is “Localization of mining-induced horizo
