阳泉三矿1.8Mta新井设计【专题神东矿区防溃水溃沙技术浅谈】.pdf

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 1.8 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。井田内主采煤层为一层，为 15#煤。煤层倾角平均 5，平均厚度 6.0 m。井田地质

2、条件较为简单。矿井工业储量为 17834.6 万 t，可采储量为 11818.6 万 t。矿井设计生产能力为 1.8Mt/a。矿井服务年限 51.9a。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东西两翼增加两个边界风井。矿井年工作日为 330 d，日净提升时间 16h，工作制度为“三八制”

3、。专题部分题目是神东矿区防溃水溃沙技术浅谈。本文论述了神东矿区发生溃水溃沙事故的实例，分析了煤矿发生溃水溃沙的地质、水文条件，讲述了在神东特定条件下发生溃水溃沙事故的原理和预防、治理溃水溃沙的措施。翻译部分是一篇关于地域因素影响下中国能源需求上限前景的论文，英文题目为Prospect of the upper limit of the energy demand in China from regional aspects。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 ABSTRACT This design includes three parts:the general p

4、art,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 coalfield;5.

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,7.5 km away from t

6、he 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 main coal seam in the min

7、e is only one,which is the 15#coal seam.The average angle is 5 degree,while the thickness is about 6.0 m.The minefield geological condition is simple.The proved reserves of the minefield are 178.3million tons.The recoverable reserves are 118.2 million tons.The designed productive capacity is 1.8 mil

8、lion tons per year.The service life is 51.9 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 Low gaseous mine.The coal dust of the mine has non-explosion hazard.But the coal seam is easi

9、ly 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 only one.Comprehensive mechanization puts in the top coal technology is the mining method.Sever

10、al 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 the late stage two air shafts in the boundary should be driven.The ventilation method is extraction

11、.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“The technology of preventing collapsing of water and blowning sand at shendong mining”.This article discussed the example of coll

12、apse of water and blown sand at shendong mining，analysis the hydrology and geology conditions of collapsing of water and blowning sand at coal，narrate the princples of collapsing of water and blowning sand and preventing and govennancing measures at the specific conditions of shendong.The translated

13、 academic paper is about the upper limit of the energy demand in China.Its title is“Prospect of the upper limit of the energy demand in China from regional aspects”.Keywords:main-inclined shaft and auxiliary-vertical shaft;strip district;comprehensive mechanization puts in the top coal;overhead line
