摘 要
本设计包括三个部分:一般部分、专题部分和翻译部分。
一般部分为陈四楼1.5 Mt/a新井设计。陈四楼煤矿位于河南省永城市西北郊区,交通较为便利。井田倾向(东西)长约3.80 km,走向(南北)长约5km,井田总面积为18.13km2。主采煤层为2号煤层,平均倾角为9.73°,煤层平均厚度为7.43 m。
井田工业储量为190.31Mt,矿井设计可采储量115.77Mt 。该矿井服务年限为59.37a,矿井正常涌水量为894 m3/h,最大涌水量为1200 m3/h。矿井瓦斯涌出量较低,为低瓦斯矿井。
井田为立井单水平开拓;长壁放顶煤采煤法;矿井通风方式为中央并列式。
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-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。
专题部分的题目为:浅谈冲击矿压灾害机理及其防治技术。
翻译部分主要为煤与瓦斯延期突出的突变理论研究,英文题目为:A Catastrophe Model of Coal and Gas Delay Outburst。
关键词:陈四楼煤矿;立井单水平;无极绳绞车;变频对旋式通风机;冲击矿压;煤与瓦斯;延期突出
ABSTRACT
This design includes of three parts: the general part, special subject part and translated part.
The general part is a new design of Chensilou mine. Chensilou mine lines in north-west of Yongcheng in Henan province. The traffic of road and railway is convenience to the mine. The width of the minefield is 3.80 km ,the width is about 5.00 km,well farmland total area is 18.13 km2.The two is the main coal seam, and its average dip angle is 9.73 degree. The thickness of the mine is about 7.43 m in all.
The proved reserves of the minefield are 190.31 Mt. The recoverable reserves are 115.77 Mt. And the service life of the mine is 59.37 years. The normal flow of the mine is 894 m3 percent hour and the max flow of the mine is 1200 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well.
The well farmland is one level in vertical shaft development;the cole mine is the longwall mining;the central parallel ventilation.
The working system “three-eight” is used in the Chensilou mine. It produced 330 d/a.
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.The layout of panels; 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.
Special subject parts of topics is:Analysis of Outlooks,The mechanism and prevention of Rock-Burst.
Translation part of main contentses is A Catastrophe Model of Coal and Gas Delay Outburst.English topic is: A Catastrophe Model of Coal and Gas Delay Outburst。
Keywords: Chensilou coal; mineshaft single-level development; endless rope winch; rotating fan with frequence convision; rock-burst; coal and cas; delay outburst
