摘 要 本设计包括三个部分:一般部分、专题部分和翻译部分。 一般部分为赵家寨煤矿5.0Mt/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。 赵家寨煤矿位于河南省新郑市,区内交通十分便利。井田东西走向长约13.5 km,南北倾向宽3~4km,井田面积约47km2。井田可采煤层共有四层,主采煤层二1。二1煤层倾角在0o~14o,平均厚度8.0m。矿井工业储量为533.59Mt,可采储量为405.78Mt,矿井服务年限62.4a。矿井正常涌水量为600m3/h,最大涌水量为650m3/h。矿井相对瓦斯涌出量为4.436m3/t,绝对瓦斯涌出量为30.806m3/min,属低瓦斯矿井。矿井二1煤层为不易自燃煤层,煤尘具有爆炸性。 整个矿井划分为4个带区和2个采区。考虑到井田东西走向较长,前期采用中央并列式通风方式,后期根据需要在井田东西两翼各布置一个风井。矿井采用带区式准备方式,工作面设计长度240m,采煤方法为综合机械化放顶煤开采。矿井年工作日330d,昼夜净提升时间为16h。矿井采用“四六制”工作制度,三班生产,一班检修,生产班每班完成3个采煤循环。循环进尺0.8m,日产量为15151t。矿井煤炭采用胶带输送机运输,辅助运输采用蓄电池式电机车牵引固定箱式矿车。 专题部分题目是极易自燃煤层防灭火技术分析。本文针对极易自燃煤层自燃原因及其特点,阐述了我国煤层自燃对我国煤炭行业及国家经济的影响,以及目前矿井火灾预测预报,均压防灭火、阻化剂防灭火、惰性气体灭火、胶体防灭火等高技术含量的综合防治灭火技术在极易自燃煤层中的应用及其灭火技术的发展方向和易自燃煤层防灭火技术应用及成效 翻译部分是一篇关于建筑物下似膏体充填开采新工艺的探讨的论文,英文题目为A New Mode of Coal Mining Under Buildings with Paste-Like Backfill Technology。 关键词:立井 ;带区 ;综合机械化放顶煤 ;中央并列式通风 ; ABSTRACT This design includes three parts: the general part, special subject part and translation part. The general design is about a 5.0 Mt/a new underground 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.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. Zhaojiazhai Coal Mine lies in the west of Xinzheng City,Henan province.The traffic is convenient. It is about 13.5 km on the strike and 4~5 km on the dip,with the 47 km2 total horizontal area. There are 4 minable coal seam. The main aquifer coal is 2# coal seam with an average thickness 8.0m, and the dip of 2# coal seam is 0~14o. The proved reserves of coal mine are 533.59 Mt and the minable coal mine is 405.78 Mt. The service life is 62.4 years. The normal flow of the mine is 600m3 per hour and the max flow of the mine is 650 m3 per hour. The mine relative gas emission quantity is 4.436 m3 per ton,and the absolute gas emission quantity is 30.806 m3 /m3. Thus , it is Low gaseous mine. The coal seam has no spontaneous combustion tendency, but the coal dust has explosion hazard. The mine field is divided into 4 four strip districts and two mining district. Taking into account the long distance in the east and west direction. The type of mine ventilation is the centralized juxtapose ventilation at the beginning period. At the later period, the type of mine ventilation is the centralized juxtapose ventilation two wings diagonal ventilation. Designed first mining district makes use of the method of the mining district preparation. The length of working face is 240 m, which uses fully mechanized mining with top coal caving technology. The working days in one year are 330. Everyday it takes 16 hours in lifting the coal. The operation mode in the mine is four-eight with three teams mining and the other overhauling. Every mining team makes three working cycle. The advanced of a working cycle is 0.8 m, and quantity of 1.5151 Mt coal is maked everyday. Main roadway makes use of belt conveyor to transport coal resource, and mine car to be assistant transport. The monographic study entitled the fire-fighting analysis technology of extremely easy spontaneous combustion seam. Aiming at the spontaneous combustion easily causes and characteristics of spontaneous combustion seam, this paper expounds on the influence of spontaneous combustion seam to spontaneous combustion coal of the coal industry and national economy, and the influence of mine fire forecast, fire prevention, resistance pressure fire prevention, agents, inert gas fire-extinguishing, colloid fire extinguishing and high technology content of comprehensive prevention and control technology of fire in the application and the development direction of easily spontaneous combustion seam and the fire application and result of the fire prevention of spontaneous combustion coal technology Keywords: shaft ;strip district ;fully mechanized mining with top coal caving technology ;juxtapose ventilation ;
