摘要
本设计包括三个部分:一般部分、专题部分和翻译部分。
一般部分为荆各庄矿120万t/a新井设计。荆各庄煤矿位于河北省唐山市东北部,交通便利。井田南北长约3.5 km,东西长约3.4 km,井田总面积为9.0 km2。主采煤层为9号煤、12号煤,平均倾角为14°,煤层平均总厚为16.12 m。井田地质条件较为简单。
井田工业储量为19172万t,矿井可采储量6418.27万t。矿井设计生产能力120万t/a,9号煤层服务年限为40 a。矿井正常涌水量为223.8 m3/h,最大涌水量为570 m3/h。矿井瓦斯涌出量较低,为低瓦斯矿井。
井田划分为两水平,第一水平标高为-375 m,第二水平标高为-570 m,双立井开拓一水平暗斜井延伸二水平,主井采用箕斗提升,副井装备罐笼。大巷采用胶带运输机运煤,辅助运输采用窄轨铁路配合矿车运输。矿井通风方式为中央边界式通风。
矿井年工作日为330 d,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。
专题部分题目是“大倾角工作面的开采与应用”。主要介绍了近年来由于荆各庄矿业公司煤炭剩余可采储量越来越少,布置综采工作面越来越困难,导致生产衔接特别紧张,为了缓解这种矛盾,进一步挖潜煤碳资源,该矿对大倾角煤层采用了综放工艺。通过技术人员大胆探索实践,在1426大倾角工作面第一次成功实施综采放顶煤工艺,提高了煤炭资源回收率,取得了良好的经济效益。
翻译部分主要内容为关于煤炭开采是污染煤炭开采处地下水得主要环境影响因素之一。在这篇中提出了一套强有力的地下水控制支持决策体系的方法叫做GCDSS其主要功能包括矿井特征描述的整合作用、数字的模型、危险评估和再调整技术的选择,为今后的实现绿色开采提供了一种新的技术支持。

ABSTRACT
This design consists of three parts: the general part, the special part and translated part.
The general part is a new design of JingGeZhuang mine, 1.2Mt/a. JingGe Zhuang mine lines in Northeast of TangShan in HeBei province. The traffic of road and railway isvery convenience to the mine. The N-S of the minefield is 3.5 km,the W-E is about 3.4km,the area is 9.0㎞2.The 9#coal seam and 12# coal seam is the main coal seam, and its dip angle is 14 degree. The thickness of the mine is about 16.12m in all. The geological structure of this area is simple.
The proved reserves of the minefield are 19172 million tons. The recoverable reserves are 6418.27 million tons. The designed productive capacity is 12 million tons percentyear, and the service life of the mine is 40years. The normal flow of the mine is 223.8 m3 percent hour and the max flow of the mine is 570 m3 percent hour, and the gas of the mine is low gaseous mine.
The minefield is divided into two levels, the first level of-375m elevation, elevation to the second level-570m. Shaft open up a two-level subinclined shaft extends two levels, the main shaft using skip upgrade equipment belonging cage. Roadway used to transport coal belt conveyor, auxiliary transport using narrow-gauge railway transportwith tub. Mineventilation central borderventilation.
Theworking system“three-eight” is used in the JingGeZhuang mine. It produced 330d/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 andworking 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. Theventilation and the safety operation of the mine; 10.The basic economic and technical norms.
The special subject parts of topics are" great inclination angleworking surface practice and exploration". In recentyears mainly because of Jinggezhuang coal mining company, the remaining recoverable reserves diminishing, Layout fully mechanized coal face increasingly difficult, especially convergence lead to the production of tension, in order to alleviate these contradictions, Future potential coal resources of the mine steeply dipping seam of Face layout.. Through technical personnel bold explorations., in 1426 Face of large tilt angle successful implementation of the first fully mechanized coal caving method, the recovery of the coal resource. achieved good economic results.
The translation part of main contentses pollute for the groundwaterwhich mines position concerning the control coal of judge the development problem of system. This paper presents a robust decision support system named GCDSS that integrates the functional components of mine characterization, numerical modeling, risk assessment and remediation-technique selection. The results from a case study indicated this system can help improve efficiencies of groundwater pollution control at coal-mining contaminated sites, mined to provide a kind of new technique support for the carry out of aftertime green.
