摘  要

本设计包括三个部分：一般部分、专题部分和翻译部分。
一般部分为王庄矿3.0 Mt/a新井设计，共包括10章,分别为：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。
王庄煤矿位于山西省长治市北面，交通便利。井田走向（南北）长约12.76 km，倾向（东西）长约4.10 km，井田总面积为46.767 km2。主采煤层为3号煤，平均倾角为3°，煤层平均总厚为6.65m。矿井涌水量为3.1 m3/min，属涌水量小型。矿井瓦斯相对涌出量为2.22 m3/t，为低瓦斯矿井。井田地质条件较为简单。
井田工业储量为319.9 Mt，矿井可采储量235.9 Mt。矿井设计生产能力为3.0 Mt/a，服务年限为60.5a。根据井田地质条件，将主采煤层划分为一个开采水平，水平标高为+690 m，同时提出四个技术上可行开拓方案，通过技术经济比较，最终确定最优方案为：两斜井一立井单水平开拓，按带区和盘区布置，以带区式准备为主，盘区式准备为辅。在井田的大部分范围内，都按带区式准备，只是在井田内两条断层和井田南部边界断层附近按盘区式准备。
设计首采区采用带区准备方式，工作面长度230m，采用放顶煤采煤法，全部跨落法处理采空区。矿井年工作日为330d，工作制度采用“四六”制作业，三班生产，一班检修，生产班每班2个循环，日进6个循环，循环进尺0.8 m，矿井日产量9036t。主运输采用带式输送机运煤，辅助运输采用无轨胶轮车运输。矿井前期采用中央并列式通风，后期采用两翼对角式通风。通风容易时期矿井总需风量为6300m3/min，矿井通风总阻力为1488Pa，风阻为0.135Ns2/m8，等积孔为3.22m2。矿井通风困难时期矿井总风量为7726m3/min，矿井通风总阻力为2489 Pa，风阻为0.15Ns2/m8，等积孔为3.05m2。矿井通风容易。
专题部分题目是《浅析巷道掘进的现状与发展》。
翻译部分题目为《巷道宽度对围岩稳定性的影响规律》 ，英文题目为：Influence laws of roadway width on stability of surrounding rock
关键词：斜-立井开拓；单水平；带-盘区准备；倾斜长壁综放；高产高效；
 
ABSTRACT
This design includes of three parts: the general part, special subject part and translated part.
 The general part is a new design of 3.0 Mt/a for Wangzhuang mine. it 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 panelen; 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.
Wangzhuang mine lines in north of Changzhi in ShanXi province. The traffic of road and railway is very convenience to the mine. The run of the minefield is 12.76 km ,the width is about 4.10 km，well farmland total area is 46.767 km2.The three is the main coal seam, and its dip angle is 3 degree. The thickness of the mine is about 6.65m in all. The folw of the mine is 3.1m3/min,The normal flow of the mine is lower. The mineral well gas gushes the deal lower, for low gas mineral well.The geological condition of the mine is relatively simple.
The proved reserves of the minefield are 319.9 million tons. The recoverable reserves are 235.9 million tons. The designed productive capacity is 3 million tons percent year, and the service life of the mine is 60.5 years.According to the geological conditions, the Lord will run into a building,level evevation for +690m.Put forward four technically feasible development plan. Through the technical and economic comparison,determine plan is single level in an inclined well to expand.......
The design apply Belt area pereparation against the first band,the lengh of working face is 230m,use top coal caving to exploit it coal,fall to dispose worked out section.In the Wangzhuang mine,It produced 330d/a.and use "four-six" working system.Three classes production,One class examine and repair.The depth-web is 0.8m with six working cycles perday,daily production is 9036t.The belt conveyor is applied to transport coal and trackless transport is used in the auxiliary conveying.The mine adopts slope development with one mining level and exhaust ventilation, centralized juxtapose eariler and radial later.Easily ventialte need input air 6300m3/min,all resistance of ventilation is 1488 pa,windage is 0.135N.s2/m8,equivalent conductance is 3.22 m2,hardly ventilate need input air 7726m3/min,all resistance of ventilation is 2489 pa,windage is 0.15 N.s2/m8,equivalent conductance is 3.05 m2..
The topic of special subject parts is Analyses the status and development of roadway excavation
Translation part of main contentses is Influence laws of roadway width on stability of surrounding rock
Keywords：slope;single-level; sub-level caving mining; high production and high efficiency; roadway driving along next goaf for fully-mechanized caving face.
