摘 要
本设计包括三个部分：一般部分、专题部分和翻译部分。
一般部分为雁崖矿180万t/a新井设计。雁崖煤矿位于山西省大同市西南，交通便利。井田走向（东西）长约6.6km，倾向（南北）长约3.6km，井田总面积为23.76km2。主采煤层为11号煤、14-2、14-3煤，平均倾角为
3°，煤层平均总厚为9.3.m。井田地质条件较为简单。
井田工业储量为23233.08万t，矿井可采储量17162.40万t。矿井服务年限为57a，涌水量不大，矿井正常涌水量为200m3/h，最大涌水量为275m3/h。矿井瓦斯涌出量较低，为低瓦斯矿井。
井田划分为单水平，水平标高为+1230m，双斜井开拓，主斜井装备胶带运输机，副井装备提升机。大巷采用胶带运输机运煤，辅助运输采用轨道运输。矿井通风方式为中央并列式通风。
矿井年工作日为300d，工作制度为“四六”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-盘区巷道布置；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。
专题部分题目是雁崖矿煤层自燃发火机理及防治技术措施。主要对目前雁崖矿煤层自燃发火机理及防治技术的理论研究、应用现状、主要技术及存在问题进行了归纳，对煤层自燃发火机理及防治技术的应用进行了展望。
翻译部分主要内容是采用数值模拟的方法对非均质岩石的破坏进行预测做了介绍。
ABSTRACT
This design consists of three parts: the general part, the special part and translated part.
The general part is a new design of Yanya mine.Yanya mine lines in Northwest of DaTong in ShangXi province. The traffic of road and railway is very convenience to the mine. The geological structure of this area is simple. The run of the minefield is 6.6 km ,the width is about 3.6km，the area is 23.76㎞2.The 11 、14-2and 14-3 is the main coal seam, and its dip angle is 3 degree. The thickness of the mine is about 9.3m in all. The proved reserves of the minefield are 232.3308 million tons. The recoverable reserves are 171.6240 million tons. The designed productive capacity is 24 million tons percent year, and the service life of the mine is 57 years. The normal flow of the mine is 200 m3 percent hour and the max flow of the mine is 275 m3 percent hour, and the gas of the mine is low gaseous mine.
The field has been divided one mining level. The level should be located at the lever of +1230m, which use raise and dip mining method of slope development . The main slope install belt and the auxiliary slope install trolley rail haulage. The main entry transportation of the coal is using with the belts, and the auxiliary entry is using of trolley rail haulage The two wings opposite angles ventilation system is used in the mine.
The working system “four-six” is used in the Yanya mine. It produced 300d/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.
The topic of the special part is situation of Stress shifting technology used both at home and abroad. The article states the research in terms of theory, applying theory to practice at present, major technique and problem. In the end forecasts the future of this technical.
The matic sections entitled Yanya mine complex roof of coal roadway support technology. It mainly discribes the oretical research and application status, and the main technical problems of coal roadway supporting under the composite roof and discusses the application of supporting technology in the paper .
The translation part main introduces digital image-based numerical modeling method for prediction of inhomogeneous rock failure.
