1、 摘 要本设计包括三个部分:一般部分、专题部分和翻译部分。一般部分为肖家洼煤矿4.0 Mt/a新井设计。肖家洼煤矿位于山西省兴县蔚汾镇肖家洼村,交通较为便利。井田倾向(东西)长约10.0 km,走向(南北)长约6.0 km,井田总面积为60.3 km2。主采煤层为13号煤层,平均倾角为12,煤层平均厚度为8.0 m。井田地质条件较为简单。井田工业储量为670.3 Mt,矿井可采储量482.5 Mt 。该矿井服务年限为89.4a,涌水量不大,矿井正常涌水量为16.7 m3/h,最大涌水量为77 m3/h。矿井瓦斯涌出量较低,为低瓦斯矿井。井田为立井两水平开拓;长壁放顶煤采煤法;矿井通风方式为分区
2、对角式。矿井年工作日为330d,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.采区巷道布置;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。专题部分的题目为放顶煤开采自然发火机理和防治方法。翻译部分的题目为地下工程地震危险性评估:理论与实践。ABSTRACTThis design includes of three parts: the general part, special subject part and translated part
3、. The general part is a new design of Xiaojiawa mine. Xiaojiawa mine lines in Xiaojiawa village in Weifeng town in Xing county in Henan province. The traffic of road and railway is convenience to the mine. The width of the minefield is 10.0 km ,the width is about 6.0 km,well farmland total area is 6
4、0.3km2.The 13 is the main coal seam, and its average dip angle is 12 degree. The thickness of the mine is about 8.0 m in all. The proved reserves of the minefield are 670.3 Mt. The recoverable reserves are 482.5 Mt. The designed productive capacity is 4.0 Mt percent year, and the service life of the
5、 mine is 89.4 years. The normal flow of the mine is 16.7 m3 percent hour and the max flow of the mine is 77 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well.The well farmland is two levels in vertical shaft development; the coal mine is the longwall mining; the p
6、artition ventilation.The working system “four-six” is used in the Xiaojiawa 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;
7、 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 Caving mining spontaneous combustion mech
