摘要 本设计包括三个部分：一般部分、专题部分和翻译部分。 一般部分为矿t/a新井设计。煤矿位于省市交通便利井田走向（）长约，倾向（）长约，井田总面积为2。主采煤层为号煤、号煤，平均倾角为13，煤层平均总厚为m。井田地质条件较为简单 井田工业储量为12555万t，矿井可采储量9003万t。矿井服务年限为53.6 a，涌水量不大，矿井正常涌水量为60 m3/h，最大涌水量为120 m3/h。矿井绝对瓦斯涌出量为10 m3/min，相对瓦斯涌出量为3.024 m3/，为低瓦斯矿井。 井田为开拓。大巷采用胶带运输机运煤，辅助运输采用。矿井通风方式为式通风。 矿井年工作日为30 d，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-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10.矿井技术经济指标。 专题部分题目是 翻译部分Study on fault induced rock bursts，主要 关键词：矿井设计，立井开拓，冲击矿压，断层  ABSTRACT This design includes of three parts: the general part, special subject part and translated part. As the general part of the paper, a new design of Sanhejian mine has been completed. Sanhejian mine is situated in North of Xuzhou city of Jiangsu province. The traffic of road and railway is very convenience to the mine. The run of the minefield is 4.31 km ,the width is about 3.75 km，well farmland total area is 15.69 km2.The seven and nine are the main coal seam, and the dip angles are 13 degree. The thickness of the mine is about 6.0m in all and the geology of the coalfield is simple. The industrial reserves of the minefield are 125.55 million tons and the recoverable reserves are 90.03 million tons. The designed throughput of coal is 1.2 million tons per year, and the service life of the mine is 53.6 years. The normal flow of the mine is 60 m3 per hour and the max flow is 120 m3 per hour. The absolute outflow of gas is 10 m3/min and the relative gas emissions 3.042 m3/t as a low gas mine. Sanhejian mine is developed by vertical shaft with a single level. In main haulage way, the coal is transported by belt conveyer, and the mine car is auxiliary transportation in main rail-tunnel. The ventilation mode of the mine is center to center. “Four-six” as the working system is used in the Sanhejian mine. It produced 330d/a. The general part includes ten chapters: 1.An outline of the mine and the geology of the coalfield; 2.Boundary and the reserves of mine; 3.The service life and working
