2、6946.84万t，可采储量为11570.445万t。矿井设计生产能力为1.8Mt/a。矿井服务年限50 a。矿井涌水量不大，正常涌水量为50 m3/h，最大涌水量为100 m3/h。矿井相对瓦斯涌出量为4 m3/t，属低瓦斯矿井。矿井煤尘无爆炸危险性，但煤层易自燃，自然发火等级为I级。矿井采用主斜井副立井单水平开拓。一矿一面，采煤方法为综合机械化放顶煤开采。全矿采用胶带运输机运煤，辅助运输采用矿车。矿井通风方式前期为中央并列式，后期根据需要在井田东西两翼增加两个边界风井。矿井年工作日为330 d，日净提升时间16h，工作制度为“三八制”。专题部分题目是冲击矿压的防治措施。冲击矿压是煤矿典型的

3、动力灾害之一。分析了影响冲击矿压的主要因素和发生条件并详细分析了各因素在冲击矿压中的作用机制, 为其预测和煤矿安全评价提供了理论依据, 在煤矿安全生产中具有重要的指导意义翻译部分是一篇关于无人工作面综合机械化刨煤机机组的研究和应用的论文，英文题目为Research and practice of unmanned mining face with full mechanized plow。关键词：主斜副立；带区；综放；架线电机车运输；中央并列式通风ABSTRACTThis design includes three parts: the general part, special subjec

4、t part and translation part.The general part is a new design of NO.3 productive capacity is 1.8million tons per year of Yangquan mine. 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.Deve

The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.No.3 of Yangquan mine locates at the we

6、st of Yangquan Mine area, 7.5 km away from the center of the town. And it has convenience transportations. The shape of minefield is like a rectangle which has a length of 7.6 km in the east and west direction while a width of 3.0 km in the south and north direction on average. The total area is App

7、roximately 21 km2. The main coal seam in the mine is only one, which is the 3# coal seam. The average angle is 5 degree, while the thickness is about 6.0 m. The minefield geological condition is simple.The proved reserves of the minefield are 169.5million tons. The recoverable reserves are 115.7 mil

8、lion tons. The designed productive capacity is 1.5 million tons per year. The service life is 50 years. The normal flow of the mine is 50 m3 per hour and the max flow of the mine is 100 m3 per hour. The Relative gas discharge quantity is 4 m3 per ton. Thus it is Low gaseous mine. The coal dust of th

9、e mine has non-explosion hazard. But the coal seam is easily spontaneous combustion. The level of spontaneous combustion is I.The development of the mine is single level with a main inclined shaft and an auxiliary vertical shaft. The number of the working faces is only one. Comprehensive mechanizati

10、on puts in the top coal technology is the mining method. Several belt conveyers undertake the job of coal transport in the mine, while the auxiliary transportation system depends on the mine cars. The ventilation type in the early stage is centralized juxtapose. In the late stage two air shafts in t

11、he boundary should be driven. The ventilation method is extraction.The working days in a year are 330. Everyday it takes 16 hours in lifting the coal. The working system in the mine is “three-eight”.The projects section topic is rock-burst prevention measures. Rock-burst is one of the typical dynami
