2、9570万t，可采储量为7031.3万t。矿井设计生产能力为5Mt/a。矿井服务年限93.75 a。矿井涌水量大，正常涌水量为1021 m3/h，最大涌水量为1054m3/h。矿井相对瓦斯涌出量为1.91 m3/t，属低瓦斯矿井。矿井煤尘爆炸危险性，煤层易自燃，自然发火等级为I级。矿井采用斜井单水平开拓。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，辅助运输采用无轨胶轮车。矿井通风方式前期为中央并列式，后期根据需要在井田西翼增加一个边界风井。矿井年工作日为330 d，日净提升时间16h，工作制度为“三八制”。专题部分题目是浅谈煤矿井下防治水原理与技术。从煤矿井下水的现状出发

3、，通过对井下水灾的分析，最后对保水开采进行了叙述。翻译部分是一篇关于在采矿塌陷区范围内的土壤结构相互作用的数值研究的论文，英文题目为Numerical study of the soilstructure interaction within mining subsidence areas。关键词：斜井单水平；带区；综放开采；无轨胶轮车；中央并列式通风ABSTRACTThis design includes three parts: the general part, special subject part and translation part.The general part is a

4、 new design of GuoJiaHe 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.Development engineering of coalfield; 5.The layout of mining area; 6.The method used in coal mining; 7. Trans

The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.GuoJiaHe mine locates at the north of LinYou city, 100 km away from BaoJi. And it has convenience transportations. The shape of minefield is lik

6、e a rectangle which has a length of 12.8 km in the east and west direction while a width of 8.0 km in the south and north direction on average. The total area is Approximately 80 km2. The main coal seam in the mine is only one, which is the No.3 coal seam. The average angle is 5 degree, while the th

7、ickness is about 10.0 m. The minefield geological condition is simple.The proved reserves of the minefield are 1019570million tons. The recoverable reserves are 703.3 million tons. The designed productive capacity is 5 million tons per year. The service life is 93.75 years. The normal flow of the mi

8、ne is 1021 m3 per hour and the max flow of the mine is 1054 m3 per hour. The Relative gas discharge quantity is 1.91 m3 per ton. Thus it is Low gaseous mine. The coal dust of the mine has non-explosion hazard. But the coal seam is easily spontaneous combustion. The level of spontaneous combustion is

9、 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 mechanization puts in the top coal technology is the mining method. Several belt conveyers undertake the job of coal transport in the

10、mine, while the auxiliary transportation system depends on the Trackless rubber_tyred car. The ventilation type in the early stage is centralized juxtapose. In the late stage one air shafts in the west should be driven. The ventilation method is extraction.The working days in a year are 330 days. Ev
