2、储量为144.57Mt，可采储量为108.224Mt。矿井设计生产能力为1.5Mt/a。矿井服务年限51.53 a。矿井涌水量不大，正常涌水量为90m3/d，最大涌水量为135m3/d。矿井相对瓦斯涌出量为2.88m3/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。矿井采用斜井井单水平开拓。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”。专题部分题目是煤矿采空区充填选择及可行性研究。根据煤矿采空

3、区当前的现实情况为出发点，提出了采空区充填的现实依据。从点柱式膏体充填技术，覆岩离层注浆技术及采空区全部充填等不同角度对煤矿采空区的充填进行研究。翻译部分是一篇关于波兰硬煤开采技术研究的发展趋势的论文，英文题目为Directions of changes of hard coal output technologies in Poland关键词：斜井；采区；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 subject part and translation part.

4、The general part is a new design 1.5 Mt/a of dongping 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.Development engineering of coalfield; 5.The layout of mining area;

5、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.dongping of Yangquan mine locates at the west of Yangquan Mine area, 7.5 km away from the center of th

6、e town. And it has convenience transportations. The shape of minefield is like a rectangle which has a length of 3.6 km in the east and west direction while a width of 5.3 km in the south and north direction on average. The total area is Approximately 19 km2. The main coal seam in the mine is only o

7、ne, which is the 15# coal seam. The average angle is 7 degree, while the thickness is about7.5 m. The minefield geological condition is simple.The proved reserves of the minefield are 144.57Mt. The recoverable reserves are 108.224Mt.The designed productive capacity is 1.5 million tons per year. The

8、service life is 51.53 years. The normal flow of the mine is 90 m3 per hour and the max flow of the mine is 135 m3 per hour. The Relative gas discharge quantity is 2.88 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

9、 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 mechanization puts in the top coal technology is the mining method. Several belt co

10、nveyers 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 the boundary should be driven. The ventilation method is extraction.The w

11、orking 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 thematic part of the subject is a filling choice and feasibility study of the coal mining area. According to the current realities of the coal mining area as a starting

12、point, goaf filled realistic basis. Different angles from the column paste filling lying strata technology and the goaf all filling the filling of the coal mining area.The translated academic paper is about neural network applications in the mining industry. Its title is “Practical Neural Network Ap
