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. 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 the 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 one, 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 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 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 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 the 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 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 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 Applications in the Mining Industry”.Keywords: main-inclined shaft and auxiliary-vertical shaft; strip district; comprehensive mechanization puts in the top
