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.GuoJiaHe mine locates at the north of LinYou city, 100 km away from BaoJi. And it has convenience transportations. The shape of minefield is like 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 thickness 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 mine 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 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 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. Everyday it takes 16 hours in lifting the coal. The working system in the mine is “three-eight”.The title of the special subject part is “Underground coal mine water on prevention and control principle and technology”. Coal mine underground water from the present situation, through the analysis of the flood of underground, finally, relates the exploitation of waterThe translated academic paper is about In the mining area within the scope of the soil structure of the interaction of the numerical research. Its title is “Numerical study of the soil–structure interaction within mining subsidence areas”.Keywords: main-inclined shaft and auxiliary-vertical shaft; strip district; fully-mechanized top coal
