6、des three parts: the general part, special subject part and translation part.The general part is a new design of NO.3 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.Dev

7、elopment 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.No.3 of Yangquan mine locates at the w

8、est 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 Ap

9、proximately 21 km2. There are mainly two coal seams in the mine 3# and 15#. First mining15# seam upstream mining.The average angle is 5 degree, while the thickness is about 7.5 m. The minefield geological condition is simple.The proved reserves of the minefield are 330.22million tons. The recoverabl

10、e reserves are 220.68 million tons. The designed productive capacity is 3.0 million tons per year. The service life is 61.3 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 gaseou

11、s mine. The coal dust of the mine has non-explosion hazard. And the coal seam is hardly spontaneous combustion. The level of spontaneous combustion is .The development of the mine is double level with two vertical shaft. The number of the working faces is only one. Comprehensive mechanization puts i

12、n 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 bounda
