6、ation of the mine; 10.The basic economic and technical norms.No.3 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 7.6 km in the east and west
7、direction while a width of 3.0 km in the south and north direction on average. The total area is Approximately 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 geologi
8、cal condition is simple.The proved reserves of the minefield are 330.22million tons. The recoverable 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
9、mine is 100 m3 per hour. The Relative gas discharge quantity is 4 m3 per ton. Thus it is Low gaseous 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
