5、e underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.Zhang Shuanglou mine locates at the northwest of XuZhou, 79 km away from the center of the town. And it has convenience transportations. Minefield has a length
6、 of 5.2 km in the east and west direction while a width of 2.9 km in the south and north direction on average. The total area is Approximately 20.28 km2. The main coal seam in the mine is only one, which is the 7# coal seam. The average angle is 9 degree, while the thickness is about 5.0 m. The mine
7、field geological condition is simple.The proved reserves of the minefield are 147.68 million tons. The recoverable reserves are 108.54 million tons. The designed productive capacity is 1.2 million tons per year. The service life is 64.6 years. The normal flow of the mine is 320 m3 per hour and the m
8、ax flow of the mine is 340 m3 per hour. The Relative gas discharge quantity is 0.77 m3 per ton. Thus it is Low gaseous mine. The coal dust of the mine has explosion hazard. But the coal seam has no spontaneous combustion. The development of the mine is two level of vertical shaft,deepening with Incl
