6、e mining field, the traffic is very convenient. Its about 4.4km on the strike and 5.5 km on the dip,with the 25.45 km2 total horizontal area. The minable coal seams of this mine is 15下 with the average thickness of 2.5 , the average dip of 8. The geological resources/reserves of this coal mine are11

7、4.26 Mt, the proved resources/reserves are 113.12Mt Mt , the designed resources/reserves are 110.31 Mt and the minable resources/reserves are 86.98 Mt, with a mine life of 55.77 years.The geological condition of the mine is relatively simple. The normal mine inflow is 140 m3/h and the maximum mine i

8、nflow is 220 m3/h. It is lean coal with low mine gas emission rate and coal spontaneous combustion tendency, and its a coal that has no dust explosion.This mine adopts vertical shaft development with one mining level and centralized ventilation. The adopted coal winning method is longwall mining to
