6、ss the southern part of the mining field, the traffic is very convenient. Its about 5 km on the strike and 5.5 km on the dip,with the 27.5 km2 total horizontal area. The minable coal seams of this mine are 9 and 15下 with the average thickness of 3.78 m and 1.8 m , the average dip of 8. The geologica

7、l resources/reserves of this coal mine are 220.11 Mt, the proved resources/reserves are 217.91 Mt , the minable resources/reserves are 156.68 Mt, with a mine life of 67.0 years.The geological condition of the mine is relatively simple. The normal mine inflow is 140 m3/h and the maximum mine inflow i

8、s 220 m3/h. Its relative mine gas emission is 6.69 m3/t and absolute mine gas emission is 24.67m3/min, so it is a low gas mine with no coal spontaneous combustion tendency, also its a coal that has no dust explosion.This mine adopts vertical shaft development with one mining level and centralized ve

9、ntilation. The adopted coal winning method is longwall mining to the dip or to the rise. The belt conveyor is applied to transport coal and track transport, is used in the auxiliary conveying. The workers work 330 days per year ,and exaltate 16 hours one day .The “three-eight” working system is appl
