As shitai railway and taijiu highway run across the southern part of the

6、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 with the average thickness 6.60 m , the average dip of 8. The geological resources/reserves of this coal mine are 393.26

7、 Mt, the proved resources/reserves are 389.83 Mt , the designed resources/reserves are 377.32 Mt and the minable resources/reserves are 273.11 Mt, with a mine life of 70.02 years.The geological condition of the mine is relatively simple. The normal mine inflow is 140 m3/h and the maximum mine inflow

8、 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 the d

9、ip 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 “four-six” working system is applied for coal mining . The monographic study is a thermal analysis of the
