6、da geological conditions is relatively simple.The proved reserves of the minefield are 984.65million tons. The recoverable reserves are 691.08 million tons. The designed productive capacity is 7.0 million tons per year. The service life is 70.05 years. Mine average inflow of 516m/ h . Coal seam gas

7、emission in the case of low gas coal . The coal seams are dust explosion hazards and natural tendency to get angry .The development of the mine is double levels with vertical shaft at the first level and inclind shaft at the second level. The number of the working faces is only one. The mining metho
