Design well field recoverable resources 166Mt, the service life is 66a. This design mine pit selects the vertical shaft development method, divides two mining levels.Uses the grouping to concentrate the big lane arrangement, the big lane uses the 10t wire laying electric locomotive to tow the 3t bottom-dump mine car.The mining coal method is moves towards the long wall mining coal law, the mining coal craft for the synthesis mechanization mining coal craft. The year working day is 330 days, the use “four, six” the type working system, the work face length is 200m, each knife progress is 0.8m, shears nine knives every day, picks the depletion region processing method for to break down completely falls the law. The main well uses the multi-ropes to rub the ore basket promotion, the vice-well uses the rigid combination pot cage promotion. The mine pit well ventilated way for central passes in review to extract the type. key words saft area the level length of service long wall 2
