Application of Mechanized Resuing and Filling Mining Method in Extremely Thin Veins in Deep Shafts
In view of the characteristics of the inclined to steeply inclined extremely thin ore veins in the Yanshan section of the Qijiagou mining area that the dip angle of the deep ore body is slowing down and the stability of the ore rock is deteriorating,the practical problems of large dilution and loss rates of the inclined to steeply inclined extremely thin ore veins and low production capacity of ore blocks are solved by combining the mining technology of resuing and filling with the mining technology of upward slicing and cemented filling by tailing.
