Experimental study on mining method for thin ore body with extremely fractured and gently inclined roof thin rock mass
There are currently no reports on the use of new technologies or processes for the mining of extremely fractured and gently inclined thin ore bodies in thin roof rock masses.The mining still adopts mixed mining technology,and the high rate of waste rock mixing caused by mixed mining directly affects the economic and social benefits of the enterprise.The experimental research on the mining process of this type of ore body has important practical significance for reducing the waste rock mixing rate,improving the economic benefits of enterprises,and promoting the construction of green mines.
