With the demand of national economy on mineral resources, commodity prices, while rebound, according to the profit and loss balance calculation, used to think that no mining efficiency of low grade ore, mining value. Now in terms of cost, to fill stoping application provides a more relaxed space, objectively requires us to use new technology, develop new ideas, focus on loose and broken in mining technology complex difficult mining safety mining of stone problem, as much as possible of the recovery of low grade ore. This article in view of the main shaft orebody midway through 650-700, in loose and broken slowly inclined layered ore body mining methods, innovation and suggest is put forward, and mining colleagues to discuss and try to solve the problem of loose and broken ore body mining safety, reduce the mining cost, reduce the loss and dilution create certain economic benefits.Because of the ore body of rock properties is bad, to adopt the new method. Between column extraction is conducted in the absence of artificial protection, can post safety mining can decide between the exposed area, therefore, must strictly control the spacing of mining height, strong mining strong, rapid filling.
