VERTICALLY DOWNWARDS PROPAGATING PILLAR WORKING

摘要

The invention relates to a cut-and fill method of a mine, where the working is done by pillar working, which propagates vertically downwards. The working is done by placing the stope and the pillars interlaced with each other when propagating downwards. The pillars are made by the hardening fillmethod and likewise, at the bottom of the excavated stope, in the lower corners, a bed of hardening fill is made.
