Abstract
The new variant of elaboration system of ore deposits with sublevel rockfall and local shrinkage of broken ore has been proposed. The results of simulation of ore mass drawing have been shown, the optimal parameters of the new technology, its conditions and functional area have been substantiated. The estimation of technical-economical efficiency, comparing with other known variants has been done.
