Abstract
Technological operations employed in preparing blocks for mining by the induced block-caving system are investigated. An estimate is given for the stress-strain state of the mass, and a rockburst-hazart criterion of deposit adopted as the ratio of the seismic energy accumulated in the rock mass to the potential energy contained in the explosion of charge is substantiated.
