Аннотация

The paper addresses modern technological approaches aimed at improving blasthole utilization and preventing the formation of unbroken bottom zones (“cups”) during drilling and blasting operations in underground mine workings. The physical mechanisms responsible for cup formation, including non-uniform explosive energy distribution, lack of free surfaces, and specific features of detonation wave interaction with the rock mass, are analyzed. Scientifically substantiated methods such as reverse initiation of blasthole charges, intentional overdrilling, application of air gaps, combined stemming, and preliminary physico-chemical weakening of the rock mass using surfactants are considered. It is shown that the integrated application of these methods makes it possible to increase the blasthole utilization coefficient to 0.90–0.95, reduce the specific explosive consumption, and improve face quality while simultaneously decreasing seismic and environmental impacts.
