When developing rocks using drilling and blasting operations (DBO), serious problems arise in terms of technological provision of safe conditions. This article outlines the experience of performing a significant amount, analysis of the theory and practice of blasting operations at the quarries of Almalyk and Navoi mining and metallurgical plants, which allowed to establish the insufficiency of theoretical and practical research on the development of safety system for blasting, management of the magnitude of the striking factor, contributing to damage reduction. Consistently disclosed the results of the study of the degree of technological risk at the plants for the production of emulsion explosive compositions, set out the authors developed classification of dangerous events in the operation of the plant of emulsion explosives with the presentation of a set of appropriate measures to prevent them. This work recommends a comprehensive safety system for the operation of an emulsion explosives (EME) plant, which allows for the safe production of EME at the plant while reducing the existing risk level of the plant from 6.5 points to 4.0 points. Safe conditions for blasting in deep quarries were recommended in terms of the introduction of radio control of explosions, the development of a predictive assessment of blasting operations near mining equipment and utilities in terms of the damaging effect of pieces of blasted rock, which made it possible to increase the safety and efficiency of blasting operations in deep quarries.
