Essay

In the thesis an actual scientific and technical problem of substantiation of rock blasting parameters involving stress conditions in the working face is solved. Organized and conducted comprehensive mine, laboratory and field-analytical studies of the efficacy of new compounds using hardening mixtures, used as tamping in tunnel blasting. The new way of rock destruction in stress conditions is worked out, using breaking-in charges with hardening mixtures that provides evengranular blasting fragmentation, increasing blasthole efficiency ratio and meets all regulatory requirements technological and environmental safety. Regularities resulting from research used to develop recommendations on provid-ing the efficiency of rock blasting for excavating permanent mine opening in mining and geological conditions of PJSC "Krasnodonvugillya."
