FIELD: blasting; can find application in various branches of industry using blasting processes, for example, for crushing of rocks, permafrosts, concrete. SUBSTANCE: blast-hole (deep-hole) extended charge is distinguished by the fact that it is formed in situ by mixing two explosive components separately, and the means for blasting is made in the form of blasting wire. The charge may have one or several cavities. The procedure of drilling and blasting operations is characterized by the fact that the means for blasting, made as blasting wire, is placed in an empty shell and only then the shell is filled with liquid explosive. EFFECT: enhanced efficiency. 5 cl, 3 dwg
