DETERMINING THE PERFORMANCE OF EXPLOSIVES FOR BLASTING MANAGEMENT

Experimental methods for determining a performance index of explosives are analysed: the ballistic pendulum, mortar, lead block, and according to volume soil explosion funnel. It is defined that determination emulsion (EE) involves set significant features connected with large critical diameter requiring experiments large-mass charges resulting in refusal from traditional index. Analytical calculating an relative analysed. Determination indices help analytical helps identify considerable differences calculation results; case results erroneously low at all. since do not consider brisant action explosives. This paper represents developed methodology degree detonation velocity. The proposed considers key energy characteristics explosives: heat products, density (thickness), use all explosive types makes it possible get correct necessary designing parameters drilling blasting operations.
