Abstract

The dynamic processes of stress waves propagation and cracks extension from adjacent boreholes in epoxy resin have been recorded with the dynamic photo-elastic apparatus (WZDD -1). New type synchronism control of large power multiple-row rounds detonate is solved. The general laws of break through of cracks have been analysed and studied preliminarily for adjacent boreholes detonated simultaneously or with a short delay time. New experimental techniques and useful information on practical basis have been offered for studying the mechanism of short delay blasting multiple-row rounds.
