THE SIGNIFICANCE OF WAVE PROPAGATION AND PRESSURE PHASE IN EXPLOSIVE DETONATION PROCESSES

Main Article Content
Abstract
Rock fragmentation by means of drilling and blasting is considered one of the most optimal methods. In this process, the explosive energy—particularly the strength of its shock wave and the pressure exerted on the borehole walls—is among the key factors determining the degree of rock fragmentation. An analytical study and deeper interpretation of the explosive and blasting process help in optimizing the physical and mechanical properties of the explosive or in expanding and improving the efficiency of existing methods. In this context, the study and broader application of the waves generated during blasting and their significance are crucial factors. The blasting process is a physically and chemically complex phenomenon, in which the dynamic and thermodynamic forces that fragment rock initially manifest as waves and subsequently form pressure profiles; thus, studying them is essential to understanding the core essence of the blasting mechanism.
