P-wave attenuation in blasting

Abstract

This article addresses the critical yet often overlooked aspect of unloading behavior in rocks during blasting operations. It emphasizes the significant impact of P-wave attenuation on the burden of explosive charges, a factor crucial for the efficiency of blasting procedures. The research introduces an approach using the Schmidt Hammer Rebound Number (SHRN) as a tool for determining the burden. This method offers a fast, reliable, and cost-effective alternative to traditional techniques. Its adaptability for site-specific assessments makes it a valuable addition to the field.
