Presplitting is a widely used controlled blasting technique in open-pit mining, aimed at minimizing damage to the remaining rock formation and ensuring greater stability (Pomasoncco-Najarro et al., 2022). By creating a pre-defined fracture line before the main blast, presplitting helps to prevent overbreak and unnecessary rock damage, which is especially crucial when dealing with less competent or weak rock masses.This article explores the fundamentals of presplitting, its significance in mining operations, and design considerations for effective application.Read the full document:
