Abstract
In order to improve conveying and crusher throughput performance, major open pit mines are increasingly using high energy blasting. Strict and effective controlled blasting methods are required to protect the integrity of the pit walls from the increasing energy concentration. The M’haoudatt mine lacks pre-split procedures, which has led to unstable slopes and landslides that have increased the strip ratio. In order to correct mining anomalies, this work intends to evaluate pre-split practice. The aim of the work is to evaluate the pre-split performance in the M’haoudatt mine through tests carried out on one of the pit benches.
