Abstract:

Limited progress in understanding blast mechanisms has led to significant discrepancies between the outcomes of existing blasting simulation techniques and actual blasting results, making it difficult to predict muckpile characteristics, optimize blasting designs, and guide on-site production. To address this challenge, this study presents a machine-learning-aided (ML-aided) method for blasted muckpile analysis, based on an innovative ML-aided post-blast ore boundary determination technique developed by the authors. This method enables accurate calculation of muckpile shape and ore distribution through six key steps: blast-induced rock movement database collection, machine-learning rock movement prediction model development, prediction model performance evaluation, blast block meshing, rock movement prediction, and rock element redistribution. Using this approach, the blasted muckpile and ore recovery can be predicted in advance. In this study, comparative analysis of simulated and field results from the dividing open-pit blast (DOPB) and center-initiation open-pit blast (CIOPB) methods demonstrated the engineering potential and effectiveness of this approach in reducing ore and profit losses through improved blasting techniques. This method can be regarded as a valuable addition to blast simulation techniques and highlights the potential for integrating artificial intelligence in mining engineering. © Society for Mining, Metallurgy & Exploration Inc. 2024.
