- W4206563882 abstract "Blasting is an indispensable part of the open pit mining operations. It plays a vital role inpreparing the rock mass for subsequent operations, such as loading/unloading, transporting, crushing, anddumping. However, adverse effects, especially blast-induced ground vibrations, are considered one of themost dangerous problems. In this study, artificial intelligence was supposed to predict the intensity ofblast-induced ground vibration, which is represented by the peak particle velocity (PPV). Accordingly, anartificial neural network was designed to predict PPV at the Coc Sau open pit coal mine with 137 blastingevents were collected. Aiming to optimize the ANN model, the modified version of the particle swarmoptimization (MPSO) algorithm was applied to optimize the ANN model for predicting PPV, called theMPSO-ANN model. For the comparison purposes, two forms of empirical equations, namely UnitedStates Bureau of Mining (USBM) and U Langefors - Kihlstrom, were also developed to predict PPV andcompared with the proposed MPSO-ANN model. The results showed that the proposed MPSO-ANNmodel provided a better performance with a mean absolute error (MAE) of 1.217, root-mean-squared error(RMSE) of 1.456, and coefficient of determination (R2) of 0.956. Meanwhile, the empirical models onlyprovided poorer performances with an MAE of 1.830 and 2.012, RMSE of 2.268 and 2.464, and R2 of0.874 and 0.852 for the USBM and U Langefors – Kihlstrom empirical models, respectively." @default.
