2020-6-2 · 2020-6-2 · Blasting operations create significant problems to residential and other structures located in the close proximity of the mines. Blast vibration is one of the most crucial nuisances of blasting, which should be accurately estimated to minimize its effect. In this paper, an attempt has been made to apply various models to predict ground vibrations due to mine blasting

2014-9-4 · To overcome these problems, the use of optimization algorithms such as ICA to train ANNs is of advantage. ICA has some advantages such as simplicity, accuracy, and time saving (Karami et al. 2012). In the current study, a new hybrid ICA-ANN has been developed to predict PPV induced by blasting in granite quarry
