چکیده
Blasting operations are the most conventional and frequently used rock breakage approach in field of Civil Mining Engineering. However, side effects induced by blasting may cause severe damages to surrounding areas. Air-overpressure (AOp) is one operations, which defined as air pressure wave generated operation that exceeds normal atmospheric pressure. It can result potential structural damage glass breaking therefore needs be well predicted subsequently minimized. In this study, 76 sets data were collected develop a predictive model estimate AOp value. due small size dataset, it hard determine complexity model. Therefore, for purpose developing machine learning with appropriate complexity, radial basis function network an additional second hidden layer (RBF-2) proposed, trained incremental design principle modified Levenberg–Marquardt algorithm. The performance proposed RBF-2 compared those five other techniques, i.e., multilayer perceptron (MLP), RBF, MLP optimized genetic algorithm (GA-MLP), multi adaptive regression spline (MARS) random forest (RF). results demonstrate outperforms models RMSE 2.02/1.98, MAPE 1.32%/1.40%, R 0.9828/0.9735 training/testing stage. Findings revealed emerged efficient, powerful robust technique predicting blast models.
