Abstract

Prediction of maximum safe charge per delay (Q , kg) by Distance (D) from blasting point and adaptive Peak Particle Velocity (PPV) is a critical key for successful blasting. safe charge per delay is calculated by using PPV estimators indirectly or Q estimator directly. This paper presents the results of ground vibration measurement induced by bench blasting in Sungun copper mine. The scope of this study is to evaluate the capability of different methods in order to predict maximum safe charge per delay. Conventional empirical models and two type of new non-linear dirict estimator models are prsented. An application of Imperialist Competitive Algorithm (ICA) has used to determine the Q estimator coefficients in Sungun bench blasting. A comparison between two ways of investigations including conventional empirical equations and ICA are done. It has been shown that the applicability of ICA-based equations is more promising than any selected traditional empirical equations.
