Developing GPR model for forecasting the rock fragmentation in surface mines

Blasting operation is an economical and common method for rock fragmentation in civil construction works, surface and underground mines. The aim of this study is to present an accurate model for predicting the rock fragmentation (D80) induced by blasting in Shur river dam region, Iran, through Gaussian process regression (GPR). For this aim, 72 blasting events were investigated and the values of six parameters, i.e. burden, spacing, stemming,...
