Summary:Given the increased environmental concerns in excavation works, particularly in urban areas, the search for new and more accurate mathematical models for blast-induced ground vibration amplitudes prediction is mandatory, as these mathematical models are good tools for the minimization and mitigation of the environmental impacts related to these dynamic events. This paper presents the methodology-based proposal, selection and validation of multiple linear models in which the predictors are not only distance and explosive weight per delay but also RMR as a quantitative predictor and building type, as a qualitative predictor. The methodology was successfully applied to a case study of blast monitoring during excavation works of granite rock mass in Porto (Portugal). The obtained best-fitted model, with a coefficient of determination of 0.91 and sum squared error of 471.02, shows that these new predictors greatly improves the prediction ability of the blast-induced ground vibration amplitudes compared with conventional models. Moreover, the results show also that RMR has an important influence on blast-induced ground vibration amplitudes on ground vibration target structures.
