Prediction of fly-rock during boulder blasting on infrastructure slopes using CART technique

open access: yesGeomatics, Natural Hazards & Risk, 2021
Boulder blasting is a different process from conventional bench blasting. Fly-rock produced in boulder blasting is a major safety concern due to the presence of 360° free-face which may result into excessive throw of the fragments radially up to 900 m ...
