Abstract

Based on the analysis of rock mass disturbance during blasting operations and their theoretical description, calculation schemes for determining geometric parameters depending on detonation conditions are proposed. The relations linking the parameters of drilling and blasting operations with the geometric dimensions of rock mass disturbance have been obtained, which makes it possible to predict this disturbance for various "know-how" of blasting operations.
