The implementation of the algorithm of break surface simulation while designing the well breaking

A method of calculating the break surface formed as a result of blast-hole rings'' short-delay blasting has been developed. The method is based on simulation modeling of a process of broken rock separation from rock mass. A modeling tool has been implemented as a part of the module for designing cave large-scale blasts included in MINEFRAME software package. It has been shown that the tool can evaluate possible outcomes of the project of cave large-scale blast properly.
