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

Comparison of methods for formation of the economic model of the deposit in determining pit limits

The methods forming an economic model of the deposit have been comparatively analyzed on the case study of the Oleniy Ruchey deposit. The method of mining appreciation with deepening and the iterative method have been compared. The mathematic boundaries for the open mining have been determined using economical blocked models in the MineFrame software. The results received have approved the efficiency of the iterative method
