ABSTRACT

A software tool for designing open pit large-scale blasts has been developed based on the mining and geological information system MINEFRAME. The given software allows predicting a location of the break line and shotpile surface taking into account the dynamic nature of the rock mass damage and interaction of borehole charges. For this purpose, imitation modelling was used, which allowed mathematical description of the rock mass damage, formation of break lines and shotpile surface of a fractured rock mass. The article describes an algorithm for large-scale blast modelling and shows the examples which confirm a good accordance between the simulation and a real blast.
