Analysis of physical properties of granular materials on their numerical models (2D case)

The paper describes a method for determining the density and specific surface of package rock particles represented by discs with size corresponding to fragments real dump massifs (2D case). packing corresponds schemes dumping used in open-pit mining - areal peripheral ones. influence boundaries, which is located, on physical characteristics this massif porosity revealed. It was revealed that way formation bulk affects its density, especially at boundaries massif. formed accordance area technology has denser composition less affected effect than dumping. applied medium differs from statistical methods (e.g., Monte Carlo) well-proven static media, such as dumps filtering mining.
