FIELD: mining.
SUBSTANCE: invention relates to a method of disintegration of ores, rocks and other solid materials, in processes of preparation of mineral raw materials for dressing. For ore disintegration they simultaneously explode two or more parts of ore via an air gap. Each part of ore is processed with cumulative charges. Hollows of explosive charges are directed towards each other before explosion.
EFFECT: invention increases the efficiency of raw materials disintegration.
