FIELD: mining industry, applicable in exploitation of flooded massifs. SUBSTANCE: the method consists in formation of pit cavities in the lower part of the holes and in charging of them with water-resistant explosive to a height not exceeding the level of flooding for displacement of water from the hole with a subsequent after- charging of holes with hydrolabile explosives in a time interval equal to 0.8 to 1 day. EFFECT: reduced expenditures connected with blasting.
