FIELD: mining.
SUBSTANCE: method of frozen rock hydraulic melting consists in removing soil-vegetable layer off melted site. Parallel feeding and draining trenches are constructed at the site. Linear rows are bored between the trenches; and dispersed charges of explosive substances (ES) are placed in lower and upper parts of bores. Also depth of bores and correspondingly weight of ES charges are increased in the direction from feeding to draining trenches. Charges of ES are exploded with delay from the upper charge to the lower one and with delay in the direction from the feeding trench to the draining one, thus forming inclined filter channels in massif of frozen rock and facilitating rock melting by movement of heated by solar energy water to frozen rock via the feeding trench and filter channels.
EFFECT: upgraded efficiency of frozen mountain rock melting.
