FIELD: mining industry, particularly ground improvement for underground structure building.
SUBSTANCE: method involves drilling bores, arranging freezing columns with liquid coolant in bores; communicating columns with reservoir filled with solid cryoagent; establishing circulation of liquid coolant and releasing gaseous cryoagent fraction. Reservoir is filled with solid cryoagent so that liquid coolant contacts directly with solid cryoagent to emit gaseous cryoagent fraction from liquid coolant.
EFFECT: reduced coolant temperature, decreased time of ground freezing out.
