FIELD: explosion equipment, in particular, destruction of the ice cover on rivers and basis.
SUBSTANCE: the method consists in delivery of explosive gas mixture under the ice cover with a subsequent initiation of the explosion of the latter. The explosive gas mixture is supplied to an elastic gas-tight shell preliminarily placed under the ice cover with a subsequent ignition of the gas mixture by electric explosion the explosive gas mixture is fed to the elastic gas-tight case alternately dosing the air and the fuel gas.
EFFECT: enhanced productivity in destruction of the ice cover, result and safety of blasting operations, technological effectiveness, reduced cost of operations, provided performance of blasting operations at a smaller distance from bridges and others structures.
