FIELD: mining.
SUBSTANCE: device consists of heat-insulating structural elements located on water body surface. Heat-insulating elements are performed in a form of cylinders of the same length and diametre located close to each other with end face orientation in one plane parallel to creepers and dredgers longitudinal axis. Inside the cylinders along longitudinal axis there located is rigid axis with protruding ends that hinged to rods connected to axes of neighbouring cylinders. The rod ends are attached to creeper or dredger pontoon, the opposite ends are drilled into lane edge.
EFFECT: invention allows decreasing of labour intensiveness and extension of mining season in winter due to prevention of ice formation on water body surface, provision of creepers and dredgers free manoeuvring.
