FIELD: mining industry.
SUBSTANCE: heat waves suppression device consists of mine channel with well sections made therein. Each well of section is provided with conic aperture at entry into rock, and at end of well - by chambers for destroyed rock, remote from each other and from longitudinal channel axis. Each section of channel wells is made with saw-like surface, projections of which are directed against possible direction of air strike wave. In recesses of sections conical apertures are positioned, from which wells are placed at sharp angle ±(10÷70°) to direction of air strike wave.
EFFECT: higher efficiency and durability.
