Abstract
The method finds applications in thermo-abrasive destruction of mineral media and more particularly - in the destruction of mining mass and concrete. The method increases the effectiveness and improves labour conditions. By this method a high temperature gas flow is fed on the surface being destructed by means of a nozzle mouthpiece designed as a coaxially fitted, narrowing and widening part. Abrasive particles are introduced over the periphery of the gas stream, which are fed by the compressed air flow in the zone of the critical cross-section of the nozzle mouthpiece.
