FIELD: mining industry, applicable for localization of destruction area by attenuation of air shock waves and prevention of scattering of rocks destructed by explosion. SUBSTANCE: air shock waves are suppressed by shields of freely handling flexible members - ropes, bands and cords of synthesized fibres, and a perforated shield, localizing the scattering of solid products of destruction, is placed behind the last rows of flexible members that are most remote from the point of explosion. EFFECT: enhanced efficiency. 2 dwg
