FIELD: mining industry, in particular, mining of hard rocks in hindered conditions, when there is a necessity to preclude the spread of the blasted rock mass at re-activation of temporally idle non-mining flanks of dip open pits, blast near the complexes of the cyclic-flow production process, separation of the flasks of dip rock pits in highway engineering, etc. ^ SUBSTANCE: the shelter of the blasting areas by tyre mats includes the interconnected worn tyres laid on the surface to be basted bulk up in the form of a single-layer mar fastened with the aid of ropes or chains to the anchor installed in not deep holes on the surface of a bench. The automobile tyres of a single-layer mat laid on the horizontal surface to be blasted bulk up are filled with liquid, for example water. ^ EFFECT: enhanced ecological safety of blasting operations due to reduction of dust loading. ^ 2 cl, 3 dwg |
