mining industry, isolation of fire and fire- risky sections in coal mines. SUBSTANCE: blast-proof stopping has forms coming in the form of metal grid and agent filling space between forms. Metal grid comprises metal bars and is linked to environment in working with the use of anchors. Vertical and horizontal bars in adjacent rows of forms are displaced by half-distance between them. Bulk bags with loose material are employed as filling agent. EFFECT: considerably enhanced efficiency of fire protection of gas-hazardous mines, potential for safety of miners with simultaneous reduction of time and means for liquidation of accidents. 2 dwg |
