METHOD TO VENTILATE SYSTEMS OF MINES

摘要

FIELD: mining.SUBSTANCE: method includes control of aerodynamic resistances of crosscuts or drives, which is carried out by installation of draught sources of oriented action that do not prevent movement of mine transport in crosscuts or drives, apart from the first one. While providing for even air distribution in crosscuts or drives, depressions of draught forces are determined from the expression given in the description text and claims. Action of draught sources is oriented depending on the sign of their rated depressions. Finishing of air flow rates in crosscuts or drives to the specified mode is arranged depending on the calculated depression.EFFECT: increased efficiency of ventilation of mine systems due to development of a logic for calculation of balancing of controller depressions.1 dwg
