METHOD FOR DEVELOPMENT OF FLOODED ALLUVIAL WITH DREDGES

摘要

FIELD: mining.;SUBSTANCE: invention relates to mining industry, in particular to development of flooded alluvial deposits and man-made deposits of mineral raw material under conditions of prolonged subzero temperature. Method involves construction of water-lifting dams, development of sections of alluvial deposit between dams, additionally, in section with maximum ground water flow rate, peats are opened, a water-lifting dam are constructed, and with onset of subzero air temperature, passage of dredge is carried out on prepared section.;EFFECT: extending mining season of dredge during development of flooded alluvial deposits of minerals in conditions of subzero temperature, which increases its annual capacity.;1 cl, 1 dwg
