METHOD TO REDUCE DUST CARRYOVER FROM MAN-MADE MASSIF SURFACE Russian patent published in 2006 - IPC E21C41/32 

FIELD: environment protection, particularly to protect nature against dust blown off with wind from man-made massif surfaces.

SUBSTANCE: method involves contouring dust-forming surface and creating protective structures on dust-forming man-made massif surface in two mutually perpendicular directions, namely transversely to and along prevailing wind action directions; determining wind speed V_lim, m/s which provides maximum permissible dust concentration and maximal prevailing wind speed V_max, m/s at massif sanitary zone boundary; partitioning man-made massif surface into square areas; installing protective barriers along protective barrier perimeters, wherein the protective barriers are formed of cellular material. Each square area has side length L_ar determined from mathematical expression.

EFFECT: reduced dust carryover.
