FIELD: mining.
SUBSTANCE: method of atmospheric open-cast fumes prevention involves creating barriers in the way of movement of the dust cloud, its localization by placing a shelter in the open-cast working areas. A grid with a mesh size of 50 to 100 mcm and a height H calculated according to the above mathematical expression is set on the windward open-cast side, perpendicular to the movement of the air flow.
EFFECT: reduction of dust load on the atmosphere of the open-cast and its location area.
