impacts of opencast mining: removal of vegetation from the area designated for mining and other purposes produces dust which when air-borne causes an increase in the concentration of spm in the surrounding air. removal, handling, transportation and storage of soils also cause an increase in the concentration of spm in the atmosphere.
