Dynamics of dust suppression during blasting in permafrost mines
Authors:
Abstract
When driving preparatory coal workings in mines in the permafrost region, air dustiness after blasting reaches hundreds and thousands of milligrams per 1 m³ of air. The dust formed is the most harmful, because molecules of poisonous gaseous decomposition products of explosives are adsorbed on its surface, which have a toxic effect and accelerate the development of pneumoconiosis. ...
