Dust control at deep hole drilling for open pit mines

Large diameter (60 mm-250 mm) deep holes (5-10 m or more) are drilled in opencast mine for bench blasting. This produces huge quantities of fine dust. This dust gets dispersed in mine atmosphere and its neighbouring places by natural ventilation. The mine dust is a potential hazard in many ways. The existing dust control devices are inadequate and hence rarely seen in operation in mines.
