Cast Blast Design

Cast blasting is a type of blast design which utilizes the surplus explosive energy to move overburden material across the pit. It is most frequently employed in coal mines to remove overburden from above the coal seam. This is achieved by arranging pits in long and narrow configurations that facilitate the movement of the blasted rock into the previously mined pit. This technique allows ...
