Casting overburden with explosives
In casting with explosives large amounts of low cost blasting agent are loaded into medium diameter blast holes in ratio of more than 1 lb of agent per cu yd of rock; resulting blast moves large portion of overburden into spoil area; this allows dragline to work on top of spoil pile; advantages are easier digging, less reclamation leveling, and more coal uncovered in less time.
