Citizen's Guide to Coal Mine Blasting in Indiana

Cast blasting is a type of blast design that uses the explosive energy to move overburden material across the pit. This technique allows approximately 25% to 50% of the rock to be moved without the use of mine equipment. This is a major cost savings to the mine. Although cast blasting requires more pounds of explosive for each cubic yard of rock
