  • 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 Citizen's Guide to Coal Mine Blasting in Indiana

    The Surface Mining Control and Reclamation Act of 1977 (SMCRA) requires that coal mining be conducted in a manner that prevents injury to people and damage to public or private property during blasting. The side effects of blasting are “flyrock” a rock or rocks moving through the air or along the ground after a blast and travel beyond the blast area (security zone),
