obtaining names and phone numbers of the mine operators. Cast blasting Cast blasting is a type of blast design, that utilizes the explosive energy to move overburden material (rock that covers the coal seam) across the mining pit. Alt-hough cast blasting requires more pounds of explosive for each cubic yard of rock
typically used in surface coal mining to fracture the rock). After blasting, a dragline, shovels, trucks, or other heavy equipment remove the rocky overburden to expose the coal seam. CITIZENS GUIDE TO COAL MINE BLASTING IN INDIANA Indiana Department of Natural Resources Division of .

The mining activities that traditionally take place to advance a working face further into the coal seam, called unit operations, include cutting, drilling, blasting, loading, and hauling the coal from the current position of the face to the planned advance distance position of the face.
Increases in production and scale of equipment in the past thirty-five years have created a paradigm shift for drill and blast personnel at these large surface mines, and the explosives industry has yet to create a blast design method specifically tailored for large surface coal mine bench blasting.
