has theorized that an alternative approach to drilling a cast blast pattern would be beneficial to coal mining operations by increasing drill utilization and therefore decreasing overall costs Increasing drill utilization results in an increase in the amount of time the drill is being productive more drill bit time in ground

overburden (a relatively soft sandstone) is removed during the mining at Centralia to expose the main coal seam which is 60 ft thick Cast blasting is not employed at the Centralia mine (cast blasting throws or casts the overburden off of the underlying layers) the overburden is simply broken up with explosives and removed using a drag line
