Case Study Cast Blasting

2012-8-22 · As the higher the drill angle the more the cast is, it is recommended to increase the drilling angle to 20 degrees. Larger diameter (229mm) is better suited for cast blasting for improved cast and cost. Cost analysis showed that designs with larger diameter blast holes lead to reduced mining cost and faster coal uncovery rate.
