Case Study Cast Blasting At Wilkie Creek Coal Mine

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. The overall result of the first cast shot was excellent and Peabody Wilkie Creek Mine is continuing to see benefits of this project.

Rock Fragmentation Control In Opencast Blasting

Apr 01, 2016 Presently, seams R-V and R-VI are being extracted by opencast method of mining. The mine is producing about 4.5 Mt of coal and removal of overburden is about 12 Mm 3. The stripping ratio of the mine is 1:4.72, i.e. 4.72 m 3 of overburden is to be removed for mining of 1 t of coal. The total coal reserve of the mine is 188.26 Mt.

Cast Blast Design Mininginfo

Cast blasting is a type of blast design which utilizes the surplus explosive energy to move overburden material across the pit. It is most frequently employed in coal mines to remove overburden from above the coal seam. This is achieved by arranging pits in long and narrow configurations that facilitate the movement of the blasted rock into the
