The Swebrec169 Function Linking Fragmentation By Blasting

Abstract a new threeparameter fragment size distribution function has been found that links rock fragmentation by blasting and crushing the new swebrec function gives excellent fits to hundreds of sets of sieved fragmentation data with correlation coefficients of 0 997 or better r2 0 995 over a range of fragment sizes of 23 orders of magnitude.

Rock Fragmentation Control In Opencast Blasting

1 introduction rock fragmentation distribution influences a range of mining and milling processes including load and haul rates crushing and grinding performance and ore recovery in beneficiation processes michaud et al 1997in opencast mining where blasting is employed for excavation the overall cost effectiveness of the production operations is compatible with optimization.

Optimum Blasting Is It Minimum Cost Per Broken Rock Or

In most mining operations the ore undergoes several processes such as drilling blasting loading hauling crushing grinding and liberation to become the final salable product drilling and blasting is an important step in this process chain and its results such as fragmentation muckpile shape and looseness dilution damage and rock.
