Fines and Dust Generation and Control in Rock Fragmentation by Blasting
Blasting is carried out in most mines, producing very large quantities of fines/dust. In aggregate production, amount of fines produced ranges between 20%-40% (Mitchell et al, 2008, Poscoe et al., 2008). Mines have to face the problem of storage and use of fines. It is important to achieve the goal of reduced fines generation.
