Given in the paper are the results of experimental blasts in a limestone quarry for control of production of fines. The study indicated that fines can be kept to a minimum by reducing the charge factor to an optimum value, and by adopting a particular blasthole geometry. However, geological features imposed a limit on the reduction of fines.Chat Online
