Definitely, the ore fragments from the open cut will consume much less energy in their crushing and grinding than the ones from the normal production blasting. Therefore, considering the fact that open cut blasting is mostly successful in mines, it should be feasible to use a much higher specific charge such as 3.0 kg/m 3 in mining production

The procedure is performed by a urologist on an outpatient basis and anesthesia is used. In shock wave lithotripsy, the person lies on a table or, less commonly, in a tub of water above the lithotripter.

Break it Better – Mine Blast Fragmentation. Jack Eloranta of Eloranta & Associates stresses the importance of timing a blast properly. “It may take days or weeks to drill out a pattern and loading might take hours or days. But, the time span that really matters is the interval from the detonation of one hole to the time the adjacent hole fires.
