The influence of blasting on Kemess hypogene ore milling
Traditionally, optimization of drill and blast practices have taken place with sole respect to minimizing mine unit cost (as opposed to the operation as a whole), whilst maintaining fragmentation at a level that is considered ...
An Experimental Investigation of the Effect of Blasting on the Impact Breakage of Rocks
Size reduction represents one of the most energy-intensive and costly processes in the extraction of valuable minerals and rocks. Drilling and blasting, being the first operation in the size reduction chain, may have a ...
The Effect of Fragmentation Specification on Blasting Cost
Drilling and blasting are seen as sub-systems of size reducing operations in mining. To have better design parameters for economical excavation of mineral production and fragmentation, the comminution and fragmentation ...
