Blasting has an important impact on mining and milling well beyond the necessary ability to dig and load the ore efficiently. There is an increasing body of blasting research indicating significant impacts in crushing and grinding. These include increased production through higher output and fewer delays for bridging and jamming by oversize. In addition,

Characterisation of ore for blasting will be different from that for crushing and grinding operations. For example, the rock mass structure in addition to its strength is very important for blasting, whereas the micro fracture network, grain size and grain characteristics may be important in comminution processes such as crushing and grinding.
