Since grinding feed is typically less than 3/4inch, it will only be the smallest macrofractures, and the microfractures that survive to reduce the resistance to grinding. The degree to which this happens is presently unclear. There is evidence that Bond work index is significantly reduced by heavier blasting (Nielsen and Kristiansen, 1996).
