Abstract

The result of an explosion in fractured rock depends on its degree of fracturing, which can be characterized by the fractional composition of lump sizes in the massif. Fractured massifs are usually classified into very large-block, large-block, medium-block and small-block. In order to predict the sustainable results of the mining, it is necessary to know the category of fracturing of the massif.
