BULKING FACTOR OF ROCK FOR UNDERGROUND …
Bulking is the phenomenon of volume increase that occurs when solid rock is broken (Nelson, 1965). The volume of broken rock may increase relative to the original volume because the broken rock pieces typically do not fit together perfectly, which results in an increase in void space included with the rock solids. Depending on its initial state of
