Abstract

It is known that in technological processes of drilling, blasting, crushing and milling, depending on the conditions and nature of the application of the external load, different amounts of energy are spent on the destruction of a unit volume of rocks. The analysis shows that each of the widespread empirical laws of crushing is a part of a more general law of crushing, obtained by the authors of the article on the basis of the universal energy criterion of destruction taking into account the scale effect.
