Definition of optimum degree of crushing granite massif by explosion on crushed stone quarries

Abstract

The peculiarity of solving the problem of optimality of rock crushing by explosion at crushed stone quarries is that simultaneously with the analysis of the quarry equipment, whose productivity depends on the output of large fractions of crushed material > 200 mm, it is necessary to consider the issue of reduction of small fractions of substandard material size < 3 mm.
