Mining enterprises producing construction materials (e.g., crushed stone), as a rule, have a small capacity (up to 1.5-2 million m3 per year) and include a crushing and sorting shop.
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.
