The article addresses a pressing issue faced by mining enterprises concerning the secondary breaking of oversize rock fractions. An increased oversize yield, along with the time and costs associated with its reduction, directly impacts the overall productivity and economic efficiency of the mineral extraction cycle. Based on the case study of LLC "YUUVP", the application of various secondary breaking methods is analyzed. The use of excavators equipped with mounted hydraulic breakers is substantiated as an optimal solution.
