Purpose. Implement an estimate of the driving methods efficiency of inclined shafts of cyclic-line production technology at Ingulets Iron Ore Enrichment Works with use of drilling and blasting operations when breaking the strongest rocks. Methodology. In order to achieve this purpose, the main factors influencing the implementation of the effective technology of driving the inclined shafts. Findings. The level of efficiency of the developed technology is substantiated. Originality. The rational scheme and parameters of drilling and blasting operations with a combined application of short- delayed and delayed explosion of borehole charges have been developed. Practical value. The rational parameters of blasting operations during the construction of inclined shafts have been integrated.
