The article examines the increase in the slope angle of the working side of the quarry depending on the width of the strip of additional reserves to be opened after the end of the sliding rear sight separation above the roof of the ore body and the annual rate of deepening along the contact of the ore body from the horizontal displacement velocity of the rear sight. The graphs are constructed for the case of use on board a single rear sight, the deposit is located in a zone of disagreement in the area of peak volumes of "overhanging" overburden. The charting shows that the nature of the change in the rate of advance of the mining front in both types of phased mining is the same (parabolic dependence), and the intensity of mining operations in cascade mining is higher. The two studied mining procedures are compared (against the background of the traditional non-staged one) according to the calendar distribution of ore volumes and overburden.
