The article studies the influence of the mineral body offsetting on the schedule of current volumes of overburden stripping. This issue has not been specially studied in previous publications by various authors. The issue of replacing areas by linear sections making up the pit walls has been justified in calculation of the current overburden volumes in cross-sectional plan. A corresponding dependence has been received in order to create a schedule for minimal current overburden volumes and a schedule for changes in current volumes depending on the rising depth. The proposed approach helps to establish general regularities which can be used in selecting parameters and directions of mining operations.
