Hydraulic backhoes are widely used in Kuzbass (Western Siberia, Russia) because the level of coal loss during their operation is much lower compared with traditional quarry excavators shovels. However, one of the mining enterprises’ designing problems is insufficient consideration of technological possibilities of this type of equipment, which leads to additional losses of coal and economic effect reduce. This article presents an approach to adaptation of the slope height considering the capabilities of backhoes in seam extracting which can sufficiently decrease coal losses and intensify open pit mining. This approach is based on a system of mining and geometrical calculations, allowing carrying out an accurate selection of equipment and technology to adapt the use of hydraulic backhoes to mini-
