SUBSTANCE: method is proposed to control cutting height of stripping combine drums, in which they register parameters of drums cutting-in into a side rock, and drum cutting height is set with control signals produced from the measured values. At the same time in process of mining works the measured values, which are registered, include consumption (ISM) of current by cutting motors that drive the drums, and also speed (VM) of stripping combine motion with the drum actuator.

Besides, for various conditions of extraction, depending on hardness of coal to be produced and side rock deposited nearby, they set a characteristic value for specific energy (ESP) of cutting, which, when exceeded, results in cutting-in of drums into the side rock, and appropriate control signals are formed for correction of drum cutting height.
