FIELD: mining.
SUBSTANCE: invention relates to monitoring the operation and control of cutting reels of a cleaning combine for a long bottomhole to obtain the required angle of moving forward. This angle of moving forward is called a “longitudinal roll” angle in this claim. A method includes stages in which the previous height of the longitudinal roll correction, the previous difference of the longitudinal roll and the previous obtained change in the longitudinal roll angle, which is the result of the change in the height of the cutting element of the sole based on the previous height of the longitudinal roll correction are stored in a storage device as statistical corrective actions for one or more previous passages of the cleaning combine, a sensor signal indicating the longitudinal roll angle of the cleaning combine is received, the profile of the planned longitudinal roll, setting the set of planned angles of the longitudinal roll for different sections of the ore bottomhole is accepted, by means of an electronic processor the difference of the longitudinal roll between the longitudinal roll angle and the planned angle of the longitudinal roll of the set of planned angles of the longitudinal roll of the profile of the planned longitudinal roll is determined, the value of compensation of the longitudinal roll is determined based on statistical corrective actions, by means of the electronic processor the height of the longitudinal roll correction is determined corresponding to the new height for the cutting element of the sole based on the difference of the longitudinal roll and the value of compensation of the longitudinal roll, and the height of the cutting element of the sole is changed by means of the electronic processor based on the height of the longitudinal roll correction.
EFFECT: invention provides monitoring and control of the longitudinal roll angle of the cleaning combine in the system of development with long bottomholes.
