COAL MINING MACHINE ATTITUDE CONTROL METHOD BASED ON COAL SEAM GEOGRAPHIC INFORMATION SYSTEM

Abstract(summary):

Disclosed is a coal mining machine attitude control method based on a coal seam geographic information system. The method comprises: establishing an association model between a cutter undercut adjustment amount of a lower drum (4) of a coal mining machine and a roll angle variation amount in attitude information of the coal mining machine (3); establishing a coal seam geographic information system for a working face to obtain a curve of a coal seam roof (1) and a curve of a coal seam floor (2) in an advancing direction of the coal mining machine; and locating slope-change points on the coal seam floor curve to achieve segmental linearization of the coal seam floor curve. By employing a coal mining machine positioning technique integrated with geological environment information to obtain real-time position and attitude information of a coal mining machine, and utilizing an association model between a cutter undercut adjustment amount of a lower drum of a coal mining machine and a roll angle variation amount in attitude information of the coal mining machine, the present invention obtains, by means of computation, an undercut adjustment amount of the lower drum of the coal mining machine to control the attitude of the coal mining machine. The method of the present invention effectively combines attitude control of a coal mining machine and dip angle identification of a coal seam, such that a roll angle of an attitude of the coal mining machine remains consistent with the dip angle of the coal seam.
