Title:
AUTOMATIC CUTTING METHOD WITH REDUCED SENSORS AND NO TEACHING FOR SHEARER IN INTELLIGENT FULLY-MECHANIZED MINING FACE
Document Type and Number:
WIPO Patent Application WO/2023/116103
Kind Code:
A1
Abstract:
An automatic cutting method with reduced sensors and no teaching for a shearer in an intelligent fully-mechanized mining face, comprising: initializing an automatic cutting parameter configuration data table according to three-dimensional modeling data of a coal mine coal seam of an intelligent fully-mechanized mining face; and in a process of performing automatic cutting according to the automatic cutting parameter configuration data table, automatically extracting, by means of a shearer in the fully-mechanized mining face, data such as the position, direction, speed, and cutting drum height of the shearer in a coal cutting process, and cleaning up redundant data in a process of cutting by one cut. The method implements automatic cutting technology of the shearer in the fully-mechanized mining face without teaching is achieved, and improves the intelligent running effect of drum shearers. Also provided is an automatic cutting system with reduced sensors and no teaching for a shearer in an intelligent fully-mechanized mining face.
