Control method of high-coal-dust thin coal seam shearer demonstration and representation of automatic cutting with wind direction

Abstract

The invention discloses a control method of high-coal-dust thin coal seam shearer demonstration and representation of automatic cutting with wind direction. The control method includes following steps: 1, demonstrating of automatic cutting of a drum shearer; 2, representing automatic cutting of the drum shearer: 201, initializing a drum shearer control system; 202, judging whether the drum shearer is positioned at the end or not; 203, representing automatic cutting of the left end of the drum shearer; 204, representing automatic cutting of the right end of the drum shearer. The high-coal-dust thin coal seam drum shearer cutting process with the wind direction is demonstrated and includes necessary processes during oblique-cutting feeding, triangular coal cutting, floating coal removing and coal cutting and mining during advancing of high-coal-dust thin coal seams with the wind direction, so that manual intervention is greatly reduced, automated coal mining requirements on coal mining process of the high-coal-dust thin coal seams with the wind direction are met, and full-automatic control efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of automatic cutting control of coal mining machines, and in particular relates to a teaching and reproduction automatic cutting control method of a high coal dust thin coal seam coal mining machine with wind direction. Background technique [0002] Promoting the energy revolution and orderly building a safe, green, and efficient energy system have become the "new normal" of my country's energy development. Apply the automation technology revolution to the coal mine energy industry to promote its development, especially the fully-mechanized mining face. The fully-mechanized mining face is the front line of work and the working environment is harsh; Improving safety performance and automation of fully mechanized mining equipment are the goals pursued by the coal industry; the current direct recognition technology of coal-rock interface is not yet mature, and memory cutting, as an indirect recognition technolo...

AI Technical Summary

Problems solved by technology

However, the previous automatic cutting control methods for coal shearers can only perform automatic memory cutting on the straight section of the working face, and cannot cope with complex and changeable coal cutting processes. Frequent manual intervention is required at the nose and tail of the shearer, and Poor use effect, single function
