Automatic cutting control method for teaching playback of drum shearer for low coal dust thin coal seam

Abstract

The invention discloses an automatic cutting control method for teaching playback of a drum shearer for a low coal dust thin coal seam. The automatic cutting control method comprises the following steps: firstly, teaching automatic cutting of the drum shearer; secondly, playing back the automatic cutting of the drum shearer: 201, initializing a control system of the drum shearer; 202, judging whether the drum shearer is positioned at an end or not; 203, playing back the automatic cutting of the left end of the drum shearer; 204, playing back the automatic cutting of the right end of the drum shearer. According to the automatic cutting control method disclosed by the invention, the cutting process of the drum shearer for the low coal dust thin coal seam is taught, the necessary processes of performing beveling feed, triangular coal cutting, cleaning of float coal, coal cutting and coal mining in advancing on the low coal dust thin coal seam are covered, manual intervention is greatly reduced, the automatic coal mining requirement of the low coal dust thin coal seam on a coal mining technology is met, and the full-automatic control efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of automatic cutting control of coal shearers, and in particular relates to a teaching and reproduction automatic cutting control method of a low coal dust thin coal seam roller shearer. 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 technology of coal and rock, has develope...

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

In particular, the coal loading effect of the thin coal seam shearer drum is generally not good, and it is generally necessary to increase the process of cleaning the floating coal at the head and tail of the machine; in addition, when the concentration of coal dust in the mine is high, the line of sight of the coal mining face is not good, and the shearer is easy to be mistaken. The support frame of the fully mechanized mining face often affects the operation of the shearer drum
