Control method for demonstration and representation of automatic cutting of drum shearer

Abstract

The invention discloses a control method for demonstration and representation of automatic cutting of a drum shearer. The method comprises steps as follows: step 1, demonstration of automatic cutting of a drum shearer on the medium-thickness coal seam; step 2, demonstration of automatic cutting of the drum shearer on the low-coal-dust thin coal seam; step 3, demonstration of automatic cutting of the drum shearer on the high-coal-dust thin coal seam in the ventilation direction from right to left; step 4, demonstration of automatic cutting of the drum shearer on the high-coal-dust thin coal seam in the ventilation direction from left to right; step 5, representation of automatic cutting of the drum shearer: 501, acquisition of initialization data of a coal seam working face; 502, judgment of the type of the coal seam; 503, representation of automatic cutting of the drum shearer on the medium-thickness coal seam; 504, representation of automatic cutting of the drum shearer on the low-coal-dust thin coal seam; 505, representation of automatic cutting of the drum shearer on the high-coal-dust thin coal seam in the ventilation direction from right to left; 506, representation of automatic cutting of the drum shearer on the high-coal-dust thin coal seam in the ventilation direction from left to right. With the adoption of the method, multiple coal seam cutting processes are demonstrated, automatic coal mining requirements of different coal mining technologies are 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 mining machines, and in particular relates to a teaching and reproduction automatic cutting control method of a drum 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 developed rapidly and has become...

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
