Automatic cutting control method for demonstration and reproduction of underground thin coal seam shearer with wind direction

Abstract

The invention discloses a coal cutter teaching and reproduction automatic cutting control method for a downhole thin coal seam with the wind direction. The method comprises the following steps that firstly, a drum coal cutter automatically cuts the coal seam for teaching; and secondly, the drum coal cutter automatically cuts the coal seam for reproduction, specifically, 201, a control system of the drum coal cutter is initialized, 202, whether the drum coal cutter is located at an end or not is judged; 203, the left end of the drum coal cutter automatically cuts the coal seam for reproduction, and 204, the right end of the drum coal cutter automatically cuts the coal seam for reproduction. The cutting process of the downhole thin coal seam with the wind direction through the drum coal cutter is taught, the necessary processes of beveling cutter inlet, triangular coal cutting, float coal removing and coal cutting and collecting during advancing of the downhole thin coal seam with the wind direction are covered, manual interference is greatly reduced, the automatic coal cutting requirement of the coal cutting technique for the downhole thin coal seam with the wind direction 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 mining machines, and in particular relates to a teaching and reproduction automatic cutting control method of an underground 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 technology...

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
