Intelligent teaching-free memory cutting system and method for fully mechanized caving face coal mining machine

Abstract

The invention relates to an intelligent teaching-free memory cutting system and method for a fully mechanized caving face coal mining machine, and belongs to the field of intelligent mining of coal seams. The cutting system comprises the coal mining machine and a hydraulic support; and the coal mining machine works according to a fully mechanized caving face, the fully mechanized caving face is divided into 22 quadrant areas, in addition, data of the 22 quadrant areas of the fully mechanized caving face is established, and the coal wall is circularly cut in the 22 quadrant areas of the fully mechanized caving face through the electric traction coal mining machine. According to the intelligent teaching-free memory cutting system and method for the fully mechanized caving face coal mining machine, the coal mining machine can memorize the cutting parameters of the coal wall cut before and automatically correct the cutting parameters of the coal wall to be cut next, the coal wall is automatically controlled to be cut, and therefore the automatic control capacity of the coal mining machine is improved; and the fault rate of the coal mining machine is decreased, the operation rate of the coal mining machine is increased, and the production safety and the effective efficiency are further improved.

Description

technical field [0001] The invention relates to an intelligent fully mechanized caving face coal shearer cutting system and method without teaching memory, belonging to the field of coal seam only mining. Background technique [0002] In the intelligent fully mechanized caving face of the coal mine, the shearer is the main coal mining equipment in the coal mine, and its degree of automation and intelligence determines the efficiency of coal mining. In the coal mining face of the coal mine, the left and right drums of the electric traction shearer rotate at the same time to cut coal, and the shearer moves left or right along the direction of the coal wall. During the continuous movement of the shearer, the shearer The cutting drum rotates continuously to cut coal, and the rotating drum cuts the coal from the coal wall and falls to the front scraper conveyor at the bottom of the shearer, and the front scraper conveyor will cut the coal Ship out. [0003] The typical cutting ...

AI Technical Summary

Problems solved by technology

Due to the complex working conditions of the fully mechanized caving face in the coal mine and the differences in the experience of the operators, it is difficult to satisfy the need for accurate control of the shearer.
