A Coal Mining Control Method for Coal Shearer with Automatic Coal Cutting as Main and Remote Intervention as Supplement

Abstract

The invention discloses a coal mining machine coal mining control method with automatic coal cutting being primary and remote interference being auxiliary. A coal mining machine is a double-roller coal mining machine. A control system adopted by the method comprises a controller, a wireless communication module, a control computer, a data storage device, a camera, a displacement sensor, a left rocker arm angle sensor and a right rocker arm angle sensor. The coal mining machine mining control method comprises the following steps that first, demonstration is conducted manually; and second, the coal mining machine is controlled to conduct coal mining with automatic coal cutting being primary and remote interference being auxiliary, specifically, in the automatic coal cutting process through the coal mining machine, when an operator judges that the posture of the coal mining machine needs to be adjusted manually, the operator conducts manual interference control to adjust the coal cutting posture of the coal mining machine, and after adjustment is completed, remote manual interference is stopped, and the automatic coal cutting posture of the coal mining machine restores. According to the coal mining machine coal mining control method with automatic coal cutting being primary and remote interference being auxiliary, the steps are simple, the design is reasonable, the method is convenient to implement, the purposes of staff reduction and efficiency improvement are achieved, the safety coefficient is increased, the practicality is high, and popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the technical field of coal mining machine control, and in particular relates to a coal mining control method of a coal mining machine with automatic coal cutting as the main and remote intervention as the supplement. Background technique [0002] my country's thin coal seam has abundant recoverable reserves, relatively stable storage conditions, and good coal quality. In recent years, the mining of thin coal seams has gradually increased, and thin coal seams have gradually become the main coal mining seam. But at present, the degree of mechanization applicable to thin coal seam and thin coal seam mining is still relatively low, most of which are mined by blasting, the recycling rate and efficiency of resource mining are low, and there are many accidents, the working environment of workers is harsh, and the labor intensity is very high High, great potential safety hazard. Thereby along with increasingly paying attention to thi...
