Automatic coal caving control system of fully mechanized caving face

Abstract

The invention provides an automatic coal caving control system of a fully mechanized caving face. Video cameras are integrally embedded onto tail beams of hydraulic brackets; when one of the hydraulicbrackets caves coal, a bracket controller of the hydraulic bracket in an upwind head position controls the video camera to screw out, air in the upwind head position is clean, a video signal collected by the video camera is high in definition and the video camera monitors a coal caving process of the hydraulic bracket which carries out coal caving, and the controller controls the video camera toscrew in after coal caving, so that problems that the video camera is smashed, bumped and collided by large coal and the lens of the camera is polluted severely by dust in a using process of a top coal caving working surface of the video camera and the like are solved. Meanwhile, the bracket controller can control coal caving operation of the hydraulic bracket automatically according to video information shot by a first camera and a second camera in the video camera, so that unmanned control is achieved, and the degree of automation and the safety of the coal caving process are improved.

Description

technical field [0001] The invention relates to the technical field of automatic coal mining, in particular to an automatic coal discharge control system for a fully mechanized caving face. Background technique [0002] In coal mine production, the production environment of the working face is harsh, and the health and safety of the staff are often not guaranteed. A large amount of dust generated during the mining of the working face has caused great harm to the physical and mental health of the working face workers. At present, through the automatic control of the hydraulic support and the coal mining machine, the coal mining face has realized the mining of the working face with few people or even no one. Due to major technical problems such as identification of coal and gangue on the coal discharge face, there is no effective way to observe the coal discharge at the rear. The camera installed on the tail beam is often scraped off by the materials on the rear scraper convey...
