System and method for automatically controlling coal mining machine and automatically straightening working face on basis of video inspection

Abstract

The invention discloses a system and a method for automatically controlling a coal mining machine and automatically straightening a working face on the basis of video inspection. The system comprisesthe coal mining machine and a hydraulic support which are arranged on the working face, an inspection rail arranged in the stretching direction of the working face, and an inspection device, wherein the inspection device is slidably mounted on the inspection rail; the inspection device is used for detecting coal-rock interface data and the working face straightness, and outputting a control instruction according to the coal-rock interface data and the working face straightness; the coal mining machine performs automatic coal cutting control according to the control instruction; the hydraulic support performs automatic working face straightening control according to the control instruction. After the adoption of the system and the method, influence of a production environment with a severefully mechanized coal mining working face on a video system can be avoided, the number of working face cameras is reduced, and working face coal-rock interface identification and working face straightness detection are completed.

Description

technical field [0001] The invention relates to the technical field of automatic mining of top-coal caving working faces in underground coal mines, in particular to a system and method for automatic control of shearers and automatic straightening of working faces based on video inspection. Background technique [0002] With the development of coal mine automation and intelligent technology, the fully mechanized mining face has realized the production mode of automatic production of working face equipment, monitoring center and ground remote control, mainly based on the memory cutting of coal shearer, hydraulic support and machine automatic control, but Due to the continuous change of coal mine conditions, this method of production, after continuous multi-knife operations, due to the influence of changes in the coal seam, the memory coal cutting curve must be revised again to ensure continued normal production. The accumulation of sensor errors and the pin lug error between t...

[0002] With the development of coal mine automation and intelligent technology, the fully mechanized mining face has realized the production mode of automatic production of working face equipment, monitoring center and ground remote control, mainly based on the memory cutting of coal shearer, hydraulic support and machine automatic control, but Due to the continuous change of coal mine conditions, this method of production, after continuous multi-knife operations, due to the influence of changes in the coal seam, the memory coal cutting curve must be revised again to ensure continued normal production. The accumulation of sensor errors and the pin lug error between the hydraulic support and the scraper conveyor will cause the working face to be uneven, which cannot meet the straightness requirements of the coal mine safety regulations on the working face, and must be stopped for straightening control of the working face
