Working-face automated integrated control system for thin seam drum shearers

Abstract

A working-face automated integrated control system for thin seam drum shearers comprises a working-face central control system (4), an electrohydraulic support control system (5), a working-face video monitoring system (6), a working-face voice communication and scram control system (7), a whole-set conveyer equipment monitoring system (8), a shearer memory cutting and remote control system (9) and a ground control center (10), and electrohydraulic control system controllers (5-1) and cameras (6-1) are mounted on hydraulic supports. The working-face central control system (4) utilizes a data coupler to convert the data formats of the different control systems into a format in order to carry out unified control, and carries out two-way real-time data communication between a working face shearer, the hydraulic supports and a scraper conveyer, the cameras (6-1) carry out tracking rotation and automatic switching according to the working parameters sent by the shearer memory cutting and remote control system (9), meanwhile, the working-face video monitoring system (6) is utilized to adjust the foci and vertical and horizontal rotation of the cameras (6-1), and thereby the dead corner-less monitoring of the working face is realized.

Description

technical field [0001] The invention belongs to the field of coal mining equipment, and in particular relates to an automatic integrated control system for a thin coal seam roller shearer working face adapted to thin coal seam mining under complex geological conditions. Background technique [0002] my country's thin coal seam resources are abundant and widely distributed. Thin coal seam reserves account for a large proportion of the total coal reserves, and the proportion of thin coal seam reserves in state-owned coal mines alone accounts for about 20%. Because many mines in China do not follow scientific mining procedures, "eat fat and lose thin, mine thick and discard thin", and thick coal seams are mined prematurely, resulting in substantial damage to the original occurrence and continuity of thin coal seams overlying them within a certain range. The problem that these resources cannot be recycled is very serious. Establishing the awareness of resource urgency and the ...

Problems solved by technology

However, at present, the complete set of automatic equipment for the thin coal seam roller shearer working face developed at home and abroad only realizes the automatic mining of the middle part of the working face, while manual intervention is required at both ends of the working face for oblique cutting and cutting of triangular coal, Coal cleaning cannot realize unmanned or few-person mining at the working face. At the same time, the el
