Automatic working face complete equipment for thin seam drum shearer

Abstract

Automatic working face complete equipment for a thin seam drum shearer comprises a high-power shearer (1), a hydraulic support (2), a scraper conveyer (3), a working face centralized control system (4), a support electro-hydraulic control system (5), a working face video monitoring system (6), a working face voice communication and scram control system (7), a scraper conveyer working condition monitoring system (8), a shearer memory cutting and remote control system (9) and a ground control center (10), wherein an electro-hydraulic control system controller (5-1) and a camera (6-1) are mounted on the hydraulic support (2). The memory cutting system of the shearer memory cutting and remote control system (9) adopts a modular design and comprises four modules, i.e. a middle coal cutting module, a beveling cutting feed module, a triangular coal cutting module and a coal cleaning module, wherein the camera (6-1) can carry out tracking rotation and automatic switching according to working parameters transmitted by the shearer memory cutting and remote control system (9), meanwhile, the working face video monitoring system (6) adjusts the focal length of the camera and rotates in the vertical and the horizontal directions so as to realize the dead-corner-free monitoring of the working face.

Description

technical field [0001] The invention belongs to the field of coal mining equipment, and in particular relates to a complete set of automatic working face equipment for a thin coal seam roller shearer suitable for 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 automation 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 triangular coal cutting. Coal cleaning, unmanned or few-man mining at the working face cannot be realized
