Embodiment Construction

[0012] The instruments and equipment in the specific embodiment of the present invention are equipment well known to those skilled in the field of coal mining technology, and can be obtained by purchasing.

[0013] Such as figure 1 As shown, the unmanned working face in the thin coal seam adopts the longwall and retreating method for mining. The main coal mining equipment in the working face 15 is composed of a scraper conveyor 7, a hydraulic support 8 and a shearer 10; the hydraulic support 8 faces the The direction of the shearer 10 is the coal seam 6, and the direction of the hydraulic support 8 facing away from the shearer 10 is the goaf 9; the shearer 10 moves back and forth on the scraper conveyor 7 for coal cutting and coal loading, and the hydraulic support 8 pushes The scraper conveyor 7 moves forward, pulls the frame, pushes and slides, and pushes the working face forward for mining; the control center 1 and the trough controller 3 form a wired network through the op...

Abstract

The invention discloses a drum-coal-mining-machine-based thin coal seam unmanned automated mining technology. The technology has the characteristics that: persons do not exist on an operating surface; operators know about conditions of the operating surface through video in a control center far from the operating surface and simultaneously complete various kinds of operation; video signals and control instructions are transmitted through a wireless switch; a coal mining machine has a function of memory cutting and is provided with a position monitoring device and an infrared transmitter at the same time, coal is automatically cut according to a preprogram, and operation parameters such as positions, directions and the like are sent out at any time; a bracket controller receives the parameters, automatically drives an electric hydraulic control valve to do actions of column lowering, frame moving, pushing, column erecting and the like according to the preprogram, and a hydraulic bracket is pushed to move forward along with the coal mining machine, so that the unmanned automated mining on the operating surface is realized; and when the thickness of coal seams, and top and bottom boards are changed, the operators regulate operation programs and the parameters in the control center and perform manual intervention on the coal mining machine and the hydraulic bracket, so that the remote-control unmanned automated mining on the operating surface is realized.

Description

technical field [0001] The invention relates to a quasi-unmanned automatic coal mining mode for a thin coal seam, in particular to a quasi-unmanned automatic coal mining method for a working face with a coal seam thickness of 0.8-1.3m. Background technique [0002] A thin coal seam refers to a coal seam with a thickness of 0.8-1.3m. my country's thin coal seam resources are abundant and widely distributed. Among the proven mining areas, 84.2% of the mining areas have thin coal seams, and the recoverable reserves of thin coal seams are 6.15 billion tons, accounting for about 19% of the total recoverable reserves, of which 0.8-1.3m gently inclined thin coal seams account for about 73.4%. Due to the narrow working space of thin coal seam mining, coal mining, coal loading, coal transportation, and equipment installation and operation are extremely difficult, and the problems of low equipment, small size, high power, and high automation required for high production and high effi...
