Title:
DISTRIBUTED COAL CUTTING APPARATUS FOR COAL MINING WORKING FACE OF COAL MINE
Document Type and Number:
WIPO Patent Application WO/2023/206695
Kind Code:
A1
Abstract:
Disclosed is a distributed coal cutting apparatus for a coal mining working face of a coal mine,comprising a coal mining unit. The coal mining unit comprises a set of coal mining machines and two sets of hydraulic supports, the two sets of hydraulic supports being arranged side by side, the arrangement direction of the two sets of hydraulic supports being parallel to the coal wall of the coal mining working face, and the coal mining machines being connected to one set of the hydraulic supports. In the present invention, multiple sets of coal mining machines simultaneously perform a coal cutting process, changing from single-point cutting to simultaneous multi-point coal cutting. Coal cutting production capacity and efficiency are significantly increased, allowing for the possibility of multiple control modes for multiple sets of coal mining machines, and improving production flexibility and adaptability. Each set of coal mining units comprises a set of coal mining machines and two sets of hydraulic supports. The hydraulic supports are capable of providing support to the top plate of the working face, while the coal mining machine is connected to the hydraulic support in a rotatable manner. This allows for adjustment of a coal mining machine working angle, enabling the coal mining machine to perform coal cutting operations within the range of the adjacent hydraulic supports. If multiple sets of coal mining units are provided, the efficiency of coal mining operations may be improved.
