Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, and in particular to a lighting device for a coal mining face. Background Technology

[0002] Lighting devices at coal mine longwall faces are essential equipment in coal mine production. They provide miners with the necessary working environment, ensuring that they can carry out safe production operations in the dark mine. Longwall faces generally refer to the mining faces of a mine, which usually involve multiple operational stages such as coal mining, support, and transportation. These operational stages require good lighting to ensure safety and efficiency.

[0003] However, existing lighting devices in coal mine longwall faces typically employ a fixed design, meaning the connection between the lamps and the supports or mounting bases is achieved through a fixed structure. While this fixed design can meet basic lighting needs, it lacks adjustability, preventing the lighting angle and height from being adjusted according to requirements. During coal mine longwall face operations, the working face and environmental conditions frequently change, leading to corresponding changes in lighting needs. For example, the progress of mining work can alter the required illumination range and angle, and the working face may also change to varying degrees over time. This necessitates a lighting system that can flexibly adjust the lighting angle or height. However, existing fixed lighting devices cannot meet this requirement, potentially resulting in uneven local illumination, blind spots, and insufficient lighting brightness, affecting miners' visibility and work efficiency, and even increasing safety hazards during operations.
