Description

Technical Field

[0001] The present invention relates to the technical field of coal mining, in particular to a special rail vehicle for underground coal mine transportation. Background Art

[0002] Coal mines require track during the mining process. Tracks provide a stable path for mine carts, enabling efficient transportation of coal, gangue, and various production materials to the surface or other designated locations. The efficiency and stability of rail transportation help improve the overall production efficiency of coal mining. The track system allows coal and materials to be transported quickly between underground and the surface, reducing transportation time and labor costs, making the coal mine's production process smoother, and thus improving the mine's economic benefits.
