[0002] Mineral resources are distributed in mountainous areas with complex geological environments. Coupled with natural erosion and crustal movement, as well as changes in rock and soil caused by later mining, mining construction is extremely risky. Once safety risks are encountered during mining construction, the lives of construction workers will be directly threatened. In order to avoid construction safety accidents, safety boards are usually used to protect the top of the mine to prevent falling objects.

The utility model can enhance the connection strength between the safety plate and the mine hole and the support strength of the safety plate, prevent falling, and improve the protection effect of the safety plate.

[0004] However, the above patent is inconvenient to disassemble and assemble, and can only be fixed at a specific position in the mine. Therefore, one protective device can only provide safety protection for a small section of the mine, and it is not convenient to transfer with the mining operation. If you want to achieve all-round protection of the mine, the cost is relatively high. Utility Model Content
