[0002] The mining industry refers to the mining of naturally occurring solid minerals such as coal and minerals, including both above-ground and underground mining. Currently, the mining industry is relatively developed and is generally carried out by one or more mining workshops and some auxiliary workshops. During the process of ore mining in mines, the stones on the ore may roll down and form falling rocks. Therefore, safety protection devices need to be installed at corresponding locations in the mines. Generally, a protective net structure is used for safety protection to prevent surrounding residents from mistakenly entering the mining area and causing losses to people’s lives and property.

[0003] For example, the announcement number is: CN218479832U, a mine rockfall prevention safety protection device, which belongs to the field of protection devices, includes a fixed rod, a connecting steel rope is connected to the fixed rod, and a protective net is arranged on the connecting steel rope, a connecting structure is arranged between the connecting steel rope and the fixed rod, and the connecting structure includes a connecting seat and a connecting rod, the connecting seat is arranged on the fixed rod, the connecting rod is arranged on the connecting steel rope, and the connecting rod is connected to the connecting seat, a pulling structure is installed on the fixed rod, and the pulling structure includes a fixed seat and a steel wire rope, and the fixed seat is connected to the steel wire rope. Through the setting of the connecting structure, the connection between the protective net and the fixed rod can be quickly realized, the installation speed can be improved, and the stability after installation can be guaranteed at the same time. The pulling structure adopts a detachable structure, which can ensure the pulling effect during installation, and can be quickly disassembled when the device is not needed. The structure is simple and the operation is convenient and fast.

[0004] When using common mine safety protection devices, although they can buffer and block falling rocks by setting up protective nets, and are also convenient for installation and disassembly, after rolling stones hit the protective nets many times, the protective net grids are easily damaged or broken, and they need to be frequently repaired or replaced, which increases the cost of safety protection.
