Description

Technical Field

[0002] Mine tunnel protection belts are a type of safety equipment used to protect workers in mines from falling rocks, collapses or other dangerous objects. Mine tunnel protection belts are usually made of high-strength materials such as wire ropes or polyester fibers and are fixed to the top or side walls of the mine tunnel; they can prevent rock blocks from falling and provide additional support and protection to ensure the safety of workers; mine tunnel protection belts can also be used to indicate the boundaries of the mine tunnel, reminding workers not to cross the boundary, and in some cases, can be used to isolate different work areas to ensure the safety of the working area; in short, mine tunnel protection belts play a protective and warning role, helping to reduce the occurrence of mine accidents and ensure the safety of workers.

[0003] Some existing mine tunnel protection belts mostly use some simple isolation plates as protection belts. These isolation plates are only connected by simple connection structures, which have defects in stability and durability. When vibration occurs in the mine tunnel, the gravel on the top wall of the mine tunnel collapses, which can easily injure workers. At the same time, the inner wall of the underground mine tunnel is prone to water seepage, and water drips from the top of the head, which can easily interfere with the line of sight and affect mining work.
