[0002] Mining, a comprehensive energy term, is the technology and science of extracting mineral resources from within and on the Earth's surface. In a broader sense, mining also includes coal and oil extraction. The mining industry is a key raw material industry. Metal ores are the primary raw materials for the smelting industry, while non-metallic ores are important chemical raw materials and construction materials. Mining requires the use of tunnels.

[0003] Roadways are various passages drilled between the surface and the ore body, used for ore transportation, ventilation, drainage, pedestrian access, and various necessary preparatory works for the extraction of ore by metallurgical equipment. These passages are collectively called roadways.

[0004] In order to meet market demand, existing mining tunnels are generally optimized in terms of how to better mine and how to use them more conveniently, but whether they can prevent collapse is often ignored. Existing mining tunnels have the advantages of better mining effects and greater convenience for users to use them, but there are certain limitations. During normal mining, tunnels are prone to collapse after long-term use. After the collapse occurs, the tunnel cannot be supported, causing large-scale landslides. Utility Model Content
