Description

Technical Field

[0001] The utility model relates to the technical field of tunnel support, in particular to a tunnel support component for underground mining. Background Art

[0002] Tunnel support parts refer to various materials and equipment used to reinforce and support underground tunnel structures. In underground projects such as underground mining, tunnels, subways, etc., tunnel support parts play a very important role in ensuring the stability and safety of underground tunnels.

[0003] Traditional tunnel support parts often use anchor mesh support and then sprayed concrete for support. However, this method requires on-site construction, and spraying concrete in the tunnel requires waiting for the concrete to solidify. At the same time, when excavating the tunnel, a combination of excavation and support is often used. Waiting for concrete takes a lot of time, resulting in reduced tunnel support efficiency. At the same time, when the concrete is not dry, there is a safety hazard of tunnel collapse. Utility Model Content
