Description

Technical Field

[0001] The utility model relates to the technical field of coal mine support, in particular to a flexible tunnel support device. Background Art

Once this phenomenon occurs, the gravel and slag on the top and side walls of the tunnel will continue to fall down. When the gravel and slag in the tunnel continue to fall down, it will affect the underground operations of the coal miners. In order to avoid such phenomena, underground workers usually install support devices in the tunnels and set up protective nets on the support devices to prevent the falling of gravel and slag, so as to increase the safety of underground operations.

[0003] For example, patent document CN218522683U discloses a flexible tunnel support device, which relates to the field of coal mine tunnel technology, and includes a U-shaped polyester fiber flexible net one and a polyester fiber flexible net two, wherein the polyester fiber flexible net two is slidably installed inside the polyester fiber flexible net one, and a side panel is fixed to the end of the polyester fiber flexible net two away from the polyester fiber flexible net one.
