Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of roadway support, and particularly relates to a non-coal mine non-ferrous mine roadway support device. BACKGROUND

[0002] The non-ferrous mine refers to a mine for mining non-ferrous metal mineral resources such as copper, aluminum, lead, zinc, nickel, cobalt, tungsten, tin, antimony and molybdenum. Roadway support is a core link for ensuring safety and efficiency in underground engineering such as mines and tunnels. After roadway excavation, the original stress balance of rock mass is destroyed. Support such as anchor rods and steel frames is used for active or passive reinforcement to prevent roof fall, rib spalling and other accidents. For example, the suspension effect of anchor rods can fix loose rock layers on stable rock mass.

[0003] The existing roadway support structure can only provide a single support function. When slight deformation occurs in the roadway, the traditional support device cannot sense it in time and issue an alarm, so that the staff cannot take reinforcement measures in time.
