Description

A separate type of temporary support equipment for fully mechanized roadway

technical field

The utility model relates to a separate type of temporary support equipment for fully mechanized excavation tunnels, which belongs to the technical field of mine support equipment.

Background technique

At present, the support of the fully mechanized excavation roadway in our country has generally adopted the bolt support as the permanent support, and before the bolt support, the temporary support must be carried out to prevent the roof from falling off the excavation face. At present, the temporary support of coal mines generally adopts multiple front exploration beams suspended along the direction of the roadway on the roof supporting anchor rods and probed to the empty roof area, which can protect the roof and prevent personal casualties caused by roof fall. The disadvantages of this support method are: (1) the front probe beam has no initial support force for the support of the empty roof area, and the safety and reliability are poor; (2) the operation process is complicated, relying on manual work, the support time is long, and the temporary support Low efficiency; (3) The operator must enter the empty roof area to carry out erection operations, which has a great potential safety hazard.
