Problems solved by technology
Blindly increasing the prestress of the anchor (cable) will reduce the stability of the anchor (cable) and cause it to be broken in advance. Smaller prestress will make the anchor (cable) weaker in controlling the surrounding rock , it is difficult to achieve the control effect
Moreover, the existing support technology cannot adjust the anchoring force of the bolt after the installation of the bolt (cable), the deformation space of the surrounding rock is small, the stress of the surrounding rock of the roadway is easy to concentrate, and it is easy to cause the instability of the surrounding rock of the roadway

The invention belongs to the field of mining engineering, in particular to an automatically controlled anchor rod and anchor cable device and method. It includes a rock formation support plate and a hydraulic support support plate. A hydraulic support is supported between the rock formation support plate and the hydraulic support support plate. The hydraulic support is connected to the hydraulic system through a hydraulic pipeline. There is a hole in the middle of the supporting plate, where the anchor rod or anchor cable of the hydraulic support supporting plate passes. On the bracket supporting plate, the upper end of the anchor rod is anchored in a hard and thick rock formation or a complete rock formation. In the present invention, the hydraulic support installed on the supporting plate of the hydraulic support can actively support the roof of the roadway and adjust the anchoring force of the roadway, so as to effectively protect the stability of the surrounding rock of the roadway.
Description
technical field [0001] The invention belongs to the field of mining engineering, in particular to an automatically controlled anchor rod and anchor cable device and method. Background technique [0002] Anchor (cable) is the main technical method of roadway support in my country at the present stage. The anchor (cable) is fixed in the hard and thick rock formation (or stable rock formation) with anchoring agent, and is assisted by the anchor (cable) supporting plate and steel belt. The equipment controls the deformation and breaking of the soft rock formation on the anchor side of the hard and thick rock formation (or stable rock formation). In order to ensure the control effect, the existing technical measures are to apply prestress to the bolt to promote the weak surrounding rock of the roadway to form a stable stress structure, but this method fails to accurately control the stress of the surrounding rock of the roadway. Blindly increasing the prestress of the anchor (cab...
