Overhead Anchor Reinforcement Technology

Overhead Anchor Reinforcement Technology 

Overhead Anchor Reinforcement Technology means that when the roadway is arranged in the broken coal rock body or the direct top of the roadway is a weak laminar structure, before the excavation of the surrounding rock, anchor support technology is used to support the roadway surrounding rock that will be exposed in advance, so that after the excavation of the roadway and the destruction of the original rock stresses, the integrity of the surrounding rock of the roadway is maintained, and the stability of the top coal of the broken region of the coal rock body and the coal wall of the two gangs is enhanced in the excavation process, so as to provide time and space guarantee for the permanent support before the roof plate leaves the stratum, and to prevent the deterioration of the support conditions caused by the roadway flake gangs. Provide time and space guarantee for the completion of permanent support before the roof plate leaves the layer, and prevent the deterioration of support conditions caused by the roadway sheet gang.
