Abstract: Due to its special hollow structure, the ultimate bearing capacity of hollow grouting anchor cable is reduced by more than 30% compared with the common solid anchor cable, which is difficult to meet the support requirements of deep tunnels in complex stress environment. The 2060mpa high-strength hollow grouting anchor cable has been studied and developed. After laboratory and field measurements, its ultimate bearing capacity has reached more than 660kn, and the mechanical essence of its tension dispersion type has been pointed out. In order to avoid the shear failure of the anchor cable caused by the horizontal movement of the roadway roof strata, the cooperative support technology of high-strength hollow grouting anchor cable and linear anchor cable bundle is proposed, and the cooperative support mechanism of the two support structures is explained. Taking the 1127 (1) transportation trough floor roadway repair project in Guqiao Mine as the background, the field test of the cooperative support technology of high-strength hollow grouting anchor cable and linear anchor cable bundle is carried out. The application results show that this technology can effectively control the large deformation of surrounding rock in deep high pressure roadway, and it is an effective roadway reinforcement method.
