Behavior of anchor cable bolts with c-shaped tube and cable bolts in shear test

Abstract: The gradual development of coal mining in deep areas has brought new challenges to the surrounding rock support system. It is imperative to design surrounding rock support elements that exhibit strong tensile and shear resistance and are suitable for pretension load. In this paper, an anchor cable bolt with a c-shaped tube (ACC) is proposed, and in order to study the shear performance of the ACC, the mechanical properties of the ACC and ordinary cable bolts with various diameters and pretension loads are teste… Show more

“…However, the breakage of anchor cables in Chinese coal mines has occurred in the unanchored section. Shan Renliang et al 25 developed a new type of anchor cable with a C-shaped tube (ACC), which can effectively solve the problem of breakage of the unanchored section of the anchor cable.…”

“…Although a hardened anchoring agent wraps the cable bolt to provide greater lateral resistance, this technology extends the construction process, while anchorage interfacial adhesion limits the axial tensile load transmission of the CBFS [27]. Shan et al [28][29][30] proposed a pipe-cable composite structure (anchor cable with a C-shaped pipe) and reported that this structure could effectively improve the overall shear capacity of the structural plane. Kang et al [31] reported that, by increasing the cable diameter and changing the cable structure, a strong and high-elongation cable bolt can effectively control the expansion deformation of surrounding rock in the anchorage zone.…”

“…In Sect. 5, a speci c support strategy and scheme based on a new support technology of anchor cable with c-shaped tube (ACC) [24,25] are proposed, and the support effect is veri ed by numerical simulation and eld application. The research results of this paper show the in uence of the change in coal seam thickness on the stability of roadways and preliminarily analyse the reasons.…”
