ANSYS Simulating Analysis of 3D Single-Cable Temperature Model of Fully Grouted Cable Bolts
By using advanced engineering simulating analysis software ANSYS, the 3D single-cable temperature model based on the in-situ experiment of reinforcement with fully grouted cable bolts in the high-temperature stope hangingwall of Dongxiang Copper Mine in China is established and analyzed in order to explore the rock anchoring mechanism of a single fully grouted cable bolt in high-temperature environment. The results show that most surrounding rock stress is borne by tendon. Staggered movement and separation would appear more easily between tendon and grout than between grout and surrounding rock. Deformation between steel and grout and that between grout and rock are harmonious. No separation appears and the bond strength of fully grouted cable bolts is enough in the case of Dongxiang Copper Mine. These conclusions are beneficial to underground deep mining and mine extraction at the risk of spontaneous combustion of ore.
