Abstract To address critical engineering challenges such as high deformation rates, significant deformation magnitudes, and difficulties in stabilizing deep roadways, this study employs rock rheology theory to analyze the time-dependent characteristics of bolt-grouting support structures. A rheological model specifically designed to capture the deformation behavior of these structures was developed. By integrating deformation monitoring data from the surrounding rock at the Zhujixi Mine, this study elucidates the deformation mechanisms of a composite support system, comprising “bolt-shotcrete + prestressed cable/U-shaped steel + grouting” across various support stages. The findings indicate that single-component bolt-shotcrete support is insufficient for maintaining the stability of surrounding rocks in deep roadways. Conversely, a multi-component support approach effectively harnesses the load-bearing capacity of the support system to control severe deformations and mitigate catastrophic instabilities. Increasing the thickness of shotcrete significantly reduces deformation, while its compressive strength has a negligible effect. Similarly, enhancing the diameter and strength of anchor bolts, along with reducing their spacing, markedly improves deformation control. The increased material strength and decreased spacing of U-shaped steel also contribute to effective stabilization. Practical engineering applications confirm that a staged combined support strategy—comprising “bolt-net-shotcrete initial support + prestressed cable reinforcement support/U-shaped steel reinforced support + grouting reinforcement”—can effectively meet the safety requirements for large deformation control in the surrounding rock of deep roadways.
