Implication

Randomized trial investigates failure mechanisms and control technologies for soft rock roadways, suggesting effective deformation management.

Key Points

This research aims to explore the causes of deformation failure in deep high-stress fractured soft rock roadways and propose effective control technologies.
Conducted mechanical property tests and mineral composition analysis on surrounding rock.
Performed in-situ stress tests to investigate failure mechanisms and control strategies.
Utilized similar simulation to evaluate stress distribution and deformation characteristics under coupling conditions.
Identified main causes of deformation: high in-situ stress, high clay content (> 50%), mining-induced stress, and lack of support-rock coupling.
Demonstrated excellent bearing performance of concrete-filled steel tubular supports under high static loads.
Field monitoring indicated maximum roof subsidence of 51 mm, floor heave of 106 mm, and side convergence of 77 mm.
