Investigation reveals that effective support technologies improve principal stress management in roadway, suggesting enhanced stability approaches for mining areas.
Key Points
Significant deformation occurs in surrounding rock due to high horizontal tectonic stress and soft rock characteristics.
Principal stress evolution monitored from excavation to completion provides insights into roadway conditions.
Assessment using laboratory tests and numerical simulations supports development of innovative stabilization techniques.
Proposed support scheme enhances stability control in mining areas, highlighting the importance of effective interventions.
