Discussion

Field monitoring reveals enhanced stability in goaf-side roadways with a new synergistic support approach, indicating improved mining safety.

Horizontal displacement on the coal pillar side decreased by 89.5% due to a new control method, ensuring roadway stability.
Vertical displacement reductions reached 45.8% on the coal pillar side, highlighting the method's effectiveness in deep mining conditions.
Numerical simulations using FLAC3D demonstrated significant improvements over traditional support approaches in controlling roadway deformation.
The proposed method includes roof blasting and coal pillar reinforcement, showing feasibility and effectiveness in actual field applications.

Zhang et al. (2025) studied this question.
