Design of Initial Mining Pressure Relief Scheme for Large‐Size Mining Face: A Case Study

Engineering Reports, Volume 8, Issue 4, April 2026.
The numerical simulation analysis method is used to compare the actual mining face (315 m) with the designed mining face (200 m). The results show that the large mining height working face has larger abutment pressure peak and stress concentration factor than the general mining height working face.
