Energy Science &Engineering, Volume 13, Issue 11, Page 5510-5524, November 2025.ABSTRACT In China, as the mining depth of coal mines increases, the occurrence conditions of coal seams are becoming increasingly complex, leading to a continuous rise in the risk of rock‐burst. The frequent occurrence of such accidents has caused severe losses to the safe production of coal mines.
