Mechanism of Mining-Induced Dynamic Loading in Shallow Coal Seams Crossing Maoliang Terrain

open access: yesApplied Sciences
To address the intense mining pressure and dynamic accidents, such as shield collapse during mining in shallow coal seams crossing the Maoliang terrain, this study focuses on Panel 30206 of the Yanghuopan Coal Mine. Through theoretical analysis, numerical simulation, and field measurements, the stress transfer patterns and dynamic changes in shield ...
