Analysis of Stress Evolution Characteristics and Mine Pressure Patterns During Roadway Excavation Under Irregular Goaf Areas
To clarify the stage-dependent stress superposition in gob-side roadways beneath irregular overlying goafs, the #52109 material roadway was investigated using a MATLAB-based analytical stress-transfer model, key-strata mechanics, FLAC3D simulation, and field monitoring. The analytical results revealed an approximately...
