Robust Range-Doppler Acoustic Feature Fusion for Unauthorised Personnel Crossing Detection on Underground Belt Conveyors

Unauthorised personnel crossing underground belt conveyors poses a serious safety risk in coal mines. To improve the reliability of non-contact crossing detection under complex acoustic interference, this paper proposes an acoustic sensing method based on distance–velocity feature fusion. An adaptive acoustic interfere...

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...
