Mining-Sequence Effects on Slope Deformation and Stress Redistribution During Cemented Backfill Mining of Multiple Extra-Thick Coal Seams Beneath an Open-Pit Highwall

Cemented backfill mining has become an effective approach for recovering coal resources beneath open-pit highwalls while maintaining slope stability. However, the repeated extraction of multiple extra-thick coal seams induces complex overburden responses, and the effects of minin...

Intelligent Ore Sorting Method Based on Multi-Feature Fusion of Dual-Energy X-Ray Responses

The conventional attenuation-ratio feature R remains affected by particle thickness, material heterogeneity, and beam hardening in practical dual-energy X-ray transmission (DE-XRT) measurements. This study proposes an ore-sorting method based on multi-feature fusion of dual-energ...
