Identification of Unstable Rock Blocks and Rockfall Hazard Assessment on a Karst Steep Rock Slope Using UAV Photogrammetry

Steep rock slopes are widely distributed in the karst mountainous regions of southwestern China, where structurally controlled rockfalls frequently threaten transportation infrastructure and human safety. Accurate identification of unstable rock blocks (URs) and quantitative asse...

Damage evolution of coal under SHPB impact and multi-scale simulation

As energy exploitation advances, operations are increasingly moving into deep coal seam regions. Understanding the dynamic mechanical properties of coal seams under complex stress conditions in such deep-seated environments has become a key focus in mining engineering. In this st...
