A mineral-strength conversion model based on LIBS technology and rapid batch testing and application of uniaxial compressive strength

Meitan xuebao
Due to the complexity and abruptness of deep engineering disasters, the mechanical parameters of rocks, particularly uniaxial compressive strength (UCS), play a critical role in stability analysis, risk assessment, support parameter optimization, and ...

Effects of Different Ratios of Fly Ash and River Sand on Mechanical Properties of Cemented Paste Backfill Materials

Advances in Civil Engineering
The mechanical properties of cemented paste backfill (CPB) are crucial for stope safety. Some mining areas in the Yellow River basin face a shortage of coal gangue, and these areas have abundant river sand (RS) resources.
