This study investigates the failure and energy dissipation patterns of tuff under impact loads with varying occurrence conditions in Dahongshan Copper Mine through Split Hopkinson pressure bar (SHPB) tests, digital image...

This study proposes a deep-hole directional blasting technology based on polymer energy charge packages for roof cutting and pressure relief as a solution to difficult roadway support and poor stability of coal pillars d...

This study investigates the dynamic mechanical response and energy dissipation mechanism of ore rock with different grades from the Baiyun Ebo West Mine under impact loading. Ore rock samples were taken for dynamic mecha...

Understanding the strain-damage-energy dissipation mechanisms and evolution characteristics of deep coal and rock under impact loading is of great significance for the prevention and control of rockbursts. In this study,...
