Short summary
Gravel cushions are widely used for rockfall prevention in open-pit mines to absorb energy; the energy-consumption and buffer mechanism of different thicknesses and particle sizes of gravel cushions under the impact effects are studied. A series of laboratory tests for different cushions are conducted, combining the blocks' volume and drop height. It provides a theoretical and practical basis for the wide application of cushion design to control rockfall.
