The effects of gravel cushion particle size and thickness

Abstract Gravel cushions are widely used to absorb the im pact energy of falling rocks in open pit mines A particularly important application is to enhance the energy absorbing ca pacity of rockfall sheds In this paper we study how varying the thickness and particle size of a gravel cushion influences its energy consumption and buffering
