The experimental results show that the fine particles production is considerably affected by confining stresses, even at low values (100 kPa), and also by grain geometry. The experimental results show also that the fine particles production increase with the strain level during the shearing test. UR - https://revues.univ-biskra.dz/index.php/jaest/article/view/1894
