Porosity–Height Relationship of Unsaturated Soil–Rock Mixtures Based on Field and Laboratory Investigations

Abstract

Abstract The stripping ratio increases as the surface mine gets deeper, causing an increase in the height of waste dump slopes. This threatens stability since dumps are composed of soil–rock mixtures, mostly in an unsaturated state. In this research, ... Practical Applications Massive waste rock dumps at surface mines can become unstable as the volume increases, but analyzing the strength of the material deep inside is difficult, expensive, and potentially unsafe. This study presents a new, cost-...
