Monitoring the Hydraulic Conductivity of Crushing Sands

from crushing of sands subjected to large stresses. Results show that the hydraulic conductivity degradation curve is dependent on sand type, in particular the particle shapes and mineral composition. The role of arching on the compression behavior and the associated post-crushing grain size distribution curves is also addressed.

Sandstone | Minerals Education Coalition

Once drained, the sand reports to a plant. Well-consolidated deposits can be mined using conventional drill-and-blast methods. Once blasted, the sandstone is "mucked" using a front-end loader, placed into haul trucks, and transported to a primary crusher. Following crushing, the material may report to a secondary or tertiary crushing plant.
