Bulking/Swell of Excavated or Mined Materials

List of Bulking/Swell factors for various materials. The swell factor expressed in percentage is the amount of volume increase from bank volume (undisturbed, in place state) to loose volume (disturbed, excavated state) of the material due to voids (air pockets) added to the material after excavation.

Rock cuttability assessment using the concept of hybrid

2014-10-22  Hybrid dynamic hardness (HDH) is an indentation-based rock hardness concept which is a formulated combination of the surface rebound hardness and the deformation ratio of a given rock material. This new concept was recently put forward by one of the present authors and was successfully applied to estimate the uniaxial compressive strength of carbonate rocks.
