Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure.
Cibaliung Underground Gold Mine applies cut and fill mining method to optimize ore production and maintain underground stability. Existing 5 m × 5 m height and width of stope geometry has a potential new design to increase production of gold due to variety of thick ore, however serious shotcrete failures often occur in hanging wall decline.
This Table of Ball Mill Bond Work Index of Minerals is a summary as tested on ''around the world sample''. You can find the SG of each mineral samples on the other table.
The UCS of the rock is usually higher than 50 MPa. An increase of MPa is negligible compared to the inherent strength of the rock. However, the unconfined residual strength of the rock is low in most types of rocks. Therefore, an increase of MPa in the residual strength could significantly improve the postfailure behaviour of the pillar.

Mechanical failure in rocks generally means either fracturing or permanent deformation as a result of compression. While many methods for calculating failure relationships exist, an initial measure of the compressive strength of reservoir rocks is still needed for use in those calculations.
