Compressive strength of rocks PetroWiki

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0). Lithology is commonly derived during log analysis, so m may be estimated (Table 1). What is needed still is an initial measure of rock strength provided by C 0.

Uniaxial Compressive Strength an overview

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.

1. Introduction. The determination of basic mechanical properties of rocks is crucial to a specific engineering project. Several mechanical properties, including uniaxial compressive strength (UCS), have become widely accepted parameters for rock design projects (Baskerville, 1987).From past to present, direct and indirect methods have been used to determine UCS of rocks in field and laboratory.
