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. C 0 can be estimated from porosity or sonic velocities, but many .From Rock & Stone Crushing, Stump Mulching, Soil Shredding, to Soil Stabilization, and Asphalt Pulverizing/Grinding, Valentini Crushers have been CRUSHING IT for decades!!!
