A New Approach for Rock Strength Estimation Through a Semi-Point Load Strength Index and Correlation With Destructive and Nondestructive Tests

Volume 10: Petroleum Technology, 2022
Abstract Multi scale projects of civil, mining, and oil and gas drilling require to determine rock strength as main property of surface and subsurface rocks for safe structures, economic mining operations, as well as drilling performance optimizations. The Unconfined Compressive Strength (UCS) as a main rock strength test is considered a

Recommendation of Specimen Geometry in Determining Point Load Strength Index for Anisotropic Rocks

International Geomechanics Conference
ABSTRACT: The point load strength index (Is(50)) is the critical parameter in evaluating the mechanical response of rock. Due to its ease in specimen preparation, this index test becomes even more important for calculating the strength index of layered anisotropic rocks.

Granites of Dublin, Ireland: uniaxial compression strength, point load index and correlation analysis

Quarterly Journal of Engineering Geology and Hydrogeology
While the uniaxial compression strength ( UCS ) test is the gold standard for determining the UCS of rock for geotechnical and mining applications, empirical correlations between UCS and other test measurements such as point load index ( PLI )
