Correlations of Bond and Breakage Parameters of Some Ores with the Corresponding Point Load Index

Particle and Particle Systems Characterization, 2012
AbstractThis paper presents significant correlations of the Bond parameter (work index, Wi and grindability, G) and the breakage parameters (specific rate of breakage, Si and the fineness value, γ) with the point load index (Is(50)). The experimental results obtained from calcite, barite, colemanite and bauxite samples have demonstrated that the Bond ...

An assessment on the correlations between uniaxial compression strength and point load index

Arabian Journal of Geosciences, 2022
Point load index (Is) has been commonly used for predicting uniaxial compressive strength of intact rocks (UCS) because Is is easy and quick test performed on lump specimens.

Investigation of Point Load Index Using Novel Discrete Based Model

Applied Mechanics and Materials, 2016
In this study, a micro-mechanical model is developed to study the correlation of the point load index in rocks with uniaxial compressive strength (UCS) tests. The model is represented by an array of bonded particles simulated by a novel discrete based model, which was introduced by the authors previously.

The Use of the Point Load Index in Weak Carbonate Rocks

1985
There has been increasing use of the point load index as a measure of rock strength since its introduction in 1972. The test results have been correlated to in the uniaxial compressive strength σf of the rock. The correlations between the rates of point load index Is and the uniaxial strength σf for conventional strong rocks are σf/Is = 16 to 24.
