The point load strength index is a widely used index in rock engineering, and cylindrical core and irregular shaped specimens are used in its determination. But, in mine sites, the borehole cores are cut axially into two equal parts to obtain half-cu

The invasion created by drilling fluids around borehole walls creates considerable variations on mechanical and physical properties of both rock materials and discontinuities. However, up to date there is no comprehensive study has been performed on

Schmidt rebound values obtained by Schmidt hammer tests have recently been used to predict the uniaxial compressive strengths of both intact rocks and rough joint surfaces. The easy application procedure, short test duration and nondestructive nature

Certain drilling problems are frequently observed during different types of drilling (e.g. geothermal, oil, geotechnical). In order to maintain the stability of boreholes, analysis of the essential parameters affecting their stability, including indu

The shear strength of discontinuities has a prime importance in the assessment of structurally controlled stability problems. Natural discontinuity surfaces are usually not smooth and show irregularities, which have an important effect on their shear

Determination of P-wave velocity (V p), which is closely related to intact rock properties both in laboratory and in situ conditions, is a non-destructive, easy and less complicated procedure. Due to these advantages, there is an increasing trend to

This study aims to investigate the strength anisotropy associated with discontinuity orientation by performing block punch index (BPI) tests and uniaxial compressive strength (UCS) tests, and to develop some empirical relationships for estimating the
