converting k factor from PL into UCS being (2224) x 𝐼 (50) and a whole range of other conversion factors for UCS and BTS. However, over the past years, throughout the whole previous researches all these factors were found to changing based on rock types and other geological properties in the rocks.

Halfcore and core samples were compressed up to failure during the Point Load Test (PLT) and Uniaxial Compressive Strength Test (UCST), respectively, and the PLT index (PLTI) and compressive strength were calculated. A conversion factor between PLTI and UCS .

strength (UCS). Broch and Franklin [17] suggested a conversion factor of 24 as a correlation between UCS and I S(50). However, this conversion factor is more effective for hard rock materials than soft rock materials. The strength of soft rock materials is much lower than that of hard rock materials, so the conversion factor

In studies of Geotechnics, PLI (Point Load Index) and Uniaxial Compressive Strength (UCS) test are used to determine the value of the rock strength. PLI tool and test procedure allows the test can be done more economically than the test of UCS. The conversion factor ( K ) can be used to estimate the value of UCS based on PLI value.

It has been observed by the authors that there is a very wide range in both the Is50 and UCS results for the Calp Limestone and that UCS values predicted from Is50 using a conversion factor of 21 to 24 can vary widely from actual UCS results from nearby samples.

The strength conversion factor (k) is the ratio between the uniaxial compressive strength (UCS) and the point load index (PLI). It has been used to estimate the UCS from the PLI since the 1960s.

Conversion factor (CF) Different conversion factors apply to rocks of different strength [34]. The conversion factor between UCS and PLTI (Factor 1 and Factor 2) was determined for oil shale and dolostone layers by using different methods. The anisotropy of resistance of oil shale and dolostone to disjointing was also determined (Factor 3).

You won't usually find a conversion from kilograms to grams the prefix 'kilo' means '1,000' so a kilogram is in fact 1,000 grams in the same way as a kilometer is 1,000 metres [or about 1,000 yards in 'old ...

The uniaxial compressive strength (UCS) of intact rocks, as estimated from the point load index using conversion factors, together with the Hoek – Brown constant mi, and the Geological Strength Index (GSI) constitute the parameters for the calculation of the strength and deformability of rock masses.

Abstract Nine rock types including Sandstone, Limestone, Siltstone, Dolomite and Marl collected from six different rock formations of the Salt Range area of Pakistan were tested to evaluate the correlations between the uniaxial compressive strength and the corresponding values of the point load index.

The limestone core samples simultaneously drilled from side wall have an average conversion factor from PLS to UCS of The mean conversion factor from PLS of blocky fragments to UCS of limestone in the present study is

Jan 30, 2014· The conversation factor for sedimentary rocks is in the range between 16 and 24 [28–31, 34, 35]. The following linear regression model is used to correlate UCS and IS(50): UCS = (16 – 24) Is(50), (2) where UCS is the uniaxial compressive strength, MPa, .

Nov 11, 2011· Uniaxial compressive strength (UCS) is one of the most significant geomechanical properties of rock, being of importance in civil engineering, mining, geotechnical, and infrastructure projects, etc. ... Point load index (PLI) Conversion factor Conversion coefficient ...

A correlation factor (k) between uniaxial compression strength and point load test of about (6) has been proposed, for rock of very low strength of MPa or less. This study confirms that the UCS estimation equations are rock dependent. But as the ratio of (mean UCS/mean PLT) increases the k factor increased linearly as the equation,

UCS/mean PLT. INTRODUCTION . The Point Load Test (PLT) was developed as an index test to predict the Uniaxial Compressive Strength (UCS) of core too broken for UCS testing. A correlation factor (K) between UCS and PLT strength of 24 has been proposed although this value is disputed. This paper investigates the value of K for some Iraqi rocks using
