Exactly 206 individual test results, from 35 distinct rock units were used. The average values for UCS and PLI are taken for a rock unit since one unit is used to core around more than two samples, for each test. The conversion factor between UCS and PLI of the study is found to be between 9 and 14.

The Influence of Pre-Existing Deformation and Alteration ...

For example, the PLT to UCS conversion factor can vary from as low as 8 to as high as 30, while the ITS to UCS conversion factor values vary between 2.7 and 50 [43,44]. This implies that the conversion factor is a rock characteristic parameter and not a universal value; therefore, its applicability must be assessed on a case by case basis.

Point Load Test of Half-Cylinder Core Using the Numerical ...

The point load test (PLT) is intended as an index test for rock strength classification or estimations of other strength parameters because it is economical and simple to conduct in the laboratory and in field tests. In the literature, calculation procedures for cylinder cores, blocks, or irregular lumps can be found, but no study has researched such procedures for half-cylinder cores.

Because PLT and ITS are easier and quicker to perform compared to the UCS, many authors have tried to relate the PLT and ITS to UCS [21–23]. Experiments performed on a large variety of intact rock types have shown that indeed tensile strength can be correlated to the UCS by a conversion factor, k [22–24]. However, conversion factor k is non ...

In agreement with previous observations on weak rocks (Palchik and Hatzor, 2004; Kahraman et al., 2005, Sabatakakis et al., 2008), the linear correlation factor between PLT and UCS tests has a value approximately half of the standard value (UCS/I S50 = 24.5), which is proposed as a good approximation for all the rock types by ASTM D5731-07 (2007).

NEW DEVELOPMENTS WITH THE COAL MINE ROOF RATING

The axial PLT is used to measure the UCS. The Point Load Index (Is50) is converted to UCS by the following equation: UCS = K (Is50) 1 ) (Where K is the Conversion Factor. Mark and Molinda (6) originally adopted the K values proposed by Vallejo (7) for the CMRR, which were K=12.5 for clay-rich rocks, and K=17.4 for silty and sandy rocks.

Jun 27, 2013· From the literature, it is evident that for different rock types with specific geology, different conversion factors are to be used to predict UCS from Is (50). The Schmidt rebound hardness test is a semi non-destructive method which is used as an index test to estimate UCS.

formula for the calculation of the UCS based on corrected Is to a specimen diameter of 50 mm Is(50). The index-to-strength conversion factor (k) relating UCS to Is(50) was reported to depend on the compressive to tensile strength ratio, the Poisson's ratio, the length and the diameter of the rock specimen. Their theoretical prediction for k=14.9

Sep 01, 2015· Two different methods were used to determine the conversion factor between UCS and PLTI. One method was employed to determine the conversion factor for each sample separately. For example, for finding the value from PLTI normal to UCS for oil shale, the conversion factor was 14.0 [+ or -] 5.4 with a probability of 95% (Table 1).
