The influence of the different rock type was investigated using regression analysis and the derived equations were statistically tested. Although the derived equation for all data is significant, the data points are scattered and the coefficient of correlation is not strong. However, when the regression analysis was repeated for igneous, metamorphic and sedimentary rocks respectively, the data were less scattered and stronger correlation coefficients were obtained.eninfo:eu-repo/semantics/closedAccessUniaxial compressive strengthPoint load indexRock classesArticle68334535310.1007/s10064-009-0195-02-s2.0-68249158247Q1WOS:000268294800007Q4
