Abstract

A study has been undertaken to establish relationships between the O&K wedge test cutting resistances, F(A), F(L) and F(LS), and the geotechnical parameters of rock materials in the context of bucket-wheel excavator operation. Prediction equations were formed to estimate the cutting resistance from the geotechnical parameters by multiple regression analysis and the cone indenter index, uniaxial compressive strength and Shore hardness parameters have been found to be the most significant predictors.
