- Аннотация: New modifications of the optical scanning technique provide non-contact measurements of rock thermal conductivity and volumetric heat capacity on full-size core samples, core plugs, broken cores and other types of rock samples. Data on formation heterogeneity and anisotropy and rock structure and texture can be obtained from continuous non-contact thermal core logging developed that allows to characterize heterogeneity and structural-textural peculiarities of rocks with a spatial resolution of 0.2-1 mm. Principal axes of thermal anisotropy can be established from several non-parallel optical scannings.Thermal scanning presents information for a reasonable selection of rock samples for following measurements of geomechanical characteristics. The implementation of the technique opens wide possibilities in rock mechanics and rock engineering, because continuously measured thermal properties, and data on heterogeneity and anisotropy reflect variations in rock fabric and composition that also drive the variability of geomechanical properties. Observed correlations between the rock thermal and geomechanical properties confirm that. © 2016 Taylor & Francis Group, London
