Abstract

Geophysical methods of investigating rocks are used to define the geological structure of mineral resources by borehole sections, identify and evaluate iron ore raw materials. Geophysical data can be also applied to designing, controlling and analyzing deposit mining and engineering states of mine workings. The research is aimed at improving accuracy of ultrasonic logging to determine physical-mechanical and chemical-mineralogical characteristics of rocks based on the fuzzy clustering of the results of ultrasonic measurements: velocity of longitudinal and transverse wave propagation, the ultrasonic attenuation coefficient at fundamental frequency and higher harmonics and relationship of these parameters.
