Abstract

A methodology has been developed and experimental studies have been carried out to evaluate structural changes in rock samples in the near zone of explosion action. Using optical microscopy and X-ray structure analysis, it was found that the microstructure of rocks changes during the passage of shock waves: the dispersion of mineral grains increases, and the density of micro-disturbances increases by an order of magnitude.
