The paper presents results of experimental study of microstructural changes in rock specimens under the effect of high pulse pressure due to shock waves. Specimens of strong rock and coal were placed into special steel preservation ampoules. Shock waves were generated by explosion of trotyl blocks. The study involved electron microscopy, micro- and nanoindentation and laser spectroscopy of particle size. Images of specimen surface fragments were obtained by electron microscopy at various scale levels before and af...
