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.
Environmental impact of explosion on the environment is associated with a significant release of harmful gases and dust into the atmosphere, their pollution and products of incomplete decomposition of explosives of the ground and groundwater. In places of mass blasting works during mining of minerals there is chemical pollution of ground and surface water, deterioration of the biological landscape. In large-scale explosions may fall solid precipitation and acid rain at large distances from the explosion site.
The phenomenon of detonation underlies numerous technologies for the beneficial use of explosive explosive energy (EE). The history of its discovery and study goes back more than a hundred years, but many aspects remain unclear.
