“…As a result, the rock surface evaporates by the departure of positively charged ions and electrons. The improvement and application of fundamental and field studies of shock wave parameters for the analytical assessment of geomechanical stability and operational safety of various large-scale underground structures, such as hazardous waste storage facilities, tunnels and liquefied gas tanks, remains relevant [1][2][3][4][5]. The main research method is the analysis of acoustic emission pulses (AE), which is widely used to study the process of predestruction (nucleation and accumulation of microscopic cracks) in heterogeneous materials, such as rocks [6][7][8][9][10].…”

The spectra of the plasma emitted from the studied samples consist of several dozens of narrow bands superimposed on each other. Tables of spectral lines were used to interpret the spectra. It turned out that the largest number of bands corresponds to the radiation of positively charged ions and atoms of elements that make up the crystal lattices of minerals that make up the studied rocks. Thus, the spectra of the plasma emitted from quartz corresponded to the radiation of atoms and positively charged silicon ions, the charge of which varied from 1 to 4, as well as atoms and positively charged oxygen ions, the charge of which varied from 1 to 3. Positively charged ions and atoms of Si, O, K, Ca, Al and Na, which are part of the crystal lattices of quartz and feldspar, flew out of granites. Positively charged ions and Ca, C and O atoms flew out of the calcite.

“…On this basis, in the environment of MINEFRAME mining geology information system (MGIS) [9,10], a bundled suite of software tools has been developed to encompass geological and geotechnical conditions, as well as engineering constraints and processing limits. The software tools are developed for operating conditions of PIMCU [11] and Yakovlevsky GOK [12]. The specificity of these underground mining practices is the use of the downward horizontal-slice dry-fill method.…”
