Experimental and theoretical framework of nonlinear tomography. Part III: Promising systems to control deformation and wave processes in surface and underground mining

To expand the range of instrumentation for nonlinear geotomography using pendulum waves, recording of complex deformation and wave processes, as well as analysis of the related seismic emission processes induced by surface and underground mining, earthquakes and powerful explosions, this article describes the modern and promising measuring equipment designed by the Institute of Mining, Siberian Branch, Russian Academy of Sciences. Specifications of the equipment provide recording of the dynamic and kinematic characteristics of pendulum waves in high-stress geomedia with hierarchical block structure. The formalized connection between such structure and seismic emission processes was described earlier (Part II of the article). This part of the article presents two basic measuring and computing systems for monitoring absolute displacements and strains in real geomedia in a dynamic mode in underground and surface mines under extreme climate of Siberia. Efficiency of the measurement systems in recording of low-velocity (less than 100 m/s) pendulum waves is illustrated by the field records of blasting at copper–nickel mines in the Norilsk Region (instrumentation system MOED-p) and in open pit mines at the kimberlite pipes in Yakutia (multi-functional deformation–wave measuring and computing system Karier). The comparative analysis of these records and the wave packets of higher gas-dynamic activity induced in Kuzbass mines by earthquakes according to the readings of automated gas control systems shows the deterministic connection of earthquakes and low-velocity pendulum waves (less than 5 m/s).

Keywords: Geotomography using pendulum waves, high-stress rock masses, hierarchical block structure, nonlinear deformation–wave processes, measuring and computing equipment for pendulum wave recording, underground mines of Norilsk, kimberlite pipes and open pit mines of Yakutia, field records of production explosions, gas control system, earthquake-induced gas-dynamic activity in Kuzbass mines.
