“…Moreover, the common of regular astronomical-geodetic, satellite, seismic, geophysical, geological, and a number of other observations aimed at the simultaneous study and monitoring of geodynamic processes in the upper part of the earth's crust should be carried out on the problem area (group of deposits or ore provinces). It is advisable to organize regular system observations on a larger part of the SOF to obtain the missing information [14,18,19]. Besides the available technical means, additional ones will be required ( Fig.3): -A regional seismic network of 3 stations to be located along the perimeter of the SOF (included in the seismic register stations of the unified geophysical service of the RAS), the information obtained will allow to register and locate regional earthquakes; access to the seismic events database of region is necessary for interpreting the results obtained by other methods.…”

The principles of complexed geodynamic monitoring on the basis of long-term experience and research results of natural and man-made processes in the uranium deposits of the Streltsovsky ore province are proposed. The principles are to use simultaneously regular satellite, geodetical, seismical, geophysical, geological, and a number of other observations aimed at studying the upper part of the earth's crust. In the world’s mining practice, such large-scale integrated studies, where within the boundaries of one territory (a group of deposits or ore provinces) a similar set of observations aimed at monitoring geodynamic processes in the upper part of the earth's crust has not been found. The development of monitoring methods at the “Geodynamic polygon of the Streltsovsky ore field” and the additional placement of new multi-level monitoring systems will provide more information about the state of the rock mass in the upper part of the earth's crust, increase the reliability in prediction of dangerous geodynamic manifestations, identify their precursors and reduce the risk of man-made disasters. It is planned to create a common centre for processing and analysis of multiparameter data on geodynamic processes in the depth of the rock mass and local geomechanical processes near underground mine workings.

“…Equally oriented faults create the anisotropy of the medium, while microcracks form a network of small heterogeneities, determining the absorbing properties of the medium. The assessment of the geomechanical stability [1][2][3] and the safety of operation of various large-scale underground structures [4][5][6], such as tunnels and liquefied gas tanks, remains relevant [7,8], since the conclusions about the current geomechanical and geodynamic problems provided by mining research institutes state [9][10][11]that the tasks of ensuring safety and timely detection of critical situations that arise during the development of deposits and underground spaces remain not fully resolved. New methods and computer technologies make it possible to assess the stress-strain state in rock masses [12][13][14], but one of the widely used methods for such assessment is the acoustic emission (AE) method [15][16][17] , which studies the process of the initial stages of destruction (initiation and accumulation of microscopic cracks) [18] in various materials, such as rocks [19,20], building materials [21], composites [22].…”

To measure the energy of the source of acoustic pulses in the absolute scale of units (J) from the registered pulses, an analysis of the energy balance "source of pulses" -- "transmitting medium" -- "receiver of pulses" was carried out using a spectral analysis device. Comparison of two independent methods for determining the energy of elastic interaction (capacitive method and photoelasticity method) gave a discrepancy between the results of less than 12%. The spectral composition of the interaction energy is determined. The results make it possible to determine both the parameters of the signal source and the structure of the transmitting average signal conversion. To measure stresses in an elastic wave, a piezoelectric receiver, in which a piezofilm served as a sensitive element. This receiver differs from receivers made on the basis of piezoceramic elements, has a significantly lower non-linearity of the amplitude-frequency characteristic, since it has only two natural frequencies. Keywords: photoelasticity, elastic wave velocity, rock mass, concrete, acoustic emission.

The complexity of solving the problem of preventing natural and man-made disasters during intensive nature management is associated with the multifactorial nature of the conditions and causes of catastrophic events, significant variations in the properties and state of geospheres, and the lack of reliable criteria and precursors of dangerous dynamic phenomena. The modern scientific approach to solving this problem consists in modeling processes that allow to adequately describe the state of changing natural and technical systems with subsequent verification of the results of theoretical research by instrumental methods. An even greater effect is brought by the combined use of natural and theoretical methods, united by a common ideology and maximally adapted to the conditions of the problem being solved, providing continuous multivariate monitoring of geophysical fields and processes in the geospheres. In this regard, it seems very urgent to set up research work aimed at the development of scientific and methodological foundations and technical means for assessing and monitoring hazardous geomechanical processes to reduce the risk of man-made disasters during the development of mineral deposits.
