| Summary: | Relevance of the research is caused by the need to highlight the geological hazards in planning the industrial facilities (gold beneficiation plant and tailings dam) of the deposit «Nezhdaninskoe». The aim of the research is to carry out a complex of geophysical explorations for assessing the physical condition of the medium under study and to predict potentially dangerous areas to detect geological hazards. Research methods: registration methods of microseisms and seismic impedance for seismic microzoning of area. Seismic hazard degree is calculated using instrumental and computational methods, a full set of features is received as required for planning the constructions. The dislocations with a break in continuity were determined using axial dipole sounding method and correlation refraction seismic. Via these methods the dislocations with a break in continuity were highlighted: wave propagation velocity tends to zero in the assumed zone of dislocations with a break in continuity and resistivity contours correlation is broken. The buried ices masses were determined using axial dipole sounding and self-potential methods and filtering zones - by self-potential method and axial dipole sounding. Filtering zones and buried ice masses were singled out; the buried ices effect on natural field parameters is noted: within the buried ice propagation intervals the values of natural field potential difference tend to a minimum. Conclusion. The authors have plotted the map of potential geological hazards and proposed the alternative types of tailings storage. The studies shown the impossibility of tailings impoundment construction taking into account the complex engineering and geologic region, geological hazards, high hydrodynamic risk, costly affairs for construction, fit-out and maintenance. As an alternative tailings are proposed to store: in «dry state» at the testing ground without organization of tailings dam or in thickened «pasty state» preserving frozen state of the main mass of wastes and soils. |
