Analysis of induced seismic background at Unal tailings pond by express-methods

The article describes the research data on the induced seismic background at Unal tailings pond from the developed express-methods. The current situation and the evolution of the body of Unal tailings pond within the latest decades are addressed in terms of the seismic risk assessment for the whole geosystem, and the induced seismic background estimates obtained using a network of seismic stations during their real-time field-operation are presented. Based on the accomplished research, the authors identify an essential correlation between the test nature-and-technology system and potential earthquake zones in the Sadon–Unal basin. The methodology of measurements aimed to improve information content of online-monitoring, as well as to compose and update the instrumental research data base meant for the identification of manmade and natural influence zones is described. The implemented investigation proves that the seismic monitoring of manmade objects, both in operation and after reclaiming, is an efficient control parameter for active geodynamic systems, and assists in planning and execution of appropriate activities to prevent or minimize hazardous geological processes connected with geodynamics. The research carried out using the proposed methodology, expressmethods and seismic stations DR-4040 and Delta-Geon 001 provided the real-time data for the subsequent assessment of the induced effect exerted by transportation flows on the body of the tailings pond, with the determination of the attenuation factor and the stress–strain behavior of the body of the tailings pond.
