Increasing Geodynamic Safety by Managing Induced Seismicity During the Development of Solid Mineral Deposits


Annotation:

The urgency of the problem is determined by the fact that in conditions of intensive mining and other technogenic factors, an induced component arises that has a significant impact on the overall seismicity of the region. 
The scientific analysis of the published works, both domestic and foreign, shows that the issues related to the occurrence of induced seismicity in the development of mineral deposits (including solid ones) are actively discussed, many studies are devoted to the causes of its occurrence, but there is no information in the open press about research in the field of induced seismicity management. 
Patent analysis also shows the absence of technical solutions related to the management of induced seismicity in the development of solid mineral deposits.
The novelty of the method of controlling induced seismicity in the development of solid mineral deposits using drilling and blasting technologies lies in the fact that seismic events are recorded in the corresponding territory and their main characteristics are determined. Moreover, at the first stage, seismically active areas of the territory are identified, at the second stage, the total released seismic energy of seismic events in the contoured areas of the territory is determined, and at the third stage, the actual values of the density of the released seismic energy are compared with its threshold value for each contoured area of the territory. Depending on the result of the comparison, control information is not formed or formed, and the latter is presented in the form of recommendations for reducing the frequency and power of explosions, the number of explosive deposits, reducing the deceleration of explosions during the extraction of solid mineral deposits, as well as the volume of charges laid at the same time.
The eastern part of the Orenburg Region, which is characterized by a large number of solid mineral deposits, was selected for implementation. These deposits are being actively developed by the mining campaigns.
