Реферат | Over the time of buildup and development, Apatit JSC has been drawing reserves from the apatite-nepheline ore deposits of the Khibiny Mountains: Apatite Circus, Rasvumchorr Plateau, Kukisvumchorr and Yukspor deposits. The long-term mining impact and the vast areas undermined, including faulting zones, condition the instability of the Khibiny Mountains area. The article describes the research of the relationship between the seismicity in the area of the long-term opencast and underground mining of the Khibiny apatite-nepheline ore and the seasonal watercut and water saturation of undermined rocks and mine goafs. Based on the research findings, criteria are set for water influxes that come before hazardous induced seismicity, and the procedure and the technology-and-equipment complex are developed on this basis for forecasting seismic activity dynamics depending on weather and ground water hydrology. The authors give real-life examples of the seismicity forecasting using the algorithm and the computer-aided programming Seasonal Seismic Identification System (AS SSAIS) Thus, for the conditions of Apatit JSC ore bodies and mines, the modern technology-and-equipment complex has been designed and adopted for forecasting seismic activity dynamics based on the joint analysis of the seismicity and weather and hydro-monitoring, with the assessment of natural impact on the induced seismicity. |
