Abstract
Estimation of stability of natural slopes, embankments, dams and open-pit slopes during earthquakes are complex and non-linear problems, therefore physical modeling is used for decision of it. As a result of physical modeling the pattern of seismic vibrations impact based on the movement process of probable collapse prism delineated by the most stressed plane of sliding has been established. Particular recommendations on the basis of safety factors selection in seismoactive zones are given.
Highlights
At present, the explored reserves of a whole number of mineral resources are being exhausted at the readily accessible shallow deposits in safe seismic regions in Russia
At many mining regions with enormous amounts of excavated materials (e.g. Kuzbass, the Kola Peninsular, many zones of the Urals) one can observe the growth of technogeneous seismicity, that leads to enhance the influence of seismic waves on open-pit slope stability
Most of them are positioned at Kuzbass within the zones of vibration level VI-VII, but, as exploring for mineral resources in Siberia and the Far East, it is expected the rise of number of opencasts being located within the zones of the intensity VIII and even IX of seismic vibrations
Summary
The explored reserves of a whole number of mineral resources are being exhausted at the readily accessible shallow deposits in safe seismic regions in Russia. The most widespread method of seismic impact accounting on stability of open pit edges and open pit slopes is pseudo static approach [2,3,4,5,6,7,8,9,10]. Application of it leads to sufficient strong overstating of safety factor and ignores existing information about influence of relative small but longstanding oscillations from far earthquakes on the slopes stability, for instance [11]
