On the Assessment of the Criticality of Rocky Banks Dynamic Loading during Mass Shooting in the Open-Pit Conditions
On the bases of the seismic observations analysis for mass explosions it is established that the maximum vector displacement velocity value registered during seismic measurement cannot be served as the index of the criticality of the rocky banks dynamic loading because its criticality level depends on the duration of the block explosion. To assess the level of the rocky banks weakening it is required to use the value of the volumetric energy saturation, and the critical value of this parameter - to define considering adopted safety margin of the stability of banks placed at the end position
