Vibration response of the waste rock dump in open pit mine ...

Vibration effect needs to be taken into account, especially when the waste dump is situated in close distance to the seismic loading source. In the open pit mine near Jarnoltowek (Poland), phyllite is excavated, and rock waste is deposited on the dump directly in the mine; that is at a distance of approximately 150 m from the quarry face.

Predicting Blast-Induced Ground Vibration in Open-Pit ...

To measure ground vibration induced by blasting operations in open-pit mine, peak particle velocity (PPV) is considered a standard criterion for evaluating the intensity of the ground vibration. More than 80% of the energy of explosives is released by generating ground vibrations that spread through the rock and soil to surrounding structures [ 2 , 3 ].
