Research on Effects of Blast Casting Vibration and Vibration .

Jun 29, 2016 . Blasting operation, the initial step in open-pit mining, may break the ores into fragments so that they can be mined and loaded by excavating equipment. However, this operation might create environmental impacts such as air overpressure, ground vibration, fly-rocks, and back-break around the blasting.

vibration in open pit mining,Vibration response of the waste rock dump in open pit mine caused .

Analysis of slope stability is often solved when designing and realizing waste dumps. 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.
