Vibration Effects on Underground Concrete Structures

In open pit blasting, energy is released and transmitted through the geology. Negative effects can impact operations and can affect mine production. This paper presents recommendations for blast design to prevent damage due to ground motion from blasting on adjacent concrete structures of underground operations. It includes a case study describing a problem regarding an open pit mine expansion and asks whether production blasting will damage concrete shaft structures due to blast stress waves and blast-induced ground motion.
