Assessment of Blasting-Induced Ground Vibration in an

In an open-pit mine slope, rock mass has multiple joint structures and blasting operations have an obvious influence on its stability. Therefore, accurately predicting the blasting vibration is necessary to ensure slope stability. In this study, the blasting vibration signals monitored at a blasting site with different rock masses were used to investigate the attenuation characteristics of

Shock and Vibration Hindawi

Ground vibrations originating from bench blasting may cause damage to slopes, structures, and underground workings in close proximity to an operating open-pit mine. It is important to monitor and predict ground vibration levels induced by blasting and to take measures to reduce their hazardous effects. The aims of this stone are to determine the weaker protection objects by comparatively

Blast vibration effects in an underground mine caused by

Blast designs for open-pit mine were optimised which resulted into lower level of vibration in the underground openings. The monitoring of vibration in the sidewalls is more feasible for each blast and accordingly the predicted maximum explosives weight per delay in open-pit blast as well as underground blasts has been standardised so that vibration experienced by the underground openings must
