What is Assessing and Controlling of Bench Blast about?
This document summarizes a study that assesses and controls ground vibrations from bench blasting at a large open-pit iron ore mine near a community in Brazil. The study involved measuring 178 levels of blasting-induced vibrations in the area. Regression analysis was used to develop an attenuation law to predict vibration levels based on explosive charge and distance from the blast. Brazilian and international standards were used to establish acceptable vibration levels and set limits on explosive charge to
