In mining or civil engineering applications, blasting is an economical way to break rockmass. A production blast is planned to break only the rockmass required for removal, leaving the host rockmass with minimal damage. However, sometimes extra rockmass damage occurs due to improper explosive energy utilization, which is known as "Backbreak." It is crucial to control such rockmass damage in mining operations to ensure safety, minimize costs, and design efficient mines. This book presents two newly developed 3D nearfield vibration models for predicting rock damage in any direction in the 3D spa...
In mining or civil engineering applications, blasting is an economical way to break rockmass. A production blast is planned to break only the rockmass required for removal, leaving the host rockmass with minimal damage. However, sometimes extra rockmass damage occurs due to improper explosive energy utilization, which is known as "Backbreak." It is crucial to control such rockmass damage in mining operations to ensure safety, minimize costs, and design efficient mines. This book presents two newly developed 3D nearfield vibration models for predicting rock damage in any direction in the 3D space with improved accuracy. One model is for a single blasthole, while the other is for the simultaneous blasting of multiple holes. Additionally, the book provides an ANSYS FEM simulation for rock blasting to estimate the damage zone and subsurface analysis by geophysical survey method - MASW (Multi-Channel Analysis for Surface Waves).
