Abstract

The inevitable and undesirable outcome of the blasting process is ground vibration. Numerous empirical methods and formulas, for the impact of travel pathways, have been examined and produced. Among these, when both explosive charge and distance vary, the scaled distance technique for the prediction of particle velocity on the ground has shown notable advancements. These correlations, however, are unable to identify the significance of variations in the characteristics of the rock and the uncertainty of the in-situ conditions. This is evident that the ground anisotropy and the presence of structural geological characteristics from various strata affect blast induced ground vibrations and associated frequencies. This study is an attempt to explore various rock mass characteristics affected the frequencies and amplitudes of ground vibration waves at six distinct locations having different six rock types. The investigation was done for the wave natures of many rock types, including basalt, Iron Ore, limestone, schist, sandstone, and bauxite. The main findings come from examining how the amplitudes and frequency characteristics of blast waves vary based on the transmitting rock or ore and surface where sensors were placed. It was also discovered that there are notable differences in the rock types in terms of vibration amplitudes and persistence when measured at identical distances from the source. The in-situ structural features were also responsible for the vibration anomalies, in addition to the variation in wave type caused by the various types of rock. The signature (single) hole analysis and interval analysis was performed for all the six rock types to mitigate the ground vibration and frequency problems associated with blasting.
