AB  - In recent years, the mining industry has dealt with a significant amount of criticism regarding the side effects of production blasting. In practice, explosive material is placed into a series of boreholes in a rock mass, and then detonated to fragment the rock so that it can be disposed or transported for further processing. The detonation of an explosive charge is a rapid and high-energy reaction which imparts shock waves into the surrounding rock mass; however, not all energy is consumed in the fragmentation process. One of the most significant side effects of explosive blasting is the generated ground vibrations, which can travel a great distance from the site. With mining sites being located closer to urban areas due to urban growth, these generated ground vibrations can easily pose a problem for residents in the form of discomfort or structural damage. The focus of this paper is on the initial development of a numerical model to characterise the propagation of vibrations in these areas with two distinct aspects. The first part is focused on modelling the vibratory source. Since detonation and rock fragmentation are highly complex phenomena, the equivalent cavity theory is applied in order to maintain a single elastic ground model. The second part deals with the development of a ground model to simulate wave propagation and estimate the level of vibrations produced. The goal of this research is to develop numerical models which can be used by mining operators to predict the ground vibrations generated depending on factors such as the blast design, site configuration and geological parameters.
