Contamination By Particulated Material InBlasts: Analysis, Application And Adaptation OfThe Existent Calculation Formulas And Software

In the setting of a research project about the blasting negative effects granted with public funds coming from the Spanish Ministry for Development, several measurement campaigns were developed, in various locations and situations, where earth vibrations, aerial waves and dust in suspension simultaneously measured. Taking into account the dust negative effects (for human health, inhabited environment or plants) it is interesting to have available tools that allow the estimation of the particulated material quantities ejected in a blast (already studied by our research team in other cases). Here we show the application of the standardised computational methods for atmospheric contamination (developed for other applications) in the specific case of blasting in mining and civil works. To do so we have used the field data collected in blasts at a maritime port and at a limestone quarry. We will also show the advantages of using CFD when solving some of these problems, which is being studied in other research projects.
