Abstract

Noise and airblast are unavoidable by-products of blasting in mines and quarries, affecting all components of the environment. A mining project must recognize the vigorous adverse impacts due to noise and airblast emissions while planning and executing the different stages of the extraction of mineral. The construction and operational stages of the project should be designed and managed to best minimize these adverse impacts. The extent of these adverse impacts should be quantified during the execution phase of the project. Based on the predictions of the levels of noise and air overpressure at potentially sensitive locations, the project work should be modified to mitigate the impacts to within acceptable limits. In this paper, the air overpressure data of three different coal mines in India have been analyzed to form a generalized predictor equation. The level of air overpressure can be predicted by the equation, which can provide a guideline to the mine owners to modify their mining activities in order to minimize the adverse impact of noise and air blast.
