Abstract : Quarry mining practices vary considerably within the United States and worldwide, the variations reflecting the materials that are to mined, the means for removing and processing the materials, operator preferences, safety considerations and constraints imposed by nearby population and structures. Models of quarry blasts that can be used to develop efficient and robust methods for discriminating quarry blasts from other source must reflect the varied practices. Development of models for quarry blasts was the subject of work done at S-CUBED under a previous contract to ARPA. Under a new contract to DoE (which has not been initiated), we will validate and extend the models using using near-source and regional data. Our objective will be to use the models to determine the sensitivity of proposed regional discriminants to varied mining practices.
