Abstract
Rock breakage by chemical explosive is a complex process involving the physicalproperties of the rock mass, the detonation properties of the explosive and blastparameters. A method for model scale blasting in cement mortar blocks with dimensions 90 x80 x55 cm has been studied and the results from a single shot experiment instrumentedwith accelerometers, strain gages and pressure gages are given. Results from staticand dynamic materials testing of the cement mortar are also given. The stress time and strain time determined by the different methods are compared.
