Literature review information and model scale rock blasting tests have been utilized to study the effects of some blast and fragmentation parameters on peak p-wave stress. A method for modeling scale blasting in sandstone blocks with dimensions of 515×335×215 mm3 has been studied and the results from a blast experiment instrumented with a pressure gauge are given. The dynamic and static properties of the sandstone are also given. The instrumented tests in such blocks using pressure gauges and the effects of blast and fragmentation parameters on peak p-wave stress are studied.
