Abstract

The stress fields around a noncharged borehole (NCB) due to blasting stress waves were researched by dynamic photoelasticity and gauges. The action of stress concentration and reflection by a NCB were analysed according to the dynamic recorded results. The guiding mechanism of a NCB was further explored.
