Abstract

Disturbed zones of rock have been measured for blasted highway rock cuttings by the Transport and Road Research Laboratory (TRRL) of Great Britain. These zones vary in depth depending on blasting technique. The depth of disturbed wall rock due to excavation by various explosive techniques including fracture control, pre-splitting, smoothwalling and bulk blasting was investigated for underground excavations utilizing small diameter (1. 5-1. 75in. ) blast holes. The fracture control technique was the most effective method of minimising blast damage.
