THE IMPORTANCE OF THE REFLECTED STRESS WAVE IN ROCK BLASTING

THE FRACTURE PATTERNS IN PERSPEX MODELS, SIMULATING ROCKBLASTING SITUATIONS, WERE USED TO ASSESS THE ROLE THAT REFLECTED STRESS WAVES PLAY IN DETERMINING THE DEVELOPMENT OF FRACTURING AROUND BORE HOLES. THE RESULTS SHOW THAT THE REFLECTED WAVES ARE EXTREMELY IMPORTANT. THE REFLECTED STRESS WAVE FROM THE NEAREST FREE SURFACE, WHICH IS THE STRONGEST, DETERMINES THE DIRECTION OF THE FRACTURES THAT CONTROL THE MAIN BREAKOUT ANGLE.
