Study on Influence of Air Decouple Charge Impact on Blasting Stress Field in Rock

摘要

According to the theory of detonation and stress wave, initial shock pressure in wall of air-decoupled charge was deduced in theoretical and blasting stress field of air-decoupled charge in rock was established. Influence of decoupled coefficient to blasting stress field was analyses combined with test result, the result further proved decoupled charge can reduce compression stress obviously, the greater coefficient and stress reduce the more notable.
