Analysing the Cause of Miss-fire of Detonate-tube Priming Circuit

摘要

Comprehensive analysis of die cause of miss-fire of detonate-tube circuit indicates that quality of detonate and detonate-tube, laying and connect mode of net, harm of blasting air-impulse wave and blasting slungshot, complicated geological formation and operation technology and so on are the main causes of miss-fire. At the same time, a series of corresponding measures for against miss-fire are put forward, and draw proper treating methods of miss-fire according to interrelated rules of Safety Regulations of Blasting.
