Abstract

Abstract

Using water, air and rock powder as interval materval materials, the explosive experiment of interval charge is made. Interval effect on broken block degree is researched. The difference of interval charge of three materials and coincidental charge is discussed. Influence of position, length and materials on rock broken effect are analysed.
- blasting,
- explosive charges,
- breaking/limited interval,
