Features and Benefits Recommendations (continued)
▪ Charge concentrations are reduced due to the lateral decoupling of the Using the ANFO hose, push the Z-BAR charge fully to the toe of the blasthole. cartridge, resulting in smooth and consistent perimeter results. The Z-BAR tube charge must be contained fully within the blasthole, with a gap
 left to the collar of the blasthole. This will minimise failures due to “suck out”. ▪ Clean floor splitting is achieved by the high velocity of detonation of the
 internally traced 10g cord. Ground Temperature - Suitable for use in ground with a temperature range from
 0°C to 55°C. ▪ A continuous ridged tube with Z-shape concertinas are pre-cut to standard drill
 lengths, reducing deployment and charge time. Shelf life - Z-BAR products have a recommended shelf life of 12 months when
 transported and stored under ideal conditions. ▪ The continuous plastic tubes are water resistant allowing charging into dry,
 through to fully wet holes. Safe handling, transportation and storage
