DHDA™ is a pressure wave reflecting polymer that redirects the shockwave explosive power in the initial blast directly into the hard wall surface to dramatically increase fracturing to reduce rock size. By using DHDA™ numerous performance benefits are realised: reduction in time loading in wet holes; ensures ANFO option is available; reduces blasting noise and dust; reduces oversize equating to substantial down stream savings.
Why use DHDA™?
Easy to pour down blast holes
Rapidly drys and solidifies invasive down hole water
ANFO can be used instead of emulsions
Increased P-WAVE performance upon detonation
Reduces multiple operational costs
Easy pour granulate into blast holes
Simplifies bench loading procedures
Rapid solidification of water
Effective across varied water qualities
Protects ANFO from dynamic ground water
Can be used with all explosive types
Creates P-WAVE reflecting deck
Improves blasting results
Saves time and reduces costs
Non hazardous and non dangerous
Typical Dose Rate
100 grams per litre of normal ground water. Increased dosage is required for high TDS water. Product applied at 50 grams per second.
Use Anfo - Not emulsion
