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
Rainstorm | Dust Control Products and Soil Stabilisation
Rainstorm is a specialist dust control company which offers a suite of products and specialist services to Mines, Civil Contractors and Local Governments. Since its inception in Australia in the early 90’s Rainstorm have been focussed on the dust control, soil stabilisation and rehabilitation industries. As the company has grown over time additional solutions have been developed by Rainstorm pertaining to dust management. These include automated rail car veneering, ore conditioning products along with dry fogging systems for crushers and ship-loaders. With the development of our own in-house engineering and construction capabilities Rainstorm is now creating site-specific application units, including full automation and installation along with the attendant contractor services.
With experienced corporate staff and an industry-skilled team of operators, Rainstorm is committed to its clients’ developing projects from initial site meetings, project scoping, product development and operations delivery through to corporate reporting, commissioning and maintenance stages.
