Non-Cap Sensitive free flowing explosives based on ammonium nitrate and fuel oil
DANFO is a blasting agent and not sensitive to initiation by a detonator no 8, suitable for charging in the relatively dry blast holes of open pits and underground blasting.
While DANFO has a very low mechanical impact sensitivity. This impact insensitivity criterion is a very important safety feature.
If DANFO remnants are to be destroyed by burning, advice on the correct method should be sought from DAHANA Engineering Center or from the local explosives statutory authority.
DANFO is suitable for charging in the dry blast holes and will remain dry until initiation.
Designed to deliver high energy and used as a column charge in open pits and underground mining, quarrying and general blasting work where water is not present. DANFO is blasting agent and will deliver maximum energy and efficiency when initiated by a HDP booster.
The recommended priming methods for DANFO are either a cap sensitive Emulsion Explosives such as Dayagel Series or Nitroglycerine based explosives.
DANFO can be loaded in relatively dry drill holes using a pneumatic loader or poured directly from the bag.
RECOMMENDATION FOR USE
Dry Blast Hole
Danfo has very poor water resistance. Wet holes must be pumped out, blown dry. Another option is use Heavy ANFO with Dahana brand DABEX 55.
Heavy ANFO is comprising various blends of DABEX 100 and DANFO, used where water resistant or extra power charging is required.
DANFO has been designed as a non-cap sensitive explosives and will deliver maximum energy and efficiency when initiated by a high explosives solid booster.
The recommended priming methods for DANFO are either a cap- sensitive Emulsion Explosives such as Dayagel Series or Nitroglycerine based explosives.
DANFO can be loaded to blast holes using a pneumatic loader or poured directly from the bag
The DANFO packaging bag are colour highlighted in white and black label to clearly distinguish this product. Standard packaging are PE liner with woven PP outer bag and available in 25 kgs weight.
Storage and Handling
As with other hygroscopic explosives, the shelf life will be dependent on packaging condition. If the DANFO package is damaged, the shelf life is influenced by the extent of damage to the packaging and by the nature of atmospheric climate especially the humidity level.
Do not subject the product to impact and friction.
Store away from sources of heat or ignition and other chemical.
