DANFO (Dahana Ammonium Nitrate Fuel Oil) is a non cap sensitive free flowing explosives based on Ammonium Nitrate and
Fuel Oil, manufacture by PT Dahana. This type of explosive is commonly known as ANFO, suitable for relative dry blast holes of
open pits and underground blasting. DANFO is used as an industrial explosives and ensure safety, ease of handling and much
more economic to use than any of conventional explosives.
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 High Detonation Pressure 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 in relatively dry drill holes using a pneumatic loader or poured directly
from the bag.
All DABEX/ANFO Blends are formulated to be non-detonator sensive products and require a minimum 400 gr TNT/PETN
castprimer. Two primers per hole are recomended for deep holes or where the charge colums may have been disrupted.
Detonating cord downlines are not recommended
If detonating cord is used, double priming at the top and bottom of the explosive column should be employed for column lengths
greater that 5 metres.
