DABEX and ANFO Blend are waterproof Bulk Explosives specially designed for application in wet blasting conditions in open pit mining applications. They have been designed to be pump able using bulk delivery truck through a flexible loading hose lowered to the bottom of the blast hole. This product has been formulated to be used in holes down to 35 mm diameter, dependent on emulsion content and hole depth.


DABEX can be used by itself or in blends of up to 60% by weight of ANFO. Gassing of the DABEX emulsion phase provides controlled modification of final blended product densities, detonation pressure, bulk explosives strength and gas volume.
The ability to gas the product allows the density of DABEX/ANFO Blends to be varied across the shot as ground conditions dictate. Blasting costs are also kept to a minimum as bulk explosive loading strengths are optimized.

Priming Requirements

All DABEX/ANFO Blends are formulated to be non-detonator sensitive products and require a minimum 400 gr TNT/PETN cast primer.
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.

Sleeping Time

DABEX and ANFO Blends will sleep in dry holes for up to three months.

The product will sleep in wet holes for up to 30 days provided there is relatively little dynamic water flow through the geological strata.
Since product performance is dependent on factors such as, but not limited to, hole diameter, priming conditions, ground water and product density, DAHANA personnel should be consulted if unusual conditions exist.

First Aid

DABEX and ANFO Blends are considered to be practically non-harmful, unless absorbed in large amounts.


Explosives are dangerous and can cause personal injury and damage to property if used incorrectly.
All explosives must be handled, stored and used in accordance with explosives regulations.
