function

Expanfo is an innovative ANFO (Ammonium Nitrate Fuel Oil) product where, in addition to natural porosity, sensitising plasticmicrospheres are included in-situ into each Ammonium Nitrate Prill.

Note:The microballoons remain intact and entrained in the ANFO (Ammonium Nitrate Fuel Oil) during pneumatic loading, thereby enhancingdetonation sensitivity in the blast hole. This results in a more ideal detonation behaviour and superior field performance compared to thatachieved with equal volumes of standard market ANFO products.

descriptionExpanfo gives superior hanging-wall control and generally more consistent and predictable blast results, especially in tough blastingconditions or when the product is initiated without a primer. Expanfo is available in 2 grades varying in product strength and detonationcharacteristics to provide the customer with a choice for achieving the highest value solution for the specific application.

advantagessafety Expanfo, due to its low sensitivity to shock, friction or impact, is comparatively safe to handle.

Misfires are easily treated by washing the charge hole with water, rendering the Expanfo insensitive.

reliability Anti-caking agents make Expanfo free-flowing for improved performance in underground or surface

applications. Expanfo will reliably initiate with a 6D+ detonator when loaded pneumatically.quality Manufacturing of this product conforms to the ISO9002 quality standard. Tests are conducted to

confirm that the density, prill size, moisture content, anti-caking properties and fuel content conformto specifications.

product information

expanfoTM200

A medium density of Expanfo 200, (when compared to standard ANFO) is a general purpose ANFO product for hard rock stopingapplications, bord & pillar and easier development conditions. Expanfo 200 is ideal to limit over-break or excessive fines.

expanfoTM300Expanfo 300 is a higher density ANFO product for tough development conditions or any applications where higher energy is required.

* The mass per bag differs depending on Expanfo grade. However the volume per bag (and thus quantity blast) will remain thesame.

** Energies calculated using the Tiger code ( JCZ3). (Should not be compared with energies evaluated using other methods).

important instructions

Always store detonators and explosives separately.

Keep ANFO away from sparks , flames or any other source of ignition.

Store explosives and accessories according to country rules & regulations.

ANFO is soluble in water and can therefore not be used in wet conditions.

Energy** VThe theoretical energy for ideal detonation is essentially the same for all ANFO

products (RWS = 1). However, actual detonation performance of ANFO products

deviates signicantly from this ideal. Expanfo products detonate closer to the

ideal due to the inclusion of the sensitising microballoons. The in-hole density

decreases from Expanfo300 to Expanfo100.
