ExpanfoTM

packaged anfo explosives

function

Expanfo™ is an innovative ANFO (Ammonium Nitrate Fuel Oil) product where, in addition to natural porosity, sensitising plastic microspheres 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 enhancing detonation sensitivity in the blast hole. This results in a more ideal detonation behaviour and superior fi eld performance compared to that achieved with equal volumes of standard market ANFO products.

description Expanfo™ gives superior hanging-wall control and generally more consistent and predictable blast results, especially in tough blasting conditions or when the product is initiated without a primer. Expanfo™ is available in 2 grades varying in product strength and detonation characteristics 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 conform to specifications.

custom packaging ExpanfoTM is packaged in a colour poly-cloth or polyethylene bag.

product information

expanfoTM200A medium density of Expanfo™ 200, (when compared to standard ANFO) is a general purpose ANFO product for hard rock stoping applications, bord & pillar and easier development conditions. Expanfo™ 200 is ideal to limit over-break or excessive fines.

expanfoTM300 Expanfo™ 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 the same.

** 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.

products (RWS = 1). However, actual detonation performance of ANFO products deviates significantly from this ideal. Expanfo™ products detonate closer to the ideal due to the inclusion of the sensitising microballoons. The in-hole density

decreases from Expanfo™300 to Expanfo™100.
