Fortis ™ Advantage System

Technical Data Sheet

Description The Fortis™ Advantage Bulk System of sensitised pumped emulsion blends has been designed for use in wet blasting applications. Application Fortis™ Advantage has been specifically tailored for use in open cut hard rock mining. Fortis™ Advantage can be used whenever wet blast holes are encountered. It is not suitable for ground containing reactive sulphide. Key Benefits • Fortis™ Advantage is reliable in dry and wet blastholes. • The integrated product and delivery systems of the

Fortis™ Advantage Bulk System ensures accuracy, productivity and dependability of supply.

• Fortis™ Advantage is only sensitized in the borehole by chemical gassing.

• Fortis™ Advantage can be loaded at varying energies and densities to maximise fragmentation and improve mine to mill productivity.

• Fortis™ Advantage provides fully coupled explosive charges to maximise blasting outcomes.

Recommendations for Use Blasthole Charge Length Fortis™ Advantage is suitable for use in holes of up to 30 m in length, depending on hole diameter, product density and presence of water. Please contact your local Orica representative for further information. Priming and Initiation Fortis™ Advantage must be in direct contact with an appropriately sized Senatel™ packaged explosive or Pentex™ booster. The use of detonating cord may adversely affect the performance of the Fortis™ Advantage series and could result in misfires. Consult an Orica Technical Representative before attempting to use with detonating cord. Charging Fortis™ Advantage is part of the range of bulk explosives delivered by Orica's Mobile Manufacturing Units (MMU™). Fortis™ Advantage is manufactured on the MMU™ and pumped into blastholes on demand. Gassing Time Allow at least 30 minutes between loading and stemming blastholes.

Fortis ™ Advantage System

Technical Data Sheet

Disposal Disposal of explosive materials can be hazardous. Methods of safe disposal of explosives may vary depending on the user’s situation. Please contact a local Orica representative for information on safe practices. Safety Fortis™ Advantage is relatively insensitive to accidental initiation by shock, friction or mechanical impact under normal conditions of use. Detonation may occur from heavy impact or excessive heating particularly under conditions of confinement. Explosives based on Ammonium Nitrate such as the Fortis™ Advantage may react with pyritic materials in the ground and create potentially hazardous situations. Orica accepts no responsibility for any loss or liability arising from use of the product in ground containing pyritic or other reactive material. Trademarks

Notes

1. Nominal Density Only.

2. Contact your local Orica Representative for further advice on

loading at minimum hole diameters.

3. VOD will depend on application including explosive density

blasthole diameter and degree of confinement. The VOD range

is based on minimum unconfined and calculated ideal.

4. REE is the Effective Energy relative to ANFO at a density of

0.8 g/cm3. ANFO has an effective energy of 2.30 MJ/kg.

Energies quoted are based on ideal detonation calculations

with a 100 Mpa cut off pressure. Non-ideal detonation energies

are also available on request. These take account of blasthole

diameter, rock type and explosive reaction behaviour.

5. Carbon dioxide is the main greenhouse gas produced. The

output is calculated assuming ideal detonation.
