A

Adjusted Net Explosive Quantity (Adjusted NEQ)

The mass of TNT that would produce an equivalent explosive effect to the inventory under consideration.

AEISG MPU Code

The Australian Explosives Industry Safety Group (AEISG) publishes a number of Codes of Practice for the explosives industry including a code for Mobile Processing Units (MPU's).

Other codes are found at www.aeisg.org.au

Agglomerate

A mass of angular volcanic fragments united by heat.

silurian agglomerate

Entry link: Agglomerate

Air Blast

Vibration of the atmosphere due to the release of explosives energy.

The three main sources of airblast are rock release pulse, stemming release pulse and rock piston effect.

  1. Rock release is where the face bursts due to inadequate burden.
  2. Stemming release is due to rifling or cratering of the blast hole collar.
  3. Rock piston is the large, low frequency, movement of air driven by the movement and swelling of the blasted rock mass.

ALANFO

ALANFO A mixture of ANFO and aluminium powder. Adding aluminium increases the strength. As aluminium is a fuel a reduced quantity of diesel is required.

Ammonium Nitrate

Ammonium Nitrate (AN), meeting the requirements of UN1942.

The chemical compound ammonium nitrate, the nitrate of ammonia with the chemical formula NH4NO3, is a white crystalline solid at room temperature and standard pressure. It is commonly used in agriculture as a high-nitrogen fertilizer, and it has also been used as an oxidizing agent in explosives, including improvised explosive devices. It is the main component of ANFO and emulsion explosives which account for over 80% explosives used in Australia.

AN used for ANFO manufacture is referred to as PPAN meaning Porous Prilled Ammonium Nitrate.

Prilled is the term for a small aggregate of a material, most often a dry sphere, formed from a melted liquid

Porous because the prills contain voids to soak up the diesel fuel.

Amps

Amperage or Amps provided by an electrical service is the flow rate of "electrical current" that is available. 

Basic Formulas Relate Voltage, Current (Amps), & Resistance (Ohms or Ω ), Watts

Voltage = Current x Resistance

Current = Voltage / Resistance

Resistance = Voltage / Current

Watts = Volts x Amp

Entry link: Amps

ANE

An ammonium nitrate based emulsion, suspension or gel which meets the requirements of UN3375 under the UN (United Nations) classification system.

Entry link: ANE

ANE Associated Works

Offices, workshops, stores, ablutions and the like directly associated with the operation of the ANE premises.

Entry link: ANE Associated Works

ANE Premises

Any designated land, building, or area that is used for the storage, manufacture or handling of ANE. A fence may or may not form, or be part of, the boundary of the premises.
