Airborne particulate matter ranging in diameter from 10 to 50 microns.

Water that is in motion (i.e. flowing water).

A blast hole may be considered to contain dynamic water where the recharge rate is more than 1 m per hour.
Holes containing dynamic water cannot be dewatered and should be loaded with a pumped, water resistant product.

The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much more rapidly, and explode in a much more precise timing after the electric current is applied, by the process of exploding wire method.

EBW Detonation Construction (typical)

Diagonal line of blastholes in a staggered pattern.

Thrown out violently.

A detonator designed for, and capable of, initiation by means of an electric current.

The electric current is generally supplied by a Condensor Exploder.

An Electronic Delay Detonator (EDD) consists of a conventional base chage detonator with a programmable initiating module inserted.

Electronic detonators look similar to electric detonators but have a plastic connection on the end of the leg wires rather than being shorted and sheathed.

Nonelectric detonator complete with delay train components, before assembly onto signal tube.

As defined in the Australian Code for the Transport of Explosives by Road and Rail (known as the AEC Code).

Explosives consisting of droplets of a saturated aqueous solution containing oxidizing salts, suspended in an oil/wax matrix, and other additives.
They can be either cap or non-cap sensitive, depending on their composition.

Emulsion explosives consist of small droplets of water containing dissolved AN surrounded by a fuel phase. These are of the water in oil type.

Water in oil emulsions are water resistant because the oil phase covers and protects the water phase from being diluted by external water. 

Emulsion explosives can be both bulk and packaged.
