The ground immediately surrounding the opening of a drill hole.

In underground terminology the collar may also refer to the uncharged length of the blast hole as below.

The charging of a drill hole with a continuous charge.

Those groups of explosives which can be stowed or carried together without significantly increasing either the probability of an accident or, for a given quantity, the magnitude of the effects of such an accident. On this criterion, explosives have been divided into a number of compatibility groups, each denoted by a code letter from A to L (excluding I), N and S.

(For further information see the Australian Dangerous Goods Code or the Australian Code for the Transport of Explosives by Road and Rail.)

For commercial blasting explosives the relevant compatibility groups are:

• D - Secondary explosives, may burn may explode
• B - Primary explosives, will explode
• S - Packaging contains the effects of any explosion

Notes:

It is because D (secondary explosives) and B (primary explosives) cannot be stored together (incompatible) that requires separate HE and Detonator magazines.

The Hazard Division is often used with compatibility group. Hazard division refers to the type of explosion hazard that exists. The Hazard Divisions that are relevant to shotfirers are:

• 1 - Mass explosion hazard
• 4 - No significant risk of a mass explosion hazard

Typical codes and examples are shown below:

The authority having jurisdiction for administering legislation covering the manufacture, transport, storage and handling of dangerous goods and / or explosives within a particular State or Territory. There may be more than one authority in an ANE supply chain.

A person who has acquired through training, qualification, experience or a combination of these, the knowledge and skill enabling that person to correctly perform the task.

A compliance audit is a comprehensive review of an organization's adherence to defined policies, procedures and guidelines. Audit reports evaluate the strength and thoroughness of compliance preparations, security policies, user access controls and risk management procedures over the course of a compliance audit

A specially designed portable source of electrical energy used to fire electric detonators.

Exel™ Connectadet™ Detonators are signal tube based detonators designed to control the millisecond delay sequence from hole to hole, across the surface of a blast.

The presence of an alert and authorised person or the continuous monitoring by video or electronic surveillance.
