scope:

This Standard applies to the design, installation and operation of electrical plant and equipment installed at surface mining and quarrying operations, the surface of underground mines, and associated processing plants.

There are particular requirements for the following:

(a) The operation of equipment and personnel interacting with electrical installations.

(b) Trailing cable fed machinery used for digging/winning product (i.e. electric draglines, electric face shovels, floating dredges, and electric drills), and transporting, stacking and reclaiming product (i.e. conveying systems, balance machinery such as stackers and reclaimers).

(c) Power generation and distribution equipment used to supply trailing cables and relocatable plant.

(d) Power and distribution on IT (impedance earthed) systems, TN and TT systems.

(e) Earthing systems for power distribution to underground mines.

(f) Overhead lines on a mine site.

(g) Relocatable plant and buildings.

(h) Fixed plant.

This Standard does not apply to the following areas:

(i) Earth moving machinery covered by ISO 6165 and not fed by trailing or reeling cables.

(ii) The design of mine winder control systems.

The Standard describes the types of electrical distribution systems.

This Standard supplements the requirements of AS/NZS 3000, AS 2067, and AS 60204 for installations in the harsh environments found in mining and quarrying operations.

Where equipment is located on the surface and there is conflict with the AS/NZS 4871 series, this Standard takes precedence.

NOTES:

1 The requirements of this Standard may be read in conjunction with, but do not take precedence over, regulations of a regulatory authority that may apply in a specific area.

2 In some instances, State legislation refers to parts of the previous version of this Standard, therefore it is important to note that these parts have now been combined into the one document.
