Introduction<br />

M<strong>in</strong><strong>in</strong>g operations <strong>in</strong> Australia and <strong>in</strong>ternationally cover a range of commodities,<br />

sizes, and methodologies. The Australian m<strong>in</strong>erals sec<strong>to</strong>r is <strong>in</strong> the <strong>to</strong>p five producers<br />

of most of the world’s key m<strong>in</strong>erals commodities <strong>in</strong>clud<strong>in</strong>g<br />

The world’s <strong>lead<strong>in</strong>g</strong> producer of bauxite, alum<strong>in</strong>a, rutile, and tantalum.<br />

The second largest producer of lead, ilmenite, zircon and lithium.<br />

The third largest producer of iron ore, uranium, and z<strong>in</strong>c.<br />

The fourth largest producer of black coal, gold, manganese and nickel.<br />

The fifth largest producer of alum<strong>in</strong>ium, brown coal,<br />

diamonds, silver and copper (MCA).<br />

Australian m<strong>in</strong><strong>in</strong>g methods range from surface m<strong>in</strong><strong>in</strong>g that may <strong>in</strong>clude strip<br />

m<strong>in</strong><strong>in</strong>g with dragl<strong>in</strong>es; truck and shovel or conventional open pits; and alluvial or<br />

placer m<strong>in</strong><strong>in</strong>g, <strong>in</strong>clud<strong>in</strong>g dredg<strong>in</strong>g for m<strong>in</strong>eral sands, precious metals and gems.<br />

Underground coal m<strong>in</strong><strong>in</strong>g ranges from longwall and bord and pillar while cav<strong>in</strong>g and<br />

s<strong>to</strong>p<strong>in</strong>g methods are most common <strong>in</strong> hard rock m<strong>in</strong><strong>in</strong>g. Apart from “m<strong>in</strong><strong>in</strong>g”, this<br />

chapter will also highlight susta<strong>in</strong>ability issues associated with m<strong>in</strong>eral process<strong>in</strong>g,<br />

metallurgical operations and occasionally ref<strong>in</strong>ery operations.<br />

Each of these methods may result <strong>in</strong> significant potential impacts on the susta<strong>in</strong>ability<br />

of m<strong>in</strong><strong>in</strong>g operations and thus each operation demands the highest level of<br />

management skills <strong>to</strong> m<strong>in</strong>imise any negative impacts. This Chapter covers <strong>lead<strong>in</strong>g</strong><br />

<strong>practice</strong> <strong>in</strong> susta<strong>in</strong>ability dur<strong>in</strong>g the production or operations stage of the m<strong>in</strong><strong>in</strong>g cycle.<br />

It is dur<strong>in</strong>g this phase that the benefits or costs of the plann<strong>in</strong>g decisions implemented<br />

dur<strong>in</strong>g the earlier phases are realised. This is also the phase of m<strong>in</strong><strong>in</strong>g where the<br />

greatest potential impacts on the environment and the community occur.<br />

Airborne Contam<strong>in</strong>ants, Noise and Vibration<br />

A recent newspaper article (Safe, 2009) highlighted the issue of noise and its<br />

impacts, both real and perceived on the local community. The article detailed the<br />

recent formation of an anti-noise lobby group – Noise Watch Australia. One featured<br />

case <strong>in</strong>volved a retiree who moved <strong>to</strong> a heavily timbered block some distance from<br />

a capital city. A sawmill <strong>in</strong>creased its production <strong>to</strong> 24 hours, 7 days a week. In<br />

his words, “the noise drove us darn crazy” and consequently he sold up. Another<br />

compla<strong>in</strong>ant stated “the growth of noise <strong>in</strong> communities across Australia is still not<br />

recognized for what it is – another form of pollution that’s hav<strong>in</strong>g serious health<br />

impacts on many people”. The World Health Organisation was quoted <strong>in</strong> the article<br />

as say<strong>in</strong>g that up <strong>to</strong> three per cent of heart disease deaths, or more than 200,000<br />

globally, are due <strong>to</strong> long time exposure <strong>to</strong> chronic traffic noise.<br />
