• levels of noise, dust <strong>and</strong> vibration;<br />

• solid <strong>and</strong> liquid waste management;<br />

• visual quality; <strong>and</strong><br />

• the management of natural, historical <strong>and</strong> archaeological sites<br />

of significance.<br />

Management of larger sites can be simplified by classifying the area into<br />

l<strong>and</strong> units, which have different environmental characteristics <strong>and</strong><br />

sensitivities <strong>and</strong> must be managed accordingly.<br />

Examples of l<strong>and</strong> units are:<br />

• gibber plains;<br />

• s<strong>and</strong> dunes;<br />

• frontal dunes;<br />

• drainage lines;<br />

• salt lakes;<br />

• s<strong>and</strong> plains; <strong>and</strong><br />

• alluvial flood plains, etc.<br />

3.3 Site Plan<br />

Many of the potential adverse impacts of mining operations can be<br />

avoided or reduced by careful siting of the proposed operation. The<br />

physical elements of the site discussed in 3.2 are fixed, as is the location<br />

of the ore body itself. Preparation of a site plan, preferably in the form of<br />

a number of themes within a Geographic Information System (GIS), or a<br />

series of overlays from an air photo or detailed topographic map,<br />

enables the clear identification of the important physical elements of the<br />

site including environmentally sensitive locations. Positioning of site<br />

infrastructure <strong>and</strong> mining procedures can then be determined to:<br />

• protect access to the ore body <strong>and</strong> any possible extensions;<br />

• optimise haul distances for ore <strong>and</strong> overburden;<br />

• avoid impacts on environmentally sensitive locations or l<strong>and</strong> units;<br />

• minimise disturbance beyond the mine excavation <strong>and</strong> avoid steep<br />

cuts <strong>and</strong> fills or other extensive earthworks;<br />

11<br />

• minimise the noise <strong>and</strong> visual impacts (including lights) on adjacent<br />

l<strong>and</strong> users;<br />

• develop a site drainage plan; <strong>and</strong><br />

• optimise the configuration of the mined areas to accommodate the<br />

proposed post-mining l<strong>and</strong>-use.<br />

In areas where the potential for visual <strong>and</strong> noise impacts is large,<br />

provision to reduce impacts <strong>and</strong> remedial works can be incorporated<br />

into the site plan. Some examples of site planning are illustrated in<br />
