Paste tail<strong>in</strong>gs<br />
Tail<strong>in</strong>gs slurry thickened <strong>to</strong> a paste consistency, with a high yield stress, and reduced<br />
slump and bleed water. Cement is added <strong>to</strong> produce cemented paste tail<strong>in</strong>gs backfill for<br />
underground m<strong>in</strong>e s<strong>to</strong>pes.<br />
Percolation<br />
The seepage of <strong>in</strong>filtration <strong>to</strong> the receiv<strong>in</strong>g environment.<br />
Personal safety<br />
Preserv<strong>in</strong>g the safety of m<strong>in</strong>e site personnel and the general public <strong>in</strong> the face of m<strong>in</strong>e site<br />
risks of <strong>in</strong>jury.<br />
Piezometers<br />
Sensors used <strong>to</strong> moni<strong>to</strong>r groundwater mound<strong>in</strong>g beneath and surround<strong>in</strong>g a tail<strong>in</strong>gs<br />
s<strong>to</strong>rage facility.<br />
Pioneer species<br />
The first species <strong>to</strong> colonise an area of disturbance.<br />
Pip<strong>in</strong>g<br />
The formation of an erosion tunnel through an earthen structure due <strong>to</strong> the <strong>in</strong>duced flow of<br />
water through it.<br />
Post-m<strong>in</strong><strong>in</strong>g land use<br />
Term used <strong>to</strong> describe a land use which occurs after the cessation of m<strong>in</strong><strong>in</strong>g operations.<br />
Power station or fly ash<br />
A by-product of the production of electricity from coal-fired power stations.<br />
PPV<br />
Peak particle velocity (ppv) is a measure of ground vibration magnitude and is the<br />
maximum <strong>in</strong>stantaneous particle velocity at a po<strong>in</strong>t dur<strong>in</strong>g a given time <strong>in</strong>terval <strong>in</strong> mms-1.<br />
(Peak particle velocity can be taken as the vec<strong>to</strong>r sum of the three component particle<br />
velocities <strong>in</strong> mutually perpendicular directions)<br />
Precautionary pr<strong>in</strong>ciple<br />
If there are threats of serious or irreversible environmental damage, lack of full<br />
scientific certa<strong>in</strong>ty should not be used as a reason for postpon<strong>in</strong>g measures <strong>to</strong> prevent<br />
environmental degradation.<br />
Probability cost<strong>in</strong>g<br />
Estimates of value (cost or benefit) that account for the likelihood of occurrence and the<br />
range of values of the outcome - values are expressed through a statistical analysis (e.g.<br />
Monte Carlo simulation) us<strong>in</strong>g a statistical distribution over the range of possible values<br />
account<strong>in</strong>g for the probability and tim<strong>in</strong>g of the event occurr<strong>in</strong>g.<br />
Process stewardship<br />
Involves a program of actions focused on ensur<strong>in</strong>g that processes, such as beneficiation,<br />
flocculation, crush<strong>in</strong>g, gravimetric separation, and others that are used <strong>to</strong> produce ores,<br />
concentrates and other m<strong>in</strong>eral products are undertaken <strong>in</strong> a socially and environmentally<br />
responsible manner.<br />
