For there is the slope dam of water, such as Tailings Dam (or dam), there are a large amount of Tailings Slurries precipitating water in Tailings Dam, meanwhile,
When from tailing dam dam crest tailing disposal, during ore pulp trickles into library, ore pulp water constantly permeates downwards；In addition, flood season is big
Measure rainfall.These factors form a huge seepage field in tailings dam.Furthermore tailing lithosomic body belongs to non-mean value body, ore discharge
Position needs often to exchange again；Dam body is constantly increasing again；Moreover in the entire viability of Tailings Dam, mineral resources and beneficiation flowsheet
It is possible that changing, tailing performance can naturally also change.The reason of here it is Seepage Field of Tailings Dam complexes.Saturation, that is, seepage flow

Whether library flood control capacity meets safety requirements.Specifically: a perfect design can provide needed for flood control in design text
Tune flood it is deep, and require at design flood level (i.e. extreme high water), the minimum safe that meet design code simultaneously is super
High and minimum safe does the requirement of beach length.If the minimum safe superelevation and minimum safe that are not specified by design text do beach
Length can use minimum safe superelevation and minimum safe specified in design specification to do beach length as foundation.Reservoir level monitoring
As a result if the tune flood for not being able to satisfy design is deep, minimum safe superelevation and minimum safe do beach length, production manager is just
Reservoir level is reduced by every means, until meeting design requirement.Thus control reservoir level is to ensure that Safety of Tailings Dam degree
An extremely crucial measure for flood.

Indicator reaction is seen, therefore for the grasp of slopes downstream slope deformation, can find dam deformation rate and development speed in time, be conducive to
Safety regulator and enterprise carry out the Emergency decision of science, and take Emergency Countermeasures measure in time, to avoid the hair of disaster
It is endangered caused by raw or reduction disaster generation.Fig. 3 is the typical variant polar plot on side slope mine dam, as we know from the figure dam body downstream
The deformation for downwards and being biased to downstream occurs for slope.
