Description
Technical field
The present invention relates to a kind of Tailings Dam percolate pump drainage system and its construction methods, belong to mine capital construction construction field.
Background technology
Tailings Dam is to store up metal or non-metal mine tailing or other works by building a dam or exclosure mode is formed
The place of industry waste residue.It is discharged into from ore dressing plant in the tailing of Tailings Dam often containing toxicant or heavy metal ion, contains to avoid
Poisonous and harmful substances polluted underground water must be laid with antiseepage film in Tailings Dam and do Anti-seeping technology.
In reality, the large area antiseepage film of laying in Tailings Dam, it is understood that there may be manufacturing defect, transport is damaged and welding is broken
Bad, cutting damage, ground puncture destruction etc. are a variety of to lead to the factor that antiseepage film leaks, moreover, the mine period of service is longer, oozes
It is more to leak position, percolate is spread from Tailings Dam bottom to deeper inside and Tailings Dam surrounding, inevitably polluted underground water
Body and surrounding enviroment.Therefore, it is necessary to the percolate under film is carried out to collect and outer row in time.Seepage tends to occur at tailing
After accumulation, antiseepage film stress, however, accumulating a large amount of tailing in Tailings Dam, difficulty is brought to percolate pump drainage.
At present, common leakage of leachate detection and pump drainage method are underground water detection method.Underground water detection method is in tail
Setting sump on the outside of the dam body in ore deposit library detects whether antiseepage film leaks simultaneously pump drainage percolate by extracting the water of sump.
However, underground water detection method has the disadvantage that：Due to being arranged on outside library, finding the time of leakage has longer lag；And it sets
The sump quantity put will not be too many, it is impossible to ensure that percolate is bound to flow into sump, and increase sump quantity, expense compared with
It is high.Therefore, it is necessary to the detection of existing effusion and pump drainage method are improved.
