In modern mining engineering, especially in the field of gold mining, the requirement of environmental protection is increasing day by day. Among them, gold mine geomembrane plays a great role in environmental protection.
We must first understand what is gold geomembrane. This is a high density polyethylene (HDPE) material made of impermeable layer, with extremely high chemical stability and anti-aging properties, can effectively prevent groundwater pollution and tailings leakage and other problems. Then we need to know exactly where it is used:
1. Anti-seepage of tailings reservoir: anti-seepage treatment of tailings dam foundation to avoid harmful substances from penetrating into groundwater.
2. Flange area isolation: Laying geomembrane in the flange area can effectively prevent direct contact between soil and ore and reduce environmental impact.
3. Pile leaching site covering: Use its good corrosion resistance as the upper cover of pile leaching site to reduce the risk of environmental pollution.
So, how to use gold mine geomembrane correctly?
The correct construction steps are as follows:
a) Site preparation: ensure that the base is smooth and solid, and remove sharp objects;
b) Film material positioning: accurate lofting according to the design drawings, and adjust the appropriate size;
c) Laying and installation: laying by professionals, pay attention to keep enough slack to prevent pulling too tight resulting in damage;
d) Joint welding: the use of hot melt or adhesive for tight joint connection;
e) Inspection and testing: including visual inspection and pressure detection to confirm that there are no leakage points;
