ÇÖPLER GOLD MINE RETAINING WALLS

The traditional concrete systems that are common in the mine fields are rigid structures. Due to continious high vibrations, cracks occur in the concrete structures. These structures that cannot adopt to the changing environmental conditions are replaced with geogrid reinforced retaining structures which are environmentally friendly, flexible and techologically new products. For this reason, Anagold has decided to use, systems developped by Maccaferri Turkey, the leader in the mining field for such solutions. After calculating the overturning, sliding, internal and external stability analysis with MacStars-W, a software that can analyse the interaction of geogrids with gabion baskets, Maccaferri Turkey had decided that the most appropriate retaining structure is the Terramesh System reinforced with ParaLink geogrids. In pratice, a backfill material of crushed stone having a maximum particle size of 76mm known as structural fill, has been laid and compacted in layer thicknesses of 25-33cm. After the calculations it has been determined that ParaLink 300kN and 200kN geogrids shall be installed with a 1m vertical spacing at the bottom and 2m vertical spacing on top of the walls. The 20m high grinder and 14m high crusher walls having a total surface area of 4685m2 was constructed in 4 months. Terramesh System Retaining Wall will continue to work continuously with its flexible and robust structure in Erzincan province, which is a region where seismic forces can be encountered continuously.
