Modern methods for recultivation of tailing dumps

摘要

Lands resulting from the flotation tailings and disposal of tailing have no biotic potential, so it is necessary to apply modern methods for remediation forudthese lands to have a particular purpose. To have a successful recultivation, it is necessary first to remove the water from the tailing dump. Dewatering can be done byudseveral methods depending on the application/usage of the terrain after recultivation. The process of dewatering can be performed by application of geotextile with wovenudgrid, and then adding burden on tailing dumps or by preparing vertical piles and adding of the burden. If at site where tailing dump is situated, buildings are foreseen toudbe constructed it is necessary the tailing dump to meet the geo mechanical conditions. During the recultivation of tailing dumps it is best if flotation tailing is completelyudisolated from humus material by placing geosynthetic materials (geotextiles, geomembrane, drainage geocomposite, geogrid). Hence, before applying humus geosyntheticudmaterials are placed, and isolation of tailings, stable conditions, erosion protection are accomplished. For more successful emergence of vegetation on the slopes of tailinguddumps modern material Biomac S/C can be used, material made of coconuts and straw merged with polypropylene network which material is used for the recultivation inudRepublic of Macedonia and excellent results are achieved.
