Guolanggou tailings pond of Tibet Huatailong Mining Development Co.,Ltd.is the tailings pond supporting Jiama Phase 2 Project and takes the form of early dam+paste upstream dam formation.During operation,the tailings have low permeability coefficient and doesn’t solidify,besides,the burial depth of dam seepage line is only about 10 m.By applying air-driven drainage technology,vertical and horizontal drainage pipes with special structure are evenly arranged on the dam body.The joint process of high-pressure air-driven and gravity flow method for drainage greatly improves the drainage efficiency of the dam,the burial depth of dam seepage line rapidly decreases to about 20 m,and the dam stability is improved.Air-driven drainage technology effectively solves the solidification problem for drainage in the sub-dam of Guolanggou tailings pond,and at the same time,provides reference for dam construction with paste tailings and drainage technology.
