Taking fine tailings dam in Longdu Tailings Pool as an example,the stability of the dam with various situations while earthquake with seven magnitude takes place there.

In light of the difficult problems of fine tailings damming in Jianshan concentrator, the damming technology are applied successfully using hydrocyclone to fine tailings damming through selection of design schemes.

Taking the materials of the fine tailings from Longdu tailings pond as a case study,the model,based on the design tailings dam of Longdu tailings pond,was performed to study the stability of fine grained tailings dam in two situations,with and without geo-grid reinforcement.
