Study on comprehensive treatment and ecological restoration project of Tuling mine dump

Because Tuling kaolin mine not strictly dumped according to the design in past mining process,it is made the mine geological environment problems produced by the dump,such as landslide and debris flow and ecological environment destruction,etc,are increasing sharply.It will directly constitute a serious threat for mine highway,the lives and property of the local residents.On the basis of field investigation and the mine engineering material,firstly the sliding failure modes of the dump are analyzed,and then the integral and local stabilities of the dump are calculated.Comprehensive considering the topography and stratigraphic lithology of the dump,the stability analysis results,etc,in accordance with the principle of the feasible in technology and reasonable in economy,the comprehensive control project scheme is put forward,namely "cutting slope and reducing load+masonry retaining wall+masonry skeleton plant grass+cut drainage+monitoring".After the scheme is implemented,already through the monitoring of two hydrological year,and the stability of the dump is in good condition.The implementation of the scheme not only effectively eliminates the geological disaster safe hidden trouble of the dump,but also fully recovers the ecological environment of the dump.
