Abstract: In order to better conduct the land reclamation plan of ionic rare-earth mine in Southern China,characteristics of land destruction was introduced based on the land reclamation plan on compiling regulation.Taking an ionic rare-earth mine as a case,the land destruction of this type of mine was introduced,and the design characteristics in reclamation time sequence,overburden stripping and stockpiling,in-situ leaching mining stope drainage engineering,risk fee,etc were summarized,comparison between different reclamation method was conducted.It can be concluded that ionic rare-earth reclamation includes two areas:land that will be destroyed and that have already been destroyed.For land that will be destroyed,influence of leaching solution leaking on plant roots and groundwater was considered combined with in-situ leaching characteristics,and water collecting and drainage system and extracting risk fund should be emphasized; For land that have already been destroyed,investigation on characteristics,degree,size and site condition of land being damaged should be made,combining with the current situation of abandoned mining area.

Key words: Ionic rare-earth mine, In-situ leaching mining method, Land reclamation
