Abstract: According to 2012 statistics,a total of 152 ownerless tailing ponds in Guangxi are diseased / dangerous tailing ponds,the library closure procedure makes the slow closure work progress of ownerless tailings pond.According the scale(the dam height for H and the storage capacity for V) of tailing ponds in Guangxi and sampling for field survey,the condition of bad present situation but low damage degree and disposal difficulty for small scale ownerless tailings pond has been found.Therefore the ownerless tailings pond in Guangxi has been divided into 3 types which is the miniature ownerless tailings pond( H＜3 m or V＜5×10⁴m³),the ordinary small-scale ownerless tailings pond(3 m≤H＜10 m and 5×10⁴m³≤V＜10×10⁴m³) and the common ownerless tailing pond( H≥10 m or V≥10×10⁴m³).On this basis,with reference to the related policies and regulations for tailing pond closure in the National and the other provinces,3 kinds of closure procedure which is the "simple" closure procedure,the "ordinary simple" closure procedure and the "normal" closure procedure have been put forword.Among them,47% ownerless tailing ponds in Guangxi would refit by the "simple" or the "ordinary simple" closure procedure.By adopting expert on-site audit instead of closure design,the problems of ownerless tailing ponds in Guangxi which are information incomplete,closure procedure library and lack of funds have been solved.The results can provide a reference for the hidden hazards control and tailing pond closure of the ownerless tailing ponds in Guangxi and the other provinces.
