-
Abstract
Paste stockpiling is a new method which was used for tailings disposal in tailing pond. It is also applied in the tailing pond of BaoGang West Mine. The stability of tailings dam is the key factor that making sure the safety of paste stockpiling. By using Geo-Studio software and based on the tailing pond of BaoGang West Mine the impact of different depth of water on the south dam stability were analyzed. The stability of north dam, in different height of tailings, were studied. In order to prevent possible failure of south dam, the depth of water is suggested no more than 8m, otherwise measures should be taken to reinforce the south dam. The north dam is always safety no matter on the condition of 8m accumulation height or 23m accumulation height.
