| Abstract: | The frozen soil in tailings pond may causes seepage line rising or local transgression and generates dam instability problem. The calculating method of frozen in winter tailings fill dam was put forward , and the characteristics and harm in detail of frozen soil and winter ore-drawing in tailings pond was discussed in this paper. Material protective measures was put forward based on calculation for the designing reference for the related personnel. |
