Method for improving safety coefficient of tailing pond based on segmented damming
The invention discloses a method for improving the safety coefficient of a tailing pond based on segmented damming. The method comprises the following steps: (1) grading; (2) fine fraction discharge naturally settles according to the size of the fraction; (3) discharging the micro-fine particles to the last several sections; (4) coarse-fraction pumping is carried out at the dam head for stacking; (5) the upper layer coarse fraction compacts the lower layer fine fraction; (6) damming step by step according to the slope ratio; and (7) on-line monitoring of the infiltration line. The method is simple in process, remarkable in effect and capable of improving the safety coefficient of the tailings pond.
