Classification of tailings storage safety

The safety of the tailings pond is mainly determined according to the flood control capacity of the tailings pond and the stability of the tailings dam body. It is divided into four levels: dangerous reservoir, dangerous reservoir, disease warehouse and normal reservoir.

The tailings pond has one of the following conditions:

The flood discharge system is severely blocked or collapsed, and the drainage capacity or drainage capacity is drastically reduced;

Empirical calculation, the minimum safety factor of the anti-sliding stability of the dam is less than the specified value of 0 95;

The tailings reservoir has a serious shortage of flood storage capacity. When designing the flood level, the safety super-high and the minimum dry-tank length do not meet the design requirements, and flooding may occur.

The drainage wells are significantly inclined and there are signs of collapse;

Other serious threats to the safe operation of the tailings pond.
