Reveal the main points of safety inspection of tailings dam

Article 7. 2. 1 of Technical Specification for Safety of Tailings Pond (AQ 2006) reveals the key points of safety inspection of tailings pond for you. From the outline size of the dam to the protection of the dam surface, every detail is spared.

Overall dimension of dam

The dimension of tailings dam is one of the important contents of safety inspection. During the inspection, parameters such as dam height, dam top width and dam bottom width should be tested to ensure that they meet the specified standards.

Dam surface protection

Dam surface protection is an important part of tailings dam safety inspection. During the inspection, measures such as anti-seepage, anti-scour and wind protection should be tested to ensure their effectiveness and reliability.

Displacement monitoring

Displacement monitoring of tailings dam is one of the important contents of safety inspection. Line of sight method and forward intersection method can be used for inspection, at least four times a year, and it needs to be increased when there is abnormality.

Water level monitoring

Water level monitoring of tailings dam is one of the important links of safety inspection. During the inspection, the flood level and groundwater saturation line should be monitored at least 1 time every quarter, especially in the case of heavy rain or abnormal water level.
