Primary cause of Dam Failures Recent study
The primary cause of dam failures in mining operations is often related to issues of stability and structural integrity. One common issue is related to the compaction and stabilization of waste materials.
When waste materials are not properly compacted and stabilized, they can become unstable over time, which can lead to liquefaction and subsequent failure of the dam.
For example, in 2019, a mining waste dam in Brazil failed, leading to a catastrophic collapse that killed over 270 people. The dam was built with a design that was not able to withstand the weight of the waste materials, which caused the dam to fail due to instability and liquefaction.
Another issue that can contribute to the failure of a mine waste dam is improper design or construction. This can occur when the dam is not designed with proper safety factors, or when construction is not carried out to the required standards.
Inadequate maintenance and monitoring can also contribute to the failure of a dam, as problems may go unnoticed or unaddressed until they become critical.
For example, in 2014, a mining waste dam in British Columbia, Canada, failed due to a design flaw that was not detected during construction. The dam was built with a slope that was steeper than recommended, which caused it to fail under the weight of the waste materials.
The failure resulted in the release of millions of cubic meters of waste materials into nearby waterways. In conclusion, the primary cause of dam failures in mining operations is often related to stability and structural integrity issues.
Proper compaction and stabilization of waste materials, appropriate design and construction, and adequate maintenance and monitoring are all critical factors in ensuring the safety and stability of a mine waste dam.
