Leveraging data for the safety of tailings storage facilities – TSF
The devastating effects of tailings storage facilities (TSF) failures cannot be overemphasized. Hence, every means that can ensure TSF stability, safe operations, and closure should be explored and exploited to the fullest. In the past, TSF safety has largely been reliant on historic information of similar facilities, manual monitoring and measurements, and interpretation of data based on their face values. This has led to disastrous TSF failures. In this data age, this should not be allowed to happen. Diligent collection of real-time data, application of machine learning methods to analyze the data, and appropriate intervention/remediation can make TSFs operations and closure safer. The use of machine learning for data analytics can reveal very useful hidden insights in complex TSF datasets. Engineers with this information can then proactively stabilize TSFs and make them safer. To be able to exploit the full potential of data for TSF safety, accurate collection of relevant data is the first step. The next step is the application of the appropriate data analysis procedure (machine learning methods) to the datasets. Proper interpretations of the analysis results will reveal valuable information on TSF safety for possible intervention. This talk will highlight the importance of accurate real-time data collection and analysis in safe TSF operations and closure.
