• Description:
  Predicting slope behaviour over time is a crucial geotechnical engineering task for open pit mines. Information gathered from monitoring practices is used to anticipate the potential failure of a slope mass, giving mine sites the ability to safely operate with minimal interruption. Correct monitoring procedures and an understanding of failure mechanisms assist with accurately predicting slope failures. This is key to improving the safety of miners, property, and production at a mine site. Current techniques used for prediction, such as statistical learning models, are unable to provide accurate results due to the uncertainties of slope attributes needed. In response, many mines and researchers are gathering and using small, unbalanced data sets that may require complex processing algorithms to try to extract useful information. To address this limitation, researchers at the Spokane Mining Research Division (SMRD) of the U.S. National Institute for Occupational Safety and Health (NIOSH) teamed up with industry partners to investigate the current state of public slope failure databases and outline a proposal for a new comprehensive slope failure evaluation database. The development of a comprehensive database that includes existing data and is continually updated with new entries from mine sites around the globe would help to better understand slope behaviour, determine slope instability alarm settings, and estimate time of failure. This work is a part of NIOSH's Open Pit Highwall Safety project. [Description provided by NIOSH]
