What is the recommended practice after heavy rainfall regarding highwalls?

Frequent examinations of highwalls after heavy rainfall are recommended as a best practice to ensure the safety of mining operations. Heavy rainfall can lead to increased soil saturation and potential instability of the highwall, which may result in rockfalls or landslides. By conducting examinations, personnel can assess the conditions and identify any changes or hazards that may have developed due to the rain.

Regular inspections allow for timely detection of signs of instability, such as cracks, bulges, or changes in drainage patterns, providing an opportunity to take corrective actions to mitigate risks. This proactive approach is crucial for maintaining a safe working environment and ensuring that all safety protocols are adhered to. Thus, prioritizing frequent examinations is both a precautionary measure and a critical aspect of operational safety in mining.
