What is a major hazard of working near highwalls?

Working near highwalls presents a significant risk due to the possibility of rock falls. Highwalls are the steeply sloped sides of an open-pit mine, which can be unstable due to weathering, mining operations, and geological conditions. These factors can cause loose or protruding rocks to dislodge, leading to rock falls that can pose serious threats to workers in the vicinity. The unpredictable nature of these falls makes it essential for those working near highwalls to be vigilant and employ safety measures, such as proper barricading and regular inspections, to mitigate the risk. Recognizing the dangers associated with rock falls is crucial for ensuring a safe working environment in surface mining operations.
