The winter and spring seasons pose the most danger for surface mining due to the cycle of freezing and thawing. This is primarily because during winter, temperatures drop significantly, leading to freezing of moisture in the soil and rock. When spring arrives, temperatures rise, causing that moisture to thaw. This repeated cycle can significantly affect the integrity of the ground and the stability of the mining site.

The thawing process can lead to increased water content in the soil, which can reduce the soil’s load-bearing capacity, potentially resulting in landslides or ground failure. Additionally, the combination of thawing and freeze-thaw cycles can cause cracks and erosion, further destabilizing the area.

Understanding this seasonal vulnerability is crucial for planning and operational safety in surface mining operations, highlighting the need for thorough risk assessments and protective measures during these times.
