Question

Quizplus · Accepted Answer

Removal of large amounts of overburden material can cause the underlying earth materials to expand, which can lead to decreases in strength. This is because the removal of the overburden can release pressure on the underlying materials and cause them to expand or even fracture. This can result in settlement or instability, which can lead to safety concerns in construction or mining operations.
