The study used a computer method to look at how mining affects the rocks above and below. They found that as mining happens, stress builds up above the work area, causing rocks to separate. When mining reaches the same spot as a pillar left from a previous mine, the pillar gets the most pressure. This can lead to big cracks in the rocks above and a lot of ground sinking. To prevent problems like rock bursts and sinking ground, certain actions can be taken.
