Paper Summary

The researchers looked at how roofs in steep coal mines get damaged. They made a model to see how the roof breaks when it's under pressure. By studying stress and movement in the coal mine, they figured out how far the roof could break. Their work helps improve safety in coal mining by understanding how the roof can fail in deep, steep mines.
