The article discusses how mining can affect water conductivity in coal roofs, which is important for underground mining safety. By studying damage to rock mass caused by mining in different areas, researchers found that water inrush risk depends on water in old mining areas. They developed a model to predict water conductivity changes in lower coal seams, helping to make safer mining decisions.
