Analysis of Secondary Fracture Law of Roof Strata and Water Inrush Potential in Close-Distance Coal Seam Mining
Close-distance multi-seam mining frequently induces secondary surface deformation and subsidence. Extracting a lower coal seam beneath an existing goaf repeatedly disturbs the overburden, often leading to roof collapse and the expansion of vertical water-conducting fractures that connect the working...
