Height of the Fractured Zone in Coal Mining under Extra-Thick Coal Seam Geological Conditions
The height of the fractured zone caused by coal mining is extremely significant for safely mining under water, water conservation, and gas treatment. At present, the common prediction methods of overburden fractured zone height are only applicable to thin and medium-thick coal seams, not suitable fo...
