Development Height of the Water-Conducting Fractured Zone in Super-Wide Longwall Panel Mining of Medium-Depth Coal Seams
The development height of the water-conducting fractured zone (HWCFZ) serves as an important basis for the prevention of mine water disasters and assessment of water resource impacts. In recent years, with the increasing adoption of super-wide coal mining longwall panels with a width exceeding 300 m, studies on their H...
