Failure Law of Soft and Hard Interlayer Overlying Rock in Gently Inclined, Super‐Thick Coal Seam and Research on the Development Height of a Water‐Conducting Fissure Zone

Failure Law of Soft and Hard Interlayer Overlying Rock in Gently Inclined, Super‐Thick Coal Seam and Research on the Development Height of a Water‐Conducting Fissure Zone

ABSTRACT This study examines the failure laws of soft and hard interlayer overlying rocks and the development height of the water‐conducting fracture zone in a gently inclined super‐thick coal seam at the Qifeng coal mine, Shanxi. The overlying rocks above the working face were classified into four...
