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

open access: yesEnergy Science &Engineering, EarlyView.
Based on the layered structural characteristics of the strata, this study summarizes four typical overburden structural types under the geological conditions of the 51408 working face. Through theoretical derivation and numerical simulation, the study reveals the stepwise failure characteristics of the overburden and analyzes the variations in ...
