This study reveals the temporal and spatial evolution law of roof separation under the karst aquifer and the dynamic water inrush mechanism of roof separation. The FAHP–EWM–CRITIC combination weighting method was established to obtain the risk zoning of bed separation water inrush in a karst landform mining area. ABSTRACT Coalfields in northern Guizhou

A novel collaborative control technology of gob‐side entry retention with narrow roadside filling wall is proposed, wherein anchoring end of anchor cable must penetrate the boundary line of stress peak (plastic zone). ABSTRACT Gob‐side entry retention represents a major technological innovation in the history of coal mining, offering numerous ...

Based on theoretical analysis, the energy‐evolution behavior of the surrounding rock at various depths on the solid‐coal side of the 221303 material roadway during the “advancing‐toward‐mining” process was first clarified. Numerical simulations were then performed to validate and elaborate on the theoretical results.
