Deformation Behavior of Hard Roofs in Solid Backfill Coal Mining Using Physical Models

Solid backfill coal mining technology has been widely applied in coal seams that are at risk of hard roof. Using actual measured strain–stress curves of the backfill body and the similarity theory, this study designed and employed four experimental models for physical simulation, corresponding to ro...
