Cooperative load‐bearing characteristics of a pillar group and a gob pile in partially caved areas at shallow depth

Abstract Stress concentration in partially caved goaf is the main cause of dynamic pressure accident in the lower seam mining. Aimed at the characteristics of caving in shallow partially caved goaf (PCG) and the specificity of interior load‐bearing structures, a classification criterion of goaf cavi...
