Evolution characteristics of overburden structure in inclined fully mechanized caving under residual coal pillars of the upper layer

In the stratified fully mechanized caving of ultra-thick coal seams, the inclined layout of upper and lower caving faces leads to lower fully mechanized caving face intermittently crossing residual coal pillars of the upper layer. This results in complex overburden breakage and mine pressure behavio...
