摘要：
The physical and analytical modeling of coal discharge in thick coal mining by sublevel caving involves the method when coal is discharged under gravity on the powered support units and is proportioned-fed to a face conveyor placed between the support units. Based on the physical modeling, the authors put forward a mathematical model to study the gravity flow of granular material in three dimensional formulation using discrete elements.
