Abstract
The authors perform 3D discrete element modeling of pre-broken coal and dirt discharge in underground mining with sublevel caving of thick coal seams. The process of force interaction between rocks and powered roof support is analyzed. The difference between the discharge regimes with feeders equipped with smooth and corrugated surfaces is demonstrated. The mass flow of coal during discharge is shown.
