By the Discrete Element Method in a three-dimensional formulation, a numerical analysis of the areal coal discharge during the underground mining of thick flat coal seams using self-caving technology has been carried out. The kinematic flow patterns of mined rock depending on the number and location of the outlet openings are given, the zones of their mu-tual influence are determined. The change of coal extraction indicators depending on the num-ber of outlets and the distance between them are demonstrated.
