The paper presents results of numerical modeling of the longwall gateroad floor heave in the Taldinskaya-Zapadnaya-2 mine. The research is conducted using the finite element method. The research has shown that the floor heave can be reduced when using the relieve slots which are cut in two areas. The reasons and the mechanism of a floor heave of entries are considered. Influence of the major geological and mining factors is revealed. Recommendations about decrease in heave in entries of coal mines are made.
