   GNSS method was selected as the most suitable one for monitoring the surface after-effects from undermining in the Gabriela locality in the Karviná region. An observation network was built, whose points were repeatedly surveyed by this method. Evaluation of the obtained spatial coordinates allows analyzing not only the vertical movement, subsidence, as usual, but also the horizontal movement, horizontal displacement. This comprehensive approach would allow a better evaluation of the character of the creating subsidence depression. The extraction of the mining panel caused sizable surface changes in a short time due to a significant exploited thickness of the mining panel together with considerable failure of the overlaying strata from previous exploitations. The analysis of subsidence and horizontal displacement proved that the subsidence depression is creating in a symmetric way and the current centre of the subsidence depression is created above the exploited part of the mining panel
