The researches in the area of undermined rock massifs estimate the influence of advancing speed of mining stopes on earth’s surface shift-ing ambiguously. It reflects the lack of maturity of this trend. The aim of this paper is to establish the relationship between subsidence of individual points on the surface profile line along strike and the speed of stope’s advancing, taking into account other influencing factors. Dependencies of displacement of certain points of the earth’s surface undermined during mining operations can be identified by frequency instrumental observations on the profile lines. Further analysis is made by mathematical methods, in-cluding the random number theory. In the formation of the dynamic downfold of displacement the relationship between advancing speed and subsiding of individual points in the “behind the face” half-downfold can-not be traced. In the “front face” half-downfold the increase of mining stope advancing speed reduces dynamic subsidence. In the paper empirical relationships between subsidence of individual points on the surface and the position of the working face were shown.
