Annotation:

The results of analysis of Earth surface points' displacement trajectories above a moving coalface are described in the article. The numeral quantities of horizontal and vertical residual displacement of the profile lines benchmarks installed above the coalface of Western Donbas mines are presented. The presence of horizontal displacements of Earth surface points in the flat bottom of trough is confirmed.
