Abstract: The urgency of the discussed issue:A recent scientific investigations in the undermining area include dynamic phenomena and regularities of dynamicmoldformation which are depending on advance the face to the strike. The regularities of individual point’s displacements and the relationship between the vertical subsidence and horizontal displacements in the mold formation process have not been considered by most researchers. The main aim of the study: The study aims are revelation of the characteristic features of individual undermined surface point’s movements and establishment therelations between the vertical and horizontal point’s displacements in the direction across the strike, which are depending on advance the face to the strike. The methods used in the study:Patterns of individual point’s displacement of the undermined earth's surface are identified by frequency instrumental observations on the relevant lines. Further analysis is done by mathematical methods, including with the random numbers theory. The results:In the dynamic mold formation the regularity of individual point’ssubsidence troughhorizontaldisplacement across the strike is practically linear.The relation between the subsidence and horizontal displacement for undermined points depends on its position on the profile line.Empirical relations between subsidence and horizontal displacements for the points of the edge of the mold to the dip are given.

Key words: daylight surface undermine dynamic zone of displacement relation between subsidence and horizontal displacements advance the face to the strike regularity calculation
