Abstract: The urgency of the discussed issue: The regularities of individual point’s displacements in the mold formation process have not been considered by most researchers. This phenomenon indicates insufficient level of knowledge in this area. The main aim of the study: The study aim is establishment the relations between the vertical and horizontal point’s displacements on profile line along 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: Empirical relationships between the vertical subsidence and horizontal displacements of individual points on the undermined surface are established.These studies are based on previously achieved results will help predict the development of subsidence and horizontal displacement of individual points in the dynamics (depending on the position of the working face to the mounting chamber).The influence of rate of face advanceis taken into account.

Key words: daylight surface undermining dynamic zone of displacement subsidence horizontal displacements rate of face advance regularity calculation
