Abstract: The urgency of the discussed issue: The influence of rate of face advance on the processes of earth surface’s subsidence is estimated ambiguous by different scientific investigators. 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 point’s displacements on profile line in the direction across the strike and rate of face advance and other impact parameters. 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 rear half of the mold the influence of face advance speed has not been revealed. In the front half of the mold increase of face advance rate reduces dynamic subsidence. Empirical relationships between subsidence of individual points on the undermined surface and positions of the working face are established.

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