Abstract: The analysis of researches about face run influences on the process of mold formation is carried out. One of main mold parameters is the maximum subsidence. All kinds of displacements and deformations depend on this option. The regularities of maximum subsidence value and the displacements of the point of maximum subsidence relative to the mounting chamber in a developing displacement zone are revealed. To evaluate these parameters the functional dependencies based on trigonometric functions are proposed. The features of point movements on the earth’s surface in the plane of vertical and horizontal displacements during the molding formation by processing high-speed stoping faces in Kuzbass is considered. Four zones of displacements are allocated by characteristic features of movement of daylight surface’s points and their sizes are determined. To determinate of functional dependences between vertical and horizontal displacements in the allocated zones the generalized methodical data are given.

Key words: daylight surface high-speed breakage (stoping) face undermine dynamic zone of displacement subsidence and horizontal displacements and deformations regularity distribution function calculation
