Abstract.

The article presents the results of research on the development of new methods for controlling the floor swelling in the mine workings. It is shown, that the existing methods for controlling the floor swelling depending on various geological conditions are only partially realized, and their efficiency is low. For the purpose of establishing the dominant factors, which would decrease the floor swelling, the newly developed methods were simulated with the help of method of finite elements, and the results were compared. Special software was developed, which estimated different scenarios of geomechanical processes dynamics with taking into account the particularities of geological environment deformations and different ways of supporting the mine workings. The established parameters of the rocks allowed validating advantages of the new methods for controlling the floor swelling with the help of support setting technologies which use the steel-polymer anchors.
