Rock heaving in underground mine workings is one of the most common types of rock pressure manifestation One of the conditions that cause heaving in development workings is the waterlogging of the workings and the high sensitivity of clayey rocks to softening. Mining operations cause viscoelastic deformations in the rocks, which intensity increases over time. A plastic deformation zone forms within this area, which also changes in size over time. The stress state of the rocks in various parts of the plastic deformation zone will be different, leading to different deformations. As the difference in the strength and plastic properties of the rock of the floor and the walls of the mine decreases, the nature of the deformation processes changes. When choosing a method to control heaving, the first step is to determine the need for additional measures. Based on the research conducted in actual mine conditions, this paper proposes measures to control heaving in mine workings.
