Abstract
The results of numerical modeling of rheological processes both in the potash rock mass in the vicinity of an underground loading complex and in the lining of an underground structure are presented. An algorithm is proposed for solving the problems of calculating the durability of large-scale underground structures with an insufficient amount of initial data on the rheological properties of lining materials for underground structures and the enclosing rock mass. It is shown that even in such conditions, it is possible to qualitatively assess their geomechanical state in the long term. Comparison of various approaches to modeling rheological processes is made.
