ABSTRACT
Potash and salt deposit development is always associated with the risk of inrushes of fresh waters into stopes and mine flooding. This article considers experimental and theoretical approaches to mining safety and mine protection from flooding that are based on an informative interpretation using mathematical modelling results of instrumental and geophysical studies regarding mechanical properties and stress-strain state of undermined rock mass. A comprehensive implementation of these methods provides adequate mathematical modelling results and allows increased validity of predictive estimates related to stability of structural elements and integrity of water-blocking strata when it comes to the room-and-pillar method.
