Development pressure on rock massif is increased during the involving of many horizons of Starobinsky deposit into mining, which is expressed in waterproof properties of this massif. Nowadays, physical modeling of the researched process is carried out for estimation of possible consequences of repeated underworkings. Mechanisms of destruction of rock salt layers and formation of cross fractures in these layers are researched by bend tests of samples, according to the developed load programs in laboratory conditions. Mining of research methodology was carried out on the first stage. Usage of physical modeling for assessment of status of protection waterproof ceiling allows to make a conclusion about the possibility of accounting of layers' mining sequence in the methodology of calculation of spreading height of anthropogenic water supply fissures.
