Abstract
Approaches to mathematical modeling of waterproof strata stress-strain state modification under the influence of large-scale mining have been considered. The level of anthropogenic impact on waterproof strata (WPS) was controlled by realized parameters of movement trough. Mechanism of forming tensile and shearing cracks in waterproof strata has been determined. Retrospective numerical analysis of the reasons for WPS discontinuity at abnormal flood of the First Bereznikovsky potassium mine has been done.
