Mathematical Modelining of Underworked Rock Strata Failure Process

摘要

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 Be-reznikovsky potassium mine has been done.
