Theoretical explanation of conditions for sinkholes after emergency flooding of potash mines

详细

The authors discuss conditions for sinkholes in the ground after the active phase of potash mine flooding has been completed. The mathematical modeling shows that interconnected signs of sinkholing are localization of subsidence in a comparatively small area, high gradients of subsidence at the boundaries of this area and occurrence of a solution cavity sufficient to accommodate the caved volume. The research findings are promising in terms of adequate space–time prediction of dynamic failure of strata above flooded mines.
