The Hydrodynamic Regime of Groundwaters in Coal and Oil-Shale Mining Leases

The data on the underworking of water objects and piezometric surveys have allowed scientists to reveal a correlation between hydrodynamic conditions in groundwaters and the stressed and strained state of rock masses at the sites of underground mining of coal and oil-shale deposits. The hydraulic fracturing of the downward filtration current within the layers of clay rocks and upon their contact with sand- and limestone layers was found, along with a discontinuous distribution of hydrostatic pressure in the section of the water-conducting subsidence cracks resulting in groundwater accumulation on clay layers.
