Vynohradov Y. Development of a method for reducing water inflow and increasing the stability of mine workings in difficult hydrogeological conditions

Thesis for the degree of candidate of technical sciences in specialty 05.15.09 - "Geotechnical and mining mechanics". - Institute of Physics of Mining Processes, National Academy of Sciences of Ukraine, Dnipropetrovsk, 2018. The thesis is devoted to the solution of the current scientific and applied problem of reducing water inflow and increasing the stability of mine workings in complex hydrogeological conditions. To solve this problem mathematical models of the steady and unsteady water filtration in mining work for the underworking of watered rocks were developed taking into account the change in the permeability of contour rocks, depending on their stress-strain state. A method of reducing water inflow using anchoring is developed. The idea of this method is to create around the mine working an impervious rock-anchor layer. The developed method was successfully applied at the coal mines during the crossing of the high-amplitude dislocation. The water inflow in the danger zone is completely prevented.
