The data were obtained by numerical modelling of coupled processes of elastoplastic deformation of the coal seam and water and gas flow during hydraulic extrusion. For the considered computational case, the water injection pressure was 40 MPa. The dataset consists of two tables. The first contains the dependence of water inflow into the mine working on the time step. The second contains distributions of face displacement along its width at different time steps. The data allow Figures 9 and 10 to be reproduced and enable quantitative analysis of the filtration and deformation responses during hydraulic extrusion.National Academy of Sciences of Ukraine
