The emergency condition of the mine surface facilities including a coal wash plant, a crusher, a bunker and three galleries, is considered. As a result of a complex of engineering-geological and geophysical surveys, it is established that the significant deformations of the foundations of the structure are caused by the zones of weakened (unconsolidated) soil in the bases of the foundations formed due to landslide developments in the bulk ground mass. The article describes the techniques for justifying the technological parameters of the consolidation grouting of soil bases including computer modeling, forecasting of deformations of the natural and consolidated ground mass, analysis of the stress-strain state of soils in the most dangerous area. The effectiveness of the adopted scheme of consolidation grouting of soil bases according to the approved methodology for elimination of the emergency condition of the mine surface facility was confirmed. The limit values of the calculated horizontal deformations in the soil bases of one of the supports of the galleries are determined. To prevent the indicated deformations, it was recommended to provide an additional row of injection wells with a depth below the border of the loosened soil zone.
