The emergency condition of a structure that is complex in plan of and located in the mine development zone. As a result of a complex of engineering-geological and geophysical surveys it was established that the cause of significant deformations of the foundations of the structure are the zones of weakened and water-saturated grounds at the base of the foundations, formed due to changes in the hydrogeological regime and man-made accidents. The technique of substantiation of technological parameters of the injection method to soil consolidation is described, including computer modeling, forecasting of deformations of the naturaland fixing massif, analysis of the stress-strain state of soils in the most dangerous area. The effectiveness of the adopted scheme of injecting reinforcement was confirmed according to the approved methodology for liquidation of an emergency condition of a mining structure. It is proposed to create additional fixed zones within the formed zone.
