“…Immediate closure of such cavities may have unfavorable side effects, since such cavities are filled with burnt rock without identifying the causes of cavitation. This causes cavities to re-emerge, especially when openings are flooded [14][15][16][17]. This is why substantiating the parameters of the cavity closure method is a relevant scientific problem.…”

The purpose of the study is to study mining and environmental emergencies associated with the formation of sinkholes of the earth’s surface over mining workings after the mass closure of coal mines and to develop a new method for eliminating the sinkhole. The study used a method of physical modeling, which investigated the influence of humidity on the deformation properties of burnt rocks used as a filler in the manufacture of plugging and filling suspensions, while establishing the dependence of the relative deformation of dump rocks on the load at their natural humidity and water saturation. The main results of the research are: a new method for eliminating dips in the earth’s surface over the inclined opening workings of the liquidated coal mines of the Eastern Donbass; formulations of plugging and filling suspensions used for layer-by-layer filling of sinkholes and providing non-shrink laying.
