【 摘 要 】

The urgency of the problem of the occurrence of earth surface failures above underground excavations is substantiated. A model of a rock massif in the zone of a dip over a mine excavation has been developed. A new method for eliminating the failure of the earth's surface is proposed. The strength and deformation characteristics of the packing material used to eliminate the dip are investigated. Stresses and deformations in a soil massif are determined for various variants of layerwise deposition of materials into a dip. On the basis of full-scale observations of the development of failures and generalization of the results of their elimination, it has been established that the method of liquidating the failure has a significant effect on the nature of the work of the rock-lining structure being created. It is proved that the strength and deformation characteristics of the formed filling massif exert a significant influence on the stability and durability. The results of modeling the layer-by-layer method of liquidation of the dip confirmed its high reliability and efficiency.
