Abstract

The mine workings and nearby structures and facilities form a single natural and technical system, the safety of which is a challenge due to the technological deformations that occur during mining operations. Progressive technologies are used to minimize these deformations, but nevertheless it is necessary to control the stress-strain state based on geotechnical monitoring data. The shape of the ground surface deformation trough in the area of mining works is considered. The results of analysis of experimental data on ground massif deformations in case of construction near the excavation being developed are investigated in detail. Analytical expressions for determining technological settlements at various designs of excavation support are given. Numerical values of technological settlements at various technologies of work production are specified.
