Abstract
The effective distance between underground excavations (column width) was determined. The stressed and deformed state around the excavation and displacements of the excavation walls are determined. The technology and procedure of excavation and backfilling of the excavation during the construction of the protective cover are taken into account. Qualitative and quantitative evaluation of the results of numerical modeling was carried out. The finite element method was used as a method of analysis.
