Abstract

The article presents the rationale of temporary supports used in the drilling of new mines, which provides for the construction of model projects of reconstruction of old tunnels. Finite-element method analyzed the changes of stress-strain state containing tunnel complex array during the drilling of new mines. Based on the analysis, a number of findings to explore the possibility of reducing the thickness of the permanent support of new mines in tunnel complex - the new tunnel, and transport and drainage culvert.
