Abstract
A dependence of Proterozoic clays in the faces of tunnels under construction from different factors affecting them, i.e. the depth of the seam, thickness of clays up to the Quaternary sediments, prognostic properties of rocks and tunnels diameter is analysed. Indexes of exposed rocks stability in different schemes of rock deformation are offered. The mentioned indexes can be recommended for underground surveying when forecasting surface deformation in underground construction works.
