On the example of the construction of the dismantling chamber No. 1 of the Kalinin-Solntsevskaya line of Moscow Metro, and the studies of the stress-strain states of the contour massif of rocks in the bottom zone by the finite element method, evaluating measures were taken to ensure the stability of the enclosing rocks and the camera’s protective screen. Simulation of the rock mass stress state has proved the possibility of soil hardening in the set of workings by advanced anchoring to reduce rock displacements and surface deformation. A model to determine the maximum depth of using a protective screen with long anchors has been compiled.
