The development of underground space has a negative impact on the state of objects on the surface. The search of effective ways to prevent deformation of the soil mass has not lost its relevance. The study focuses on advanced anchoring. Based on the analysis of the technological and structural solutions for the construction of the dismantling chamber No. 1 of the Kalininsko-Solntsevskaya line of the Moscow Metro, and studies of stress-strain states of the marginal rock mass in the bottom hole zone by using the finite element method, the measures to ensure the stability of the surrounding rocks and the protective screen of the chamber were considered. The simulation of the stress state of the rock massif shows the weaknesses in the operation of the structures, so the solutions for reducing the surface shrinkage during hardening of the array by advanced anchoring were proposed.
