The paper describes the methodology of solving the problem of determining the degree of mutual influence of mining works on different horizons during the development of reserves of mine fields. By the example of mining three horizons of Starobinskoye deposit, the results of solving mining-geomechanical problems on the assessment of the stress-strain state (SSS) in the zones of influence of mined-out spaces of the salt massif are presented. The dependences for calculating the stress concentration coefficient at different configurations of the front of the development of mining works are proposed.
