Forecast and Management of the State of the Mountain Range

This article discusses the safety issues of geomechanical processes in the joint development of oil and potassium salts. The problem is solved by the finite element method. To predict changes in the stress-strain state of a rock mass in the mining area, a method has been developed for calculating the values of rock deflection and reference pressure. On the territory of the Berezniki and Solikamsk districts there are huge areas and valuable salt deposits, and under them - oil fields of industrial importance. Such joint development is unique, and geomechanical processes in this matter are poorly understood. To ensure the safety of mining operations, as well as the safety of ground structures in these conditions, it is necessary to know the stress-strain state of the rock massif and the nature of the manifestation of the movement process during the joint development of oil and potash deposits. Over the ever-increasing excavation space, there is a deflection of rock layers with subsequent subsidence, which both positively and negatively affects the technological processes of production. © 2022 Institute of Physics Publishing.
