FIELD: mining.
SUBSTANCE: device for method realisation is installed into a well. The well is filled with dispersed material. Three parallel axes of well plane are set, and normal stresses to them are determined, using which, distribution of tangential stresses is detected in the perpendicular axis of the well plane. The device to assess the stressed condition of rocks comprises a pipe and a measurement system with a recorder. The measurement system is installed on the outer surface of the pipe and is made of three force sensors. Force sensors are arranged so that compression forces are measured in three set planes parallel to the pipe axis.
EFFECT: increased efficiency of the method due to control of tangential stresses distribution in the required plane and the device due to measurement of compression forces via a single well in three set planes that are parallel to the axis.
