FIELD: mining.
SUBSTANCE: submersible metre of rock strength comprises a hydraulic cylinder with three concentric cavities: input, circular and discharge ones, a loading piston with a stem equipped with an indentor, and an additional rodless piston. At the same time between the circular cavity under the additional rodless piston and the discharge cavity of the loading piston with the stem there is a hydraulic connection arranged by means of a channel.
EFFECT: simplified design and expansion of functional capabilities.
