FIELD: mining.
SUBSTANCE: invention relates to investigation of mechanical properties of rocks. Device for determining power consumption of destruction of rocks comprises bed, perforated barrel to accommodate testing rock samples, punch and loading hydraulic cylinder. At that, perforated barrel is installed relative to bed through thrust and radial bearings, and through spline joint is connected with handle for rotation of barrel.
EFFECT: technical result consists in simplifying the process of measurement of power consumption due to possibility of removal of fractions of broken rock by means of rotation of perforated barrel.
