TEST BENCH FOR INVESTIGATING ENERGY EXCHANGE IN BLOCK ROCK MASSES Russian patent published in 2016 - IPC G01N3/10 

FIELD: test equipment.

SUBSTANCE: invention relates to test equipment, to devices for testing materials, particularly rock, when investigating energy exchange in block of rock masses in order to forecast and prevent dangerous dynamic phenomena. Test bench for investigating energy exchange in block of rock masses, comprising a support frame, arranged therein a sample clamp, a jack for movement of sample clamp, a clamp for a counter-sample and a jack for movement for counter-sample clamp perpendicular to direction of movement of sample clamp, according to invention, it is equipped with a second clamp for a second sample and a jack for movement of clamp of second sample along direction of movement of clamp for counter-sample, wherein sample clamps are configured for load application to end surfaces of respective samples, facing clamp for counter-sample, and clamp for counter-sample is configured for load application to end and side surfaces of counter-sample, facing corresponding sample clamps.

EFFECT: technical result is broader functional capabilities of stand by providing tests during interaction of both two, and three units with change in number of interacting units during experiment.
