DEVICE ESTABLISHING MECHANICAL CHARACTERISTICS OF ROCKS Russian patent published in 2003 - IPC

FIELD: mining industry, determination of mechanical characteristics of rocks, for instance, dumped rocks. SUBSTANCE: given device includes thrust beam, anchor piles, vertical and horizontal hydraulic jack, casing with balls, casing with rock, bearing members, guiding mechanism. Horizontal hydraulic jack is mounted on column for swinging. Guiding mechanism includes crank and link with swinging slider. Slider is mounted on frame and is coupled with one end to rod of horizontal hydraulic jack and with other end to tie-rod attached to casing with rock. Guiding mechanism secures horizontal motion of tie-rod and casing with rock. Bearing members come in the form of supporting masts anchored on frame and tied up with rope and anchors which are coupled to supporting masts by means of rope. EFFECT: proposed device makes it possible to establish parameters of strength and deformation properties of rocks reliably and efficiently, in mutually perpendicular directions included. 1 cl, 3 dwg
