Abstract

A mechanized support unit serving to maintain the gallery in a safe operational condition during underground mining works, comprises a prop (1) hingedly mounted between a cap (2) and a shoe (3), and a device (4) for compensation of the prop list, including a main correcting hydraulic cylinder (5) presetting the position of the prop (1) at the beginning of each technological cycle, an additional correcting hydraulic cylinder (6) ajusting the position of the prop (1) at any n<sth>s cycle, and a means (11) for calculation of a mathematical expectation of the list of the prop after n cycles, connected with its input to the prop (1) and with its output, through a valve (12), to the additional correcting hydraulic cylinder (6), its casing (7) being fixed to a base, in relation to which the position of the prop (1) is preset, and its rod (9) being hingedly connected to the casing (8) of the main correcting hydraulic cylinder (5) which is translatively movable in relation to the casing (7) of the additional correcting hydraulic cylinder (6).
