Abstract

The invention relates to the mining industry and can be used in the construction of artificial pillars from hardening mixtures in the developed space. The goal is to increase the reliability of work by speeding up the construction of an artificial pillar at the border of the supported production and mined space while improving interactions with lateral rocks. For this movement, the formwork includes front and side shields, made telescopic. The lower elements of the boards are rigidly connected with the formation of a U-shaped lining support formwork. The shields have upper elements connected by the upper part, which are the support of the hydraulic jack. Another hydraulic jack is located in the intermediate upper ke. In addition, the tops are connected to the base by hydraulic legs. In the formwork, there are hydraulic legs on a support connected by a hinge with a front shield. Between the last and the end of the pillar there is a cavity. For orientation of the longitudinal beam serves hydropotron. The formwork is equipped with a nozzle to fill the cavity. Simultaneously with the coal notch, the cavity is filled with a hardening mixture. After shifting the support sections, move the formwork in the direction of the zavalny part of the support. 10 il.
