    The invention relates to devices that enclose the space from the penetration of the filling material, and can be used in the development of coal seams with the laying of the goaf.
    The purpose of the invention is to reduce the labor intensity and reduce the time to build a jumper.
    Figure 1 shows the end of the backfill jumper, side view; figure 2 is a fragment of the jumper, front view.
    A backfill lintel for filling a work bookmark consists of an openwork bearing structure 1, made in a grid pattern with square cells with a cell side equal to 0.5-1.0 m, worn out scraper conveyor chains or steel profiles with corresponding bending strength . This structure is detachably attached from above to the upper chambers 2, and from the bottom to the lying 3 mechanized supports. 8, the structure of the jumper also includes containers 4 with filter cloth 5, rigidly mounted on the shoulders 6 rear tops 2 of each set of powered support. The width of the container corresponds to the width of the filter cloth 5. In addition, above each container 4, on the back top 2, there is a fixed guide roller and a casing 8 protecting the container from the side of the filled production space,
    The casing is simultaneously used as a guide for the filter cloth 5 extending from the guide roller 7.
    The filling of lava workings according to the invention is carried out as follows.
    After the next development of a part of the coal pillar, individual sets of power support are moved to a new workplace. Together with the kits, the supporting structure 1 of the stowing bridge is attached to them.
    During the movement, the strip of filter cloth 5, which is located in the container 4, attached to this set of supports, is automatically unwound. In this case, the backfill fabric, laid on the basis of production, is held by a hydraulic bookmark. The filter fabric is wound in the container with a bookmark on both sides approximately 0.4 m. After unwinding from the coyteyner, a tab of 0.1-0.3 m wide is obtained when the strips of fabric join.
    After moving all sets of lining to a new workplace, separate bands of filter cloth 5 are connected
    between themselves along vertical lines so as to form a continuous partition protecting the working area of the lava from penetration of the hydraulic laying into it.
    Filling of the developed space can be carried out after each next development of the angle or after several developments and movement of the mechanized support for a certain
    distance

    The invention of the backfill liner to fill the bookmark workings, fixed
    mechanized lining, including an openwork supporting structure in the form of a grid with square cells, one end attached to the rear ends of the upper mechanized lining, and the other to its base, connected to the upper hydroracks, rigidly fixed on the shoulders of each upper container with strips of filtering fabric, which is laid on the grid of the supporting structure, covers, rigidly fixed on the rear ends of the tops above the containers to protect them from the side of the pledged space; made with guides for filtering fabric, characterized in that, in order to reduce labor intensity and reduce time for its
    erection, it is equipped with guide rollers, each of which is rigidly fixed on the rear end of the top over the container and on which the strips are laid
    filter fabric, while the carrier mesh is made of longitudinally and transversely located chains, and the side of the cell carrier mesh is from 0.5 to 1.0 m.
