    The invention relates to a shield structure particularly adapted for longwall mining providing a protected area that effectively insures operator safety even if total collapse of the mine roof should occur. The prop supporting the load-bearing cap of the shield is inclined rearwardly with respect to the mine face, and a pair of tension links that are pivotally connected to each other and are acted upon by a hydraulic cylinder in a direction transverse to the tension links, provide a structure which will ensure a widened (though shorter) protected area in which an operator may reside even upon complete roof collapse. The widening of the area helps insure that any fallen material from the roof will not harm an operator in the protected area.

    one
    The invention relates to the mining industry, namely, to mechanized crepes.
    According to main patent N 68364}, a mechanized roof support section is known that includes a base, a hinged fence connected to it, installed between a base and a hydrorack guard, a visor with an eye connected hingedly by means of an axle with a guard, top to, a hydraulic steering jack is attached to the fence while the hole in the eye of the visor is made spherical, the hydraulic control jack is connected to the top, and the top to the guard is pivotally connected with an axis, which is located 5 along the section and height at one level with a place of attachment of gidroeek to kozfku 1.
    This support improves the adaptability of the support to unevenness and increases the efficiency of maintaining a bare roof over the conveyor jO.
    The disadvantage of this support is that the workers move between the conveyor and the final depressions, which reduces the safety of work, because with an increase in the thickness of the reservoir, the mineral can penetrate into the wellbore space, leading to injuries. In addition, when the lining section is moved to the conveyor, the movement of workers along the lava is impeded. The movement of the workers between the hydraulics and the fence due to the small cross-section is also difficult.
    The purpose of the present invention is to increase the efficiency of the lining by simultaneously maintaining the bare roof above the conveyor n. convenient movement of workers along the lining.
    The goal is achieved by the fact that the base and the barrier are additionally interconnected by means of two tg connected by a hinge and an inlinder mounted to the hinge of the stockpile, mounted on the ground, on which the hydraulic post is tilted in the direction of the dam.
    FIG. 1 shows a mechanized support section, side view; in fig. 2 - section A-A of FIG. one; in fig. 3 - view B of FIG. one.

    Claims (3)
    [1]
    The mechanized fastening section contains a base 1, a swinging visor 2, top to 3, a fence 4, hydraulic racks 5, are installed between the base 1 and the fence 4. The peak 2 has an eyelet with a spherical hole and is connected to the fence 4, top 3, by means of axis 6, which is located along the bottom of the section and the height at the same level with the place of fastening of the girders 5 to the swinging one with the visor

    2. The fence 4 is divided into two parts, each of which is pivotally attached to the balancers using the axles 7. The balancers 8 are pivotally attached to the base 10 krositains 1 by means of the axles 9. One ton of ha is filled in the form of two plates 11 rigidly connected to each other sheet 12. One plate 11 is connected with axis 7 of one part of the fence, and the other plate 11 is connected with axis 7 with another part of the fence. The second t of ha is hinged by means of the axis 13 and the bracket to the base 1 and is also made of two plates 15 rigidly connected to each other by a sheet 16. Both of the hinges are hingedly connected to each other by an axis 17 to which the rod 18 of the hydraulic cylinder 19 attached is hinged. on axle 9. The hydraulic control jack 20 is installed on the side of the sill 5 and is connected to the barrier 4 and top
    [3]
    3. Sections of mechanized supports are installed in lava close to each other and side shields 21 and 22 of adjacent sections are in contact with each other. The side shield 22 is installed with the possibility of extension by means of a hydrodial of the shaft 23. The lining works as follows. When the working fluid is supplied to the piston cavity of the hydraulic cylinder 19, the shunt 18 extends AND moves the axis 17 along arrow C. The hydraulic post 5 is also moved apart, and due to arrically coupled t and hydraulic cylinder 19, the hinged fastening of the fence 4 from the base 1 is shifted to the side slap The hydraulics 5 are inclined towards the dam and the area between the hydraulics 5 and the throats is large enough to allow the worker to move freely along the lining. When reducing the thickness of the reservoir, the hydraulically reinforced 5 reduces and the barrier moves downward and shifts towards the dam, while the rod 18 moves into the cylinder, and the tractor connected to the base 1 and the axis 17 with another thrust also moves towards the dam. as a result, the vacant area for moving workers across the width increases. Claims of the Mechanized Support Section according to Patent No. 683641, characterized in that, in order to increase the efficiency of the support, by simultaneously maintaining the bare roof above the conveyor and facilitating the movement of workers along the support, the base and the fence are additionally interconnected by means of two t zannyh by means of the hinge and attached to the hinge of the rod of the hydraulic cylinder, mounted on the base, on which is fixed a hydraulic post with a slope in the dam. Sources of information taken into account in the examination 1. USSR patent N 683641, cl. E 21 O 23/00 ,. 1972 (prototype).
