The known solutions of the lining of the corridor and chamber workings described in the draft patent applications P-248566 and P-266854 have a bloated shape that is difficult to be practically produced, directly in the face of the workpiece. The methods of making these supports are based on drilling the slug in the first stage in the initial support and then its reconstruction. The solution of the casing structure itself is very labor-intensive in assembly and the insertion of bends with high accuracy in terms of bending radius and length. A significant disadvantage of these solutions is also the long resistance of the lining to side loads, which are particularly high in difficult mining and geological directions. The purpose of the invention is the casing and its method, while the casing structure will have limited susceptibility and increased resistance to side loads, and its accuracy will be ensured in the rantage phase in the mining excavation. 156 560 The method of the casing will make it possible to place the casing directly in the excavation as the final casing with the possibility of a delayed line in the rest of its part without loss of accuracy in the assembly of its elements ensuring proper operation and full of high endurance parameters of the material of the casing. This goal was achieved by the use of the casing structure consisting of double trough profiles made in the ceiling and floor as double, and at the height of part of the side walls as triple, where the double stoop arches are placed on the external side arches, to which the lateral arches in the wall are attached. with floor arches confusing the entire structure of the housing. The method of the support of the support is based on the assembly of the floor-side part with the possibility of full adjustment of the support compliance sections. The essence of the invention consists in the construction of the casing, in which the double roof arches, which at their ends are single and have external side arches, are fixed on the outside, so that there is a possibility of their mutual displacement. The external side bend is in turn attached to the internal side bend with their single end, which then connect as double with a single end to the floor bend. The method of execution allows for independent assembly in the excavation of the roof-side arch and the floor-side part of the casing, with the possibility of adjusting the length of the compliance section of the side arches, also with floor arches, by changing the position of one of the arches constituting an element of the double internal side arch. The solution according to the invention in an embodiment is shown in the drawing, where Fig. 1 shows the structure of the open casing, and Fig. 2 shows the structure of the closed casing. The roof arches consist of an outer arch 1 and a bend 2, one of which is single at both ends with the length of the designed overlap c and compliance A. The roof arches are bolted with locks 3, external side arch 4, placed on the foundation footing 5. The closure of the casing structure is made by means of three double arches, each of which is single at its ends along the length of the c and designed compliance Δ. The arches of the floor and rib part are connected with the floor and rib part in such a way that the interior side arch 6 is twisted with the external side arch 4 at a distance Δ from the end of the cone arch 2 by means of locks 3. The interior side arch 6 with its single end is connected to the floor arch 7 along the overlap length c ^. UpodaariLeiie of the casing structure in the bottom part to obtain equal sections of compliance Δ on the outer ring and νβ-ϋ ^ ΓΖnym is obtained by such fastening of the central side bend 8 during the assembly of the casing that after stiffening the casing, the internal and external bends adhere tightly to each other. forming two support rings. The support in the side part of the excavation has three arches, which significantly increase its load-bearing capacity. The side arches 6, 8 and 4 are joined together with a layer of building material 9, which is filled with whom they have formed. The contraction of a flexible-rigid steel support frame has a number of favorable properties, which are particularly important in difficult mining and geological conditions. The casing is composed of a small number of elements which, even with differences in the size of the radii and the length of the arches, allow the casing structure to be confused, which after folding and stiffening at the joints in each cross-section consists of double trough profiles, and three sections of trough profiles. The method of making the excavation carried out in two phases allows the use of a rock cutter with a combine, as well as allows the bottom of the excavation to be closed with a defined delay, allowing the bottom rocks to relax and to balance the load acting on the support. The structure of the casing can be circular, elliptical or other oval shaped, closed, adapted to various mining and geological conditions. 156 560 The casing and the method of erecting the casing are particularly useful for corridor and access chamber workings. In particular, the solution should be used in shaft inlets, exhaust chambers, chambers above and below the equalizing tank, water galleries of vases with reinforced concrete linings and concrete on floor hatches and other workings involving supports with high resistance with simple and fast wTcmnia technology. A simple solution of the structure of the support and the method of its implementation will allow it to be used to connect horizontal corridor workings with vertical workings by independently selecting the floor-side part of the excavation and placing it on the table beams or the frame of the edgewood arches. This solution allows to arrange the frame or supporting beams in the excavation, regardless of the casing of the ceiling and wall part. Thus, I do not have to make a preliminary casing with large dimensions ensuring the execution of the final casing.
