Abstract

The invention relates to mining and m. used in the development of reservoir deposits by mechanized complexes. The purpose of the invention is to reduce the cost of installation of the complex. To this end, an emphasis is placed on the initial spreading of the lining sections and the spreading is carried out with the subsequent excavation of the mineral and the introduction of the complex under the roof of the formation. An emphasis is created with the help of ropes 1 and 2, located under the lining sections along the length of the complex along the lava and attached to the supports of the supports. Tensioning of the ropes is carried out by means of spreading of racks and a system of tackle 5. After shifting all sections of the support, tension is removed from the ropes 1 and 2 and moved them after the sections of the support. When leading the front pillars of the sections, the lining 1, which is closest to the face of the slab, is dismounted and pulled out onto the drift. When leading to the upper sections not less than 2/3 of its length, rope 2 is dismantled under the roof of the formation. The method significantly reduces the time required for the complex to exit the assembly chamber. 3 il. (Ls

The invention relates to mining and can be used in the development of stratum deposits by mechanized complexes.

The purpose of the invention is to reduce the cost of installation of the complex.

FIG. 1 shows the arrangement of mechanized support in the mounting chamber, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the position of the lining sections in the process of their entry under the roof of the reservoir, side view.

After mounting the lining sections, for example, used ropes 1 and 2 on the trunks (the number of ropes may be two or more) are mounted on the trunks of the lining with the help of a winch, after which their ends are fixed on the supports of the mates 3 and 4 . Tensioning of the ropes 1 and 2 is carried out with the help of the sling of the polyspaths 5 and the hydroelements 6 and 7 of the supports of the mates. At the same time, at one of the interfaces, for example, a ventilation drift with a mounting chamber, the hydraulic legs 6 of the supports of the interfaces fully extend between the roof and the working soil, and when coupled with the conveyor roads for expansion of the hydraulic supports 7 of the interfaces, if necessary, to the top and sections The mates lay out, for example, wooden fires or wooden chocks (not shown), thereby ensuring the necessary tension of the ropes. A mechanized complex is then introduced under the roof of the formation, i.e. alternately shifting the lining sections.

Following the passage of the shearer and the excavation of the first strip of the mineral, approximately 6-10 sections of the lining are supported between the soil of the assembly chamber and the tensioned ropes 1 and 2. In these sections, advances are made and the conveyor 8 is pushed towards the clearing face 9. After that, the tops lining sections are lowered, i.e. remove sections from thrust. Specified

The cycle is repeated until the full slide of the downhole conveyor 8 is completed along the entire length of the lava. Then, remove the thrust from the support sections, turn on the jacks of the shifter 10, the sections are tightened along the entire length to the bottomhole conveyor 8. After moving all the sections of the mechanized assembly, remove the thrust from the support sections, move them along the roadway, tear them apart ropes 1 and 2 are twisting.

After the second mineral strip has been excavated, the process of moving the mechanized complex is repeated. When leading the front gidroek sections lining (Fig. 36) under the roof of the reservoir, the cable 1 closest to the face is dismantled they are detached from the supports and pulled out onto a conveyor or ventilation drift using a winch. When leading the upper lining of sections not less than 2/3 of its length, the next cable 2 is dismantled under the roof of the formation (Fig. 3c).
