Abstract

The invention relates to the mining industry and reduces the laboriousness of the work and the cost of maintaining the mine working section (HS) between the paired lavas due to the use of linear sections (LS) of the mechanized support of the same size as in the downhole when unloading and shifting. Extraction pillar work out two paired lavas. The area of the GW between the lavas support LS 4 lining. They are installed in the HS from the side of the worked-out space one after another and connected with jacks. The first LS 5 is connected to the lining 6 of the conjugation. LAN 4 is installed on a rigid collapsible base (LRW) 7, which is placed throughout the entire area of the maintenance of HS. The height of LRW 7 H _{b is} determined by the formula H _b = H _c - H _max ^. 0.85, where H _in - the height of the GW in the light

H _max - the height of the drug at the maximum razdvizhnosti

0.85 - the safety factor of razdvizhnost The width of LRW 7 is taken to be equal to the width of the LS support. After shifting the support in the lava of the HP, the support is also successively moved one after the other along LRW 7. At the same time, the liberating part 8 of LRW 7 is transferred and placed in front of the front LS 4 to the position 9. Additionally, the LAN 4 is provided with load-bearing elements 10. 2 z. f-ly, 2 ill.

FIG. 2

the pole is practiced by two paired lavas, the section of the GV between the lavas supports the LS 4 lining. They are installed in the HW on the side of the developed space one after the other and are connected with jacks. The first LS 5 is connected to the lining 6 of the interface. LAN 4 is installed on a rigid folding base (LRW) 7, which is placed throughout the entire area of the maintenance of HS.

The purpose of the invention is to reduce the labor intensity of work and the cost of maintaining the section of mining output between paired lavas by using linear sections mechanized.

The method is carried out as follows.

The extraction column is processed by two paired lavas 1 and 2, and lava 1 is ahead of lava 2 by the value. section 3, which is necessary to maintain, as it is common to both lavas. For this purpose, conventional linear sections of mechanized roof supports are used, which are used in the clearing face, the fence is removed from them and installed directly in the preparatory excavation from the developed space one after the other and connected to the base or “overlap” with hydraulic jacks. They are equipped with 6 fixtures. The sections are mounted on a rigid collapsible base 7, laid on the soil throughout the whole area of supporting generation, the base height hg being determined by the formula

hЈ h6 where - the height of production in the light; LMO (K-height lining with maximum razdvizhnosti;

0.85 is the safety factor of expandability, and the width of the base is taken to be equal to the width of the support sections.

After the next shifting, lining in the lava of the section is also successively moved one after the other along the base 7, while the shifting can be performed with residual backwater. After moving the sections, the vacant part of the base 8 is transferred and placed in front of the front section in position 9.

In order to increase the stability of the mechanized support sections, when they are unloaded and shifted, they are supplied with additional supporting elements 10. Due to the fact that all sections, except for one being moved, are constantly in the open position, the unloaded section hangs on the supporting elements and moves along them by means of hydraulic jacks, otherwise all operations are repeated in the same sequence as for the support with the lower base.
