(54) MECHANIZED STRESS STRIPPING

 . : .. v

The invention relates to the mining business, namely to mechanized fortifications, and can be used for mounting the drifts in the zone of their interface with lava, equipped with a mechanized complex.

Known Kpienb mates, including side and middle sections, interconnected by a hydraulic ram and a cross-section, which is mounted on the base of the middle section 1.

The disadvantages of this lining are the small value of the roof tightening factor, the impossibility of working with extracting the permanent lining of the drift in the condition of 1 x weak roofs and the impossibility of positioning the drift conveyor in the middle part of the lining.

The closest to the proposed one is the mechanized lining of the mating, comprising a middle section consisting of front and rear hydraulic posts with stabilizers, a top and a base in which the cross member is fixed on the longitudinal element, and the outer sections installed on both sides of the longitudinal element behind the cross member the bases of which are & nn are connected to the cross member by means of hydraulic jacks mounted on the outside of the girders 2. ,

The disadvantages of this support are poor adaptability to the varying width of the drift, difficulty moving the extreme sections in conditions of weak soils, because when loading the middle section the support plate (popetochina) rests on the ends of the extreme sections and presses them to the soil, as well as the impossibility of work without repayment drift. All this narrows the scope of lining.

The purpose of the invention is to expand the scope of application of mechanized support mating.

This goal is achieved by the fact that the crossbar has sliding elements with vertical axes for communication with the hydraulic jacks of movement and is fixed on the front end of the longitudinal element, which is made in the form of a groove with wider support

25 pads at the rear end for the rear hydraulic legs, with the front hydraulic legs mounted on the ends of the cross member.

Figure 1 shows the mating support, a general view; figure 2 - section

And-d in figure 1 in figure 3 - view B in figure 1

Mechanized lining mate consists of middle and extreme (left and right) sections.

The extreme left section consists of a base 1, on which hydroracks 2 with stabilizers 3 are installed, and the top 4, and the far right section is from the base 5, hydrorails b with stabilizers 7, and the top 8.

The longitudinal element 9 of the base section is made in the form of a gutter with widened pads 10 on the rear horse for installing rear hydraulic posts 11, Front hydraulic posts 12 with stabilizers are installed at the ends of the cross member 13, which is sattpenle at the front end of the longitudinal element 9 and has extendable elements 14 with vertical axles MI for communication with the hydraulic jacks 15 movement, mounted on the extreme bases. .

The tops 4 and 8 of the outermost sections, and the top of the middle section 16, can be interconnected by moving joints (for example, a tongue-and-groove connection).

Mechanized lining mating works as follows.

First, the middle section of the support is moved, for which its hydraulic legs 11 and 12 are unloaded and the hydraulic cylinders 15 are moved onto the {) slide, as a result of which the middle section moves forward a new step. During this period, the upper permanently supported drift lugs are held by the upper 4 and 8 of the outermost (left and right) support sections.

The outermost sections of the support may move simultaneously or alternately, for which purpose, to reduce their hydrocalls 2 and b, and the upper caps 4 and 8 move away from the road. Then, I turn on the hydraulic jacks 15 for movement, with which the outer sections are supported to the cross-member 13 of the base of the middle section. During this period, the top drift constant Clamps are supported by the top 16 of the Middle section of the mechanized roof support. After the shifting of the left and right sections is completed, thrust legs

2 and b, as a result of which the top of the permanent support drift is pressed to the roof.

Such an implementation of mechanized support mates allows placing either a conveyor in the channel or 5 Reloader, provides high lateral stability of the support, low specific pressure on the drift soil, the ability to work effectively in the presence of a drainage ditch, passed

About in the middle of the drift, to work behind it to maintain the drift for reuse, and also to place in its zalivny part of the transfer pump (in the case of water

5 for mating of lava with drift). All this expands the scope of application of the proposed lining and reduces the laboriousness of work in the zone of junction between the lava and the drift.
