SU541999A1 - Section of mine mechanized lining - Google Patents

Description

The invention relates to motorized mechanized fasteners, in particular to their section

U {NM

The section of mine mechanized lining is well-known, which contains a scoop of single skirp, retractable supports, downhole landing gear stands and bottom hearth jacks.

A disadvantage of the well-known lining section is that it does not provide for the movement of pa in areas that are not fractured;

The purpose of the invention is to ensure the work of the lining with pillars by the fall in the seams with a broken integrity.

This, p.l., is achieved by the fact that, in the proposed section of the mounting section, the sections are made with directional grooves and windows, with the rods of one bottomhole stand-up skabzh & palzunami which are inserted into the 1-directional grooves, and in the windows are located; e support connected to the rods of the other downhole gidrometoiki.

Po.tzun can be equipped with an extension arm and retractable support brackets that

connected to the lugs through the fingers.

In order to prevent continuous mixing, it is advisable to attach a retainer to the cylinders of the downhole girders.

On o / ig. 1 shows the proposed mine mechanized lining section; in fig. 2 is a section along the line A-A in FIG. one; FIG. 3 is a section along L-b in FIG. one; in fig. 4 - the position of the elements of the section during the transition of the ledge.
