Abstract

The invention relates to the mining industry and m. B. used in underground mining of mineral deposits with hardening laying of the worked-out space and a downward layer excavation. The goal is to reduce the flow rate in the tidal due to the uniform laying and sealing of the hardening mixture. The device for strengthening the layers of backfill material includes a flexible metal overlap 11, an insulating jumper 10, and transverse elements of reinforcing bars 1 installed in the form of pyramids. On the latter, longitudinal reinforcing elements are located with the possibility of reciprocating oscillations. They are made in the form of exhaust pipelines 2 with windows 3. The exhaust pipes 2 are rigidly connected to the distribution pipe 4 and have a smaller diameter. The distribution pipe 4 is connected to a backfill pipe 7 with a connecting pipe having a mixture switch 9 and is located behind the jumper 10 parallel to it. Through the filling pipe 7, the hardening mixture flows into the distribution pipe 4, which oscillates by means of a vibrator. The hardening mixture then flows into the exhaust pipes 2 and, due to their reciprocating vibrations, is stirred and, through the windows 3, is poured onto the production soil in an even layer. 2 Il.

The invention relates to the mining industry and can be used in the underground mining of mineral deposits with a hardening mortgage of the developed space and a downward layer excavation.

The aim of the invention is to reduce the flow rate in the twitch due to uniform styling and compaction of the hardening mixture.

FIG. I presents a submerged portion of deposits, a vertical section; in fig. 2 - the same, top view.

The device for hardening the layers of the backfill array consists of transverse elements 1 of reinforcing rods installed in the form of pyramids, longitudinal elements in the form of exhaust pipes 2 with windows 3 along their entire length, distribution pipe 4 of increased diameter with the vibrator motor 5 installed on it air motor b, backfill 7 and connecting 8 pipelines, switch 9, insulating jumpers 10, flexible metal ceiling 11.

In the spent, but not yet laid, layer 12, a flexible overlap 11 is placed on the soil, on which transverse elements of reinforcing rods are installed, the lower ends of the rods are connected to the flexible metal overlap 11, and the upper ones are designed in such a way that they lay longitudinal elements in the form of exhaust pipes 2 with windows 3, wherein the distance between the windows is assumed to be equal to the distance between the transverse elements and does not exceed the distance between the longitudinal elements. The ends of the pipes 2 are taken out of the insulating jumper 10 and rigidly and hydraulically connected to the distribution pipe 4 of increased diameter located behind the insulating jumper 10, parallel to the latter, on the pipe 4 mounted on shock absorbers 13, the motor-vibrator 5 and air motor 6 are strengthened, the pipe 4 is fitted a plug with a valve 14 for draining the water during flushing, and on the other hand a connecting pipe 8 leading from the main pipeline through a switch 9 is connected to it.

The device works as follows.

The developed space prepared with the tab with the mounted device for strengthening the layers of the backfill array is fed from the surface with a hardening mixture with a standard content of a mortar. The hardening mixture, passing through the pipeline 7, through the switch 9 enters the distribution pipe 4 of increased diameter, while in the pipe 4, which makes longitudinal oscillations under the influence of a vibrator, the vibrating grains are vibrated and the mixture is additionally mixed during transportation. Next, the hardening mixture enters the exhaust pipes 2 connected to the pipe 4 and performs longitudinal reciprocating synchronous oscillations, and the mixture is agitated, after which it is poured onto the working soil through the windows 3 in an even layer.

0 The next stage of vibroactivation of the mixture is the transfer of vibration of the laid mixture from the vibrating motor 5 through the system of pipelines and transverse elements 1. After the layer reaches a level, the power equal to the height of the transverse elements 1 of the reinforcing rods. The process of vibroactivation is stopped and with the help of a winch 15 the piping system, consisting of a distribution pipe 4 of increased diameter and exhaust piping 2, is extracted for repeated use. Thus, form the lower carrier layer of the artificial array 16.

After the process of vibroactivation of the artificial layer of the artificial array is completed, the piping system is removed, and the filling pipeline is switched to supplying the remaining solid content of the hardening mixture to the remaining unfilled part of the quenched space.
