Abstract

The invention relates to the development of mineral deposits by the underground method with the laying of the goaf. The purpose of the invention is to increase the completeness of filling the developed space of the filling mixture. The stowing pipe consists of a horizontal rod 2 with nozzles 5 and 6. They are fixed crosswise around the circumference of the rod 2 and have a variable diameter increasing towards the free end of the rod 2, i.e. in the direction of expiration of the mixture along the pipeline This ensures a uniform flow of the mixture over the entire volume of the chamber. The upper nozzles are made with different lengths. The stowing mixture enters by becoming 2, then to the lower, side and upper connections, ensuring the filling of the entire chamber 1. 3 sludge.

The invention relates to the development of mineral deposits that are found by the underground method with the laying of the goaf.

The aim of the invention is to increase the completeness of filling the goaf with the filling mixture.

FIG. 1 and 2 schematically shows the filling pipeline; in fig. 3 shows section A-A in FIG. 2

The stowing pipe for laying the worked-out space of chamber 1 consists of horizontal pivot 2, frame 4, crosswise located around the circumference of station 2, which are separated from each other by a distance corresponding to the angle of spread characteristic of the mixture used. Boxes 4 are made in the form of nozzles 5 and 6, and the length and orientation of the nozzles 6 correspond to the roof configuration 3. In addition, the diameter of the nozzles 5 and 6 is variable, increasing with the flow direction of the mixture along the length of the pipeline for its uniform distribution throughout the chamber.

The stowing pipe operates as follows.

The filling mixture is fed into the developed space of chamber 1 in a horizontal position 2, centered in chamber 1 in the roof 3, through crosswise arranged circumferentially of the installation of 2 branch pipes 5 and 6, located at a distance from each other, corresponding to the spreading angle of the filling mixture used.

Moreover, the length and orientation of the upper pipes corresponds to the configuration of the roof 3. The diameter of the pipes 5 and 6 is variable, with an increase in its direction of movement of the mixture to distribute it evenly throughout the entire volume of the chamber 1. The backfill mixture entering into stand 2 initially flows from all the lower pipes 5 until it overlaps them with a bookmark, then begins to flow into the side 5, and after they overlap them with a bookmark, the top nozzles 6. Since the top nozzles 6 are of variable length and oriented according to the roof configuration, The blend mixture is fed to remote and inaccessible places (mainly domes). When this occurs, the filling of almost the entire chamber and the formation of a monolithic structure; tab - host rocks.
