Abstract

METHOD OF FILLING THE DEVELOPED CAMERA SPACE, including building a hardened layer of hardening material in the bottom of the chambers of each horizon and filling them with a filler / whose tab, characterized in that, in order to reduce the cost of filling the chambers when working from top to bottom, For each lower chamber, the reinforcement layer in the overlying chamber is destroyed and the subsequent filling of the developed space is performed through the upper chamber.

Description

: c The invention relates to the mining industry and can be used in the development of mineral deposits by systems with the laying of a top-up chamber space from top to bottom. There is a method of developing ore deposits, including the laying of the goaf, with the filling material being bypassed from the downstream chambers into the underlying ones. The disadvantage of this method is the need for additional costs for dozakladka chambers. The closest to the described method is the method of mining ores, including the extraction of mineral primary and secondary chambers, bookmarking

spaces, with the laying of secondary chambers carried out with a loose laying, which is placed on a hardened layer of hardening material in the bottom of the chambers.

The disadvantage of this method is the high costs associated with the need to transport backfill materials to each horizon.

The purpose of the invention is to reduce the cost of backfilling.

The goal is achieved by the fact that in a known method, including the erection of hardened cnoh from hardening material in the bottom of the chambers of each horizon and filling them with his son: spaces are produced through overlying chambers.

Fig. 1 and 2 shows a section through the chamber across the ore body at the stage of filling the main volume of the upper chamber with a friable bedding and erection of the hardened layer in the underlying chamber; in fig. 3 and 4 are the same in the stage of destruction of the reinforced layer of the adjacent chamber and options for filling the upper chamber from a constant loading point.

from a constant loading point through a concentration-bedding development, for example, a stowing hole 11, traveled from the surface to the chamber,

5 or the development of a ventilation-stowing horizon 6 of the uppermost chamber 1.

Thus, filling the developed space of chamber 4 is performed by moving the backfill material, including the collapsed hardening tab 10 and bulk tab 3, from the overlying chamber 1 under its own weight, and then continue to fill chamber 1 with a loose tab 3 from a constant loading point.

When filling the underlying chambers, the work cycle is repeated.

The use of the proposed method allows to reduce material and labor costs for backfilling by simplifying the technology, since the filling of the main volume of waste chambers is done by moving the filling material under its own weight from the overlying chambers to the underlying ones, and feeding the bulk filling material from a stationary place. loading allows to increase the 1st concentration, mechanization and safety of the backfilling operations, which also reduces the labor and material costs. 312 Filling the developed space of the upper chamber 1 includes the construction of a hardened layer 2, for example, from a hardening bookmark and a bookmark of the main volume of chamber 1 with bulk material, rial (tab 3), for example, empty rocks from mining works. Then, after working the chamber 4 and erecting insulating jumpers 5, the hardening mixture 7 is fed from the workings of the ventilation-stowing horizon 6 and the reinforced layer 8 of the chamber 4 is erected. After that, the strengthened layer 2 of the upper chamber 1 is destroyed, for example, by drilling and blasting 9. As a result of the destruction of the hardened layer 2, the main volume of the chamber 4 is filled with a collapsed hardening tab 10 and a loose tab 3 supplied to the chamber 1
