The method of filling the shafts of the mines, extractive water-soluble ore (options)

 

The invention relates to the mining industry and can be used for the elimination of shafts in existing plants. The technical result - securing support complex on all the protected period. In the method of filling the shafts of the mines, extractive water-soluble ore, including backfilling shafts inert materials, initially perform a full filling trunks specified ore or salts contained in the ore, and maintain it throughout the protected period, at the end of which the filling force is dissolved, and the trunks fall asleep inert materials. In another embodiment, a method of backfilling shafts of mines, extractive water-soluble ore, including backfilling shafts inert materials, backfilling shafts inert materials is carried out before the area groundwater, saturated salts, above which the remaining part of the trunk fall asleep ore or salts contained in the ore, and maintain it throughout the protected period, the filling force is dissolved at the end of the protected period, and then the trunks completely asleep inert materials. 2 C. p.

The invention relates to the mining industry and can be ispolzovaniya the exit to the surface, should be filled.

The elimination of shafts carried out in a planned manner (in the case of mining stocks), and in emergency situations, for example in the case of flooding of the mine. As in the first and second cases, you can enter the mine through the barrels of fresh water. The incoming water will dissolve the salt rocks, resulting is formed on the surface of the basin, which will have a negative impact on the buildings located on the earth's surface.

The technical result of the invention is to provide a safety support (surface) of the complex on a specific (protected) period.

The known method the planned liquidation of the shafts, which consists in filling the lower zone of the shaft inert material (rubble of hardwood), then under construction waterproofing design (castle), then poured the gravel in the upper zone (Heinz Bush. Research project on sealing of underground waste repositories, implemented in the trunk "Salzdetfurth II"// glückauf, 1999, March(I), S. 16, Fig. 2).

The closest in technical essence and the achieved result to the proposed technical solution is the way to eliminate the shaft of work on conservation and redevelopment of the company for the extraction of potash and rock salt// glückauf, the special issue, 1998, March, S. 40-41, Fig. 1).

However, these methods cannot be used in the event of liquidation shafts flooded mine due to the inability of the device in the barrel, filled with brine preserved reinforcement, reliable waterproofing design (castle).

In the first version of this technical result is achieved by the fact that in the first embodiment of the method of filling the shafts of the mines, extractive water-soluble ore, including backfilling shafts inert materials, initially perform a full filling trunks specified ore or salts contained in the ore, and maintain it throughout the protected period, at the end of which the filling force is dissolved, and the trunks fall asleep inert materials.

The essence of the method is illustrated in the drawings, in which: Fig. 1 - scheme of the first stage backfill drainage, Fig. 2 is a diagram of the final backfill (liquidation) of the allotment.

The method is as follows.

Originally produced backfilling shafts 1 ore or lileokalani 2 to the concrete lining of the mouth 3 of the barrel. This level of backfill support continuously, i.e. as shrinkage (natural dissolution) colodado during the whole time of the protected period, the belt use of industrial buildings and structures.

At the end of the protected period, the trunks fall asleep inert materials 4 (crushed stone, gravel). The filling is produced (Fig. 2) with forced dissolution of colodado (salt), which is performed by, for example, the supply of fresh or brackish wastewater.

In this case, the time before the formation of the mould displacement, i.e., dangerous for protected structures deformations, is increased by the time the enterprise plus the time for dissolution of the rock mass and the formation of mould, that is, beyond the life of the plant and additional protection measures will be required.

Known method of eliminating shafts, consisting in filling shaft inert material (rubble of hardwood), then waterproofing design (castle), then put the gravel in the upper zone of the salt rock mass (Heinz Bush. Research project on sealing of underground waste repositories, implemented in the trunk "Salzdetfurth II" //glückauf, l999, March (I), S. 17, Fig. 2).

Closest to the proposed technical solution is the way of liquidation of the shaft, assuming the initial filling of the barrel with gravel from solid GIII (Heinz Bush. Research project on sealing of underground waste repositories, implemented in the trunk "Salzdetfurth II"// glückauf, 1999, March (I), S. 16, Fig. 1) However, these methods cannot be used due to the complex design, the creation of which requires time and conditions, i.e., it can only be done in a planned manner.

The technical result of the invention consists in securing support complex on all the protected period.

In the second embodiment, the specified technical result is achieved in that in the method of filling the shafts of the mines, extractive water-soluble ore, including backfilling shafts inert materials, backfilling shafts inert materials is carried out before the area groundwater, saturated salts, above which the remaining part of the trunks fall asleep specified ore or salts contained in the ore, and maintain it throughout the protected period, the filling force is dissolved at the end of the protected period, and then the trunks completely asleep inert materials.

The essence of the method is illustrated by a drawing, in which Fig. 3 is a diagram backfill shaft (the second option).

The method is as follows.

Originally produced backfilling the b backfill was in the zone of groundwater 5, saturated salts. On the top of the column of inert fill 4 fill Soledad 2. As dissolution of colodado (salt) penetrating into the barrel waters produce their dosaku. Thus, the barrel retains within the required time (the protected period) at the end of which the filling of colodado 2 forcibly dissolved and completely fill the barrel with inert materials 4.

The advantages of this option are that filling the lower part of the trunk inert materials reduces and simplifies the subsequent backfilling of the barrel. In addition, during the formation of the mould movement also extend beyond the term of the protected period, i.e., will not require additional conservation measures.
