Abstract

The invention relates to the mining industry and is intended to fill the inclined chambers with a hydrophore bookmark during the development of a hollow parade of high power. The goal is to reduce the cost of backfilling while increasing the completeness of the bookmark. For this, the mine workings are made and, at the same time, the accumulator is formed with soil inclined towards the chamber. A filling solution is initially fed to the accumulator before covering its soil, then the rock and the filling solution simultaneously before filling the accumulator with the formation of a slurry. After that, the last is passed into the chamber. This reduces the volume of backfilling workings and increases the completeness of filling due to the energy of the moving stream. 3 silt. SUMMARY The invention relates to mountainous occupancy and is intended to fill the inclined chambers with a hydrophore insert during the development of gently sloping ore bodies of high power. A method of developing ore deposits with hydraulic explosion of ore on the soil of the inclined chambers is known. In this method, the ore is delivered by explosive heap on the stream of water flowing from the storage tank along the inclined bottom of the chamber. The disadvantage of this method is that the delivery of ore by the stream of water is coupled with explosive works, requires a large amount of water. since for a short period of delivery, no mud flow is formed from the ore mass. The method of camera laying, which is the closest to its technical essence, is known, including the drilling of backfilling, drilling wells from them to feed adobe mortar, conducting excavations to feed the rock, feeding the rock to the bottom of the chamber to form cones and then simultaneously feeding the filling solution to the peripheral parts of the chamber and the rock to the central part of the chamber, creating a rock cushion breaking the bottom of the chamber before feeding the rock, feeding the rock to the backwater formed by the cones the roof of the chamber, the flow of rock into the central part of the chamber through the slit formed in the roof successively. The disadvantage of the known method is that the rock bed forms only nuses from the ground to the roof of the chamber due to the bedding of rocks from rising from: filling the horizon with the delivery of rock on the horizon or the formation of cones in an explosive way from rising above the chambers, resulting in a necessary-OVI00OJ

Description

the storage of the spent space of the chamber increases the cost of transporting the filling solution and rock. In addition, when using this method, a large amount of stowing workings is required (drilling ort in the roof of the chamber, a gap for transferring waste rock, drilling of filling wells, drilling the soil chamber to form a rock blanket, working out for feeding rock).

The purpose of the invention is to reduce the cost of backfilling work in the chamber and increase the completeness of the laying of the goaf.

The goal is achieved by the fact that when the filling workings are driven into the hopper (bunker), located in the roof covering array with the soil tilted towards the edge of the chamber, the hydraulic folding is applied until the soil is completely covered and then both the waste rock and the hydraulic folding are applied until the accumulator is filled, after which the resulting mixture released through the window.

Figure 1 shows the camera, top view; figure 2 - section aa in figure 1; on fig.Z section bb in figure 2.

Camera 1 is laid out of a storage unit (bunker) 2, decorated in the roof covering part of the array, inclined towards the edge of camera 1 by angle of 8-10 °. For this, through the hydraulic shut-off line 3, a hydraulic folding 4 is injected into the hopper 2 until the soil 2 of the hopper 2 is completely covered. Then, 9 are fed into the hopper 2. J

from the rising 5 waste rock, and along the hydraulic line 3, the bookmark forms a pile 6 on the soil of the accumulator 2. Then the rock pile 6 is impregnated with a hydraulic insert 4. After filling the accumulator 2 with a hydraulic folding 4 and rock 6, they open the valve 7 and dump the filling mixture on the overflow slope 8 into the chamber 1. Filling chamber 1 start from jumper 9 in

the lower part of the chamber 1 and reach the thrust height of the developed space due to the conservation of the energy of the moving stream.

The proposed method compared with

known allows to significantly reduce the cost of laying the camera and increase the completeness of the laying of the goaf.
