Abstract

The invention relates to the development of deposits located in areas with permafrost. The purpose of the invention is to increase the carrying capacity of the array and to intensify the process of freezing ice.

Description

The invention relates to mining, in particular, to the development of deposits located in areas with permafrost, and can be used to obtain laying of the developed space and freeze artificial ice breeds.

The purpose of the invention is to increase the carrying capacity of the array and intensify the process of freezing ice.

FIG. Figure 1 shows the structure of the device, which allows to obtain a dust / air mixture; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. one.

Dust fractions of the rock, for example, quartz dust, which pass through the through channels in the electret 2, are supplied through the pneumatic tubing 1, electrified, acquire a positive charge. Then the charged dust-air mixture enters the mixing chamber 3, where the dust is mixed with water, supplied through conduit 4. Next, the air / water mixture is conveyed through transport conduit 5 to the bookmark site where it is layer-by-layer cooled. The dust-air mixture is obtained as a result of ejection mixing of air and dust fractions of rock coming from the bunker 6.

The electrolyte is a disk 7 in which cylindrical channels 8 are made at an angle of 70 ° to its plane and protective shell 9. Dust fractions of the rock, passing through channels in the electret, acquire a positive charge. The channels are angled to create vortex flows, impingement

particles in flight. This increases the number of dust particles that are positively charged. The charged dust particles mixed with water remain in suspension for a long time, evenly distributed throughout the volume of water.

Freezing of water saturated with dust fractions of the rock, whose structure is similar to the structure of ice, for example

quartz dust occurs much faster than ordinary water.
