Abstract

The invention relates to the construction of underground structures and increases the watertightness of the fence by eliminating the mixing of fresh water with highly mineralized brines. Around the ore body in the watertight formations, a drill of 1 main and a number of 2 additional wells. In the first period, highly mineralized brines of the liquid are pumped through wells of row 2 and simultaneously non-saline fresh water is pumped through wells of row 1. In the second period, highly mineralized brine fluids are pumped through wells of row 1, and fresh water is pumped through wells of row 2. Rows 1 and 2 are alternated to replace the highly mineralized brine with non-saline water. Then freezing works are performed.

Description

The invention relates to the construction of underground structures and can be used to create waterproof jumpers in quarries in rocks containing highly mineralized brines.

The purpose of the invention is to waterproof the enclosure by eliminating the mixing of fresh water with highly mineralized brines.

The drawing shows the layout of the rows of pumping and injection wells.

The process is carried out as follows.

To create a monolith of a waterproof barrier around the ore body in waterproof rocks of a row 1 and 2 wells. In the first period, highly mineralized brine fluids are pumped out through wells of row 2 and, simultaneously, wells of fresh mineral water are pumped through wells of row 1.

In the second period, highly mineralized brines of the liquid are pumped out through wells of row 1, and through the well, the method of creating ice-soil protection in bypassing highly mineralized brines rocks, including drilling along the contour of the enclosed array of wells, freshwater is fed into the wells before replacing the strains that are in the well-protected well, to replace the well. cooling expense, as distinguished by the fact that, in order to increase the water tightness of the enclosure by eliminating the mixing of fresh water with highly mineralized ssolami around the partition array drilled additional row of wells and simultaneously pumping fresh water through Niemi one row

women of yes 2 pump fresh water.

Perform alternating p - wells and pumping out fluid.

Dows 1 and 2 before replacing high mineralization from another row of wells with mutual

brine on the non-mineralized alternating series.
