Example Embodiment
[0006] Example 1: On a pressure-bearing brine reservoir of a salt lake, a trenchless engineering drill was used to select a suitable location to incline and install a solvent flower tube into the pressure-bearing brine reservoir, and then pass this solvent flower tube Input the fresh water solvent into the pressure-bearing brine reservoir, and then lay a suction pipe into the pressure-bearing brine reservoir obliquely, and the brine and dissolved solid salt of the pressure-bearing brine reservoir are transported through the suction pipe To the ground to be used.
Example Embodiment
[0007] Example 2: Its specific implementation is the same as Example 1, except that the solvent does not use water, and the solvent uses unsaturated brine.

The invention belongs to the technical field of salt lake resources exploitation, in particular to a collecting method of salt lake bearing brine-storing layer brine and solid salts. The steps of the method comprise employing a trenchless construction drill to construct and arrange solvent floral tubes obliquely downwards for the bearing brine-storing layer, feeding solvent in the bearing brine-storing layer from the upper end of the solvent floral tubes, then constructing and arranging pumping floral tubes obliquely downwards for the bearing brine-storing layer and transporting the brine of the bearing brine-storing layer and the dissolved solid salts to the ground surface. According to preliminary estimate, the method can save more than 50% capital investment, can save more than 33% operating and maintenance cost of exploiting and transporting the brine, adds about 1-5 times of the exploitation quantity of the brine and the solid salts resources, and enables 'dead mine' to change into live mine, thereby having relatively large economic benefit and social benefit.
Description
1. Technical field: [0001] The invention belongs to the technical field of salt lake resource exploitation, and in particular relates to a method for mining brine and solid salts in a pressure brine storage layer of a salt lake. 2. Background technology: [0002] At present, in the exploitation of modern salt lake resources, only rich ore brine and solid salts located in the shallow surface can be mined. The method of mining rich ore brine is direct suction, while solid salts are directly excavated or dissolved in fresh water. The method of pumping brine is used for mining. However, these resources located on the shallow surface are limited, usually only accounting for 1 / 10 to 3 / 10 of the total resources of the salt lake. The mining and utilization of human resources is a technical problem that people urgently need to solve. However, the geological age of the formation of the pressurized brine storage layer is a little longer, and it has experienced geological structure ch...
