According to the characteristics of the ancient rock salt deposits and the nature of the ore, the mining methods include dry mining and water mining. Under normal circumstances, shallow low-grade mining tunnels and diverticum water-soluble mining methods, while deep high-grade ore mining multi-purpose drilling water-soluble mining methods. From the perspective of development trends, the application of water-soluble mining methods will be more and more. The mining process of rock salt deposits is classified as shown below.

1) Dry mining method, suitable for rock salt deposits with shallow burial or exposed surface, wide distribution area and dry operation. The main mining methods for underground mining are the room-column method and the long-wall method, that is, through mining, mining, and mining, the mined ore is transported from the underground to the ground, and processed into finished salt.
2) Drilling water-soluble mining method (also known as borehole water-soluble mining method): It is one of the methods of water mining. This method is similar to oil production. People only need to work on the ground, inject fresh water into the ore layer through drilling, dissolve the ore into liquid (ie artificial brine), then pump it to the ground with a pump or other equipment, and then process it to make the finished salt. .
3) Dip chamber water-soluble method: it is one of the water-soluble mining methods. The process is similar to the underground mining (dry mining) of the room and pillar mining method, which is mainly distinguished from the mining stage. At this stage, the method is introduced into the initial diverticulum by fresh water (equivalent to the reclaimed mining room of the room and pillar method), and dissolved. The ore body (mainly dissolved in the upward direction, supplemented by side dissolution), and then the high-concentration brine that can be directly used from the diverticulum is pumped to the ground for salt production.
This method is especially suitable for ancient rock salt deposits with low NaCl content, more water-insoluble matter, and difficulty in mining with room-column mining and drilling water-soluble methods.
