The salt field in Yexian County, Henan Province covers an area of more than 400 square kilometers. The predicted resource reserves of the entire salt-bearing basin are 330 billion tons, accounting for 75% of the salt mine resources in Henan Province. At present, the proven reserves rank first in the country and can supply all Chinese people. Eat for 50 years.

Yexian has a high grade of rock salt. The average grade of sodium chloride in my country's salt mines is generally 35% to 95%, and the grade of sodium chloride in Yexian salt mines is between 85 and 95%, which is of high quality.

The burial depth of rock salt in Yexian County is moderate, which is conducive to mining and utilization. Most of the rock salt deposits in my country are buried between tens of meters and 4,000 meters underground. The surface of the shallow salt layer is easy to subside after mining, but the mining cost is high if buried too deep. The rock-salt layers in Yexian County are all between 1100 meters and 1800 meters underground. The mining cost is low. At the same time, the mining is strictly carried out according to the design. The salt layer is not complicated, and the thickness of the single layer is large. Yexian salt layer is not complicated, and the thickness of the single layer is large. For example, the 63 layers of salt layers in the ore section of the Hetaoyuan Formation have a cumulative thickness of about 290 meters, a single layer thickness of 27 meters, and some are even greater than 27 meters.
