The water-soluble mining is often accompanied by ground subsidence, which could result in the severity of ground subsidence disasters. The roof of the salt-bearing strata in the Longgui salt rock mining area is close to the third aquifer, which is mostly composed of muddy conglomerate and other porous rocks with large porosity and permeability. The water-soluble mining for many years has caused serious ground subsidence in the mining area, and there is a tendency to accelerate subsidence. Taking Longgui salt rock mine as a case, the mining subsidence mechanism was analyzed and discussed through the water dissolution simulation test. This study is of great significance to the prevention and control of ground subsidence disasters in Longgui salt rock mine, and also has certain reference value for other similar mining areas.
