Ground subsidence mechanism analysis of Longgui salt rock mining area: Case study
View through CrossRef
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.
