TY - JOUR TI - Ground subsidence mechanism analysis of Longgui salt rock mining area: Case study AU - Zhang Nan AU - Yang Jie AU - Shi Xi-Lin AU - Li Yin-Ping AU - Chen Jian AU - Liu Wei JN - Thermal Science PY - 2020 VL - 24 IS - 6 SP - 3869 EP - 3875 PT - Article AB - 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.
