Influence of drainage of aquifer on settling of ground surface in mining area with high ground water level

Based on the basic principles of hydrogeology and soil mechanics, studied the genesis mechanism and control factors of settling of ground surface caused by the drainage of the aquifer in the construction of coal mines, and put forward a corresponding calculating model demonstrated by practical example. The study provides mining areas, which are covered with a very thick Quaternary soil layer and abundant ground water, with a theoretical basis aimed at forecasting the settling of ground surface.
