Abstract:Underground water pollution in coal mine area has the characteristics of concealment, high pollution and great harm. It is difficult to control groundwater pollution due to its deep pollution and complex geological structures. Because of different ways of generation and development of pollutant, the control and remediation of bedrock groundwater pollution have become the key issues. By using curtain grouting technology, optimization of grouting technology and well layout, the pollution can be effectively controlled, and the implementation effect and safety of water stop curtain can be ensured. Through building low permeability barriers around pollution sources, the migration routes of pollutants can be changed or blocked. In this paper, combining with the practice of groundwater pollution prevention, technology background, technology comparison and selection and technology research and development strategies have been analyzed. It will provide optimal solutions for dealing in contaminated sites.
