Influence of underground coal gasification on groundwater resource
Abstract：Underground coal gasification (UCG)has re-emerged as an energy technology for coal conversion and utilization because of its advantages such as attractive economics, ability to access inaccessible coals and envi- ronmental friendly. The development status and economic and environmental benefits of UCG are introduced, and the organic and inorganic pollution of groundwater caused by UCG and remediation of polluted groundwater are also analyzed. Based on the analysis above it has been posed that problems, whether the pollutants will be gathered in groundwater or eliminated fully by the system composed of groundwater and surrounding rock when the coal seams are gasified in a large area.
