摘要：

Groundwater pollution is the main environmental issue of underground coal gasification. Groundwater pollution is caused mainly by the dispersion and penetration of contaminants generated by underground gasification process towards surrounding strata, and the leaching of the underground residue by natural groundwater flow after gasification. Migration of the contaminants tends to decrease both with time and distance from the burn cavities due to the interaction between the contaminants and rock strata or coal. Preliminary measures for groundwater pollution control and restoration regarding UCG process were put forward.
