英文摘要The Meiguiying mine is a famous underground coal gasification (UCG) mine in China, but there has been a potential safety hazard since it began operating, that groundwater in the overlying aquifer might enter the mine and even extinguish the gasifier. A 3-D hydrogeological model was developed to explore the characteristics of the seepage field of the aquifer and determine an optimal water pumping and injection option for the UCG. The results indicate that more attention should be paid to control induced fractures of the roof due to the increasing water level of the aquifer, and that a pumping rate of 160 m(3)/day would decrease the water level to a reasonable elevation. Moreover, to maintain the groundwater table and mine safety, 120 m(3)/day was recommended as a reasonable and economical recharge (re-injection) rate in the study area.
