Reasonable layout of a dewatering project in a coal mine is based on aquifer parameters inversion. Based on pumping tests without an observation well conducted at a certain mine, four methods such as linear graphic method, water level recovery, analytical method and optimal match were discussed and used to calculate the transmissibility of the aquifer in this paper. With an practical example, the transmissibility is verified according to the drawdown data of the dewatering well. The results show that the parameter values with the linear graphic and water level recovery methods are reliable.
