In order to accurately measure the depth and inrush of groundwater levels of different aquifers， the groundwater exploration project of Dongjiang Coal Base in Xinjiang uses an in-pipe stopper to stop the water in a hydrogeological exploration hole. Through the layered pumping test， the hydrogeological parameters of different aquifers were obtained. The pumping test of three landing processes of different aquifers in a hydrogeological exploration hole solves the problem that the hydrogeological parameters of different aquifers need to be obtained by implementing two exploration holes， saving the cost of well pipes， gravel and other materials， shortening the time of lowering pipes and filling gravel， and accelerating the progress of the construction.
