Abstract: Abstract：In order to ensure the safe and smooth mining of the 29 mining areas,the feasibility of the Taiyuan Formation limestone water drainage in panel 29 is studied;Through the water pumping and pressure releasing test on the bottom plate of the panel 29, the hydrogeological parameters such as the permeability coefficient of the main water-bearing section of the bottom plate are obtained; the well group disturbance theory and the unsteady flow theory are further used to predict the feasibility of floor drainage. The results show that the reasonable drilling arrangement and water release help lower the water table of the limestone aquifer, and the effect is remarkable. and it has practical feasibility. At the same time, it is of great significance to innovate the water control technology and reduce the cost of water control engineering.
