[0026] like Figure 1 As shown, a water discharge system for collecting parameters of aquifers in mines includes a water discharge pipe 3, a parameter acquisition unit 13, a baffle 6, and a sealing bag 5. Exploration holes are drilled using a drilling machine. Before or after drilling, the top layer is surveyed to determine the depth of the aquifer 1. The hole is drilled to a certain depth within the aquifer 1, but this depth is not limited here. The water discharge pipe 3 is a stainless steel metal pipe. One end of the water discharge pipe 3 extends into the exploration hole, and this end is preset according to the exploration data. The other end is bent and connected to the first control valve 11, thereby reducing intrusion into the mine space and allowing the mine to be protected along the mine floor 2 or other waterproof structures. The parameter acquisition unit 13 extends from the side wall of the location and is located in the middle of the water discharge pipe 3. It is used to collect the water pressure and flow rate inside the water discharge pipe 3. The parameter acquisition unit 13 is connected to the storage unit 15 through the converter 14.
