The conductive plates (2) are arranged at regular intervals in rows, which are equal in length to a coal mining face, in parallel with the coal mining face within a goaf, each two adjacent conductive plates (2) are connected to different poles of the direct current power supply (1), and the filter tubes (3) are arranged beneath the conductive plates (2) connected to the power supply negative pole. Heavy metal ions gather around the conductive plates (2) connected to the power supply negative pole under the effect of an electrical field, and the water extraction pump (5) is started so that contaminated water passes through the filter tubes (3) to be collected in the water reservoir (6) via the central pipeline and discharged to the ground via the water drainage pump (7) for treatment. The system effectively controls the migration of heavy metal ions in goaf surrounding rock, and reduces the contamination of groundwater environments by goaf coal gangue filling body heavy metal ions.
