Along with the application and popularization of the backfill coal mining technology, after gangue is fed into goaf, under the long-term leaching and soaking effects of mine water, heavy metal ions contained in the gangue are separated out from the gangue, and a certain impact is caused to the groundwater environment due to the movement and migration of a large quantity of heavy metal ions in the surrounding rock of goaf. No effective management method has been found yet in the prior art currently.
SUMMARY
The present invention aims at making up the blank of treatment for environmental pollution of heavy metal elements of the filling body in goaf of a coal mine, and discloses a system for controlling migration of heavy metal elements of the filling body in goaf based on the principle of electrophoresis, to gather and discharge heavy metal ions in goaf to protect the groundwater environment of the mining area.

The screen pipes are distributed on the floor of goaf, one screen pipe is distributed parallel to the coal face and at every interval of a set distance L starting from an open-off cut, goaf is full of the screen pipes uniformly, the screen pipes are equal to the coal face in length, water infiltrating holes are uniformly formed on the surfaces of the screen pipes, the screen pipes are wrapped with a plurality of layers of geotechnical fabrics, and the peripheries of the screen pipes are filled and covered with sand gravels.
The concentrated pipeline is arranged in a mining roadway, the screen pipes are connected to the concentrated pipeline, the water suction pump is arranged at one end, close to the impounding reservoir, of the concentrated pipeline, a water outlet of the water suction pump is connected to the impounding reservoir, a heavy metal ion concentration sensor is arranged respectively on the current-conducting plate connected to a negative electrode of the direct-current power supply in goaf and on the water outlet of the water suction pump, and the sensor is used for controlling the water suction pump to start and stop.
A water level sensor and the draining pump are arranged in the impounding reservoir.
One row of the current-conducting plates connected to one another in series are distributed parallel to the coal face in goaf and at every interval of L/2 starting from the open-off cut, goaf is full of the current-conducting plates uniformly, the current-conducting plate rows are equal to the coal face in length, and the current-conducting plates are upright; and the current-conducting plate rows located above the screen pipes are connected to the negative electrode of the direct-current power supply, and the remaining current-conducting plate rows are connected to a positive electrode of the direct-current power supply.
Preferably, the current-conducting plate is 1 m in height, 2 m in length, and 2 cm in width.

According to the present invention, the technical principle and work engineering of the system for controlling migration of heavy metal elements of the filling body in goaf based on the principle of electrophoresis are used. Heavy metal elements separated out from the filling body in goaf of the coal mine exist in the ponding of goaf in the form of cations. Under the action of an electric field force between two rows of current-conducting plates connected to the positive and negative electrodes of the direct-current power supply, heavy metal cations in water move towards the direction of the current-conducting plate connected to the negative electrode of the direct-current power supply. The heavy metal ion concentration sensor is arranged on the current-conducting plate connected to the negative electrode of the direct-current power supply, and the screen pipes are arranged below the current-conducting plates. When the concentration of heavy metal ions at the periphery of the current-conducting plate connected to the negative electrode of the direct-current power supply rises to a preset value, the sensor on the current-conducting plate controls the water suction pump to start to work, and when the concentration of the heavy metal ions at the water outlet of the water suction pump declines to a preset value, the sensor at the water outlet controls the water suction pump to stop working. A water level sensor is arranged in the impounding reservoir. When the water level in the impounding reservoir rises to a preset value, the water level sensor arranged in the impounding reservoir controls the draining pump to start to work, and when the water level in the impounding reservoir declines to a preset value, the water level sensor controls the draining pump to stop working.

Each current-conducting plate is 1 m in height, 2 m in length, and 2 cm in width. As shown in FIG. 3, the current-conducting plates keep upright and implement circuit connection by virtue of a plurality of slots 8 fixed on the floor. Two adjacent slots of a same row have an interval of 2 m, and in each row of slots, except that the first slot and the last slot can only fix one current-conducting plate, others all fix two continuous current-conducting plates. The current-conducting plate row on the screen pipes 3 is connected to a negative electrode of the direct-current power supply 1, and the other current-conducting plates are connected to a positive electrode of the direct-current power supply 1.
All the screen pipes 3 are led to the concentrated pipeline 4 in a mining roadway, the concentrated pipeline 4 is led to the pre-constructed impounding reservoir 6, the water suction pump 5 is arranged at one end, close to the impounding reservoir, of the concentrated pipeline, a heavy metal ion concentration sensor is arranged respectively on the current-conducting plate connected to the negative electrode of the direct-current power supply in goaf and on a water outlet of the water suction pump, and the sensor is used for controlling the water suction pump 5 to start and stop.
Anti-seepage treatment is performed at the periphery and the bottom of the impounding reservoir 6, a water level sensor is arranged in the impounding reservoir, and the draining pump 7 is controlled to start and stop by the sensor.
Under the action of an electric field force between two rows of current-conducting plates connected to the positive and negative electrodes of the direct-current power supply 1, heavy metal cations in water move towards the direction of the current-conducting plate connected to the negative electrode of the direct-current power supply. The heavy metal ion concentration sensor is arranged on the current-conducting plate connected to the negative electrode of the direct-current power supply, and the screen pipes 3 are arranged below the current-conducting plates.

A water level sensor is arranged in the impounding reservoir 6. When the water level in the impounding reservoir rises to a preset value, the water level sensor controls the draining pump 7 to start to work, and when the water level in the impounding reservoir declines to a preset value, the water level sensor controls the draining pump 7 to stop working.
