Anti-seepage structure and anti-seepage treatment method for surface mine pit bottom
The invention discloses an anti-seepage structure and an anti-seepage treatment method for a surface mine pit bottom, and belongs to the technical field of mining. According to the anti-seepage structure for the surface mine pit bottom, the surface pit bottom is upwards sequentially paved with a lower cushion layer, a geomembrane, an upper cushion layer and a protective layer. The anti-seepage treatment method comprises the following steps: treating the surface pit bottom; treating the lower cushion layer; treating the geomembrane; treating the upper cushion layer; and treating the protective layer. According to the anti-seepage structure and the anti-seepage treatment method disclosed by the invention, the leakage problem of the surface mine pit bottom is solved with low cost, the anti-seepage effect is good, and the problems that under-mine water inflow is increased, under-mine water draining cost is increased, and even a mine flooding accident is possibly generated under a severe condition due to the fact surface water enters underground rocks along shallow broken gaps and floods into the pit along original small fractures when a lower ore body of the surface pit bottom is exploited after the surface mining is ended is effectively avoided.
