Abstract

The invention discloses a real-time water-level monitoring system for a dumping site of an open-pit coal mine. The dumping site of the open-pit coal mine comprises an aboveground part and an underground part, where the aboveground part is a stacking site (1) located above an original ground surface. The real-time water-level monitoring system for a dumping site of an open-pit coal mine comprises a first measuring well (2) and a second measuring well (3), where the first measuring well (2) is arranged vertically in the center of the stacking site (1), and the second measuring well (3) includes a vertical section (301), a horizontal section (302), and a free section (303) connected in sequence; and a first water-impermeable layer (4), a second water-impermeable layer (5), and a third water-impermeable layer (6) are provided internally in the stacking site (1).
