Summary:The invention discloses a method for directly building tailing ponds without filling positions above a goaf. Through the research on the goaf (2) and the rock mechanic experiments on a jamb (3), roof rocks (4) are regulated and cut into crossed irregular post bodies in blocks for carrying out stability analysis, the elastic plastic finite element analysis is carried out on the goaf (2) under the loading of the tailing ponds (5), the tailing ponds (5) are built under the condition without processing the goaf (2), and the tailing ponds (5) mainly comprise initial dams (6), tail sand piling dams(7) and water discharge systems (8). According to the invention, the tailing ponds are directly built above unfilled goaf, thus the potential safety hazard of directly building the goaf above the oversized goaf can be eliminated, the normal production of a large-scale deep well mine can be ensured, and the goaf processing cost, the tail sand piling and storage long-distance conveying cost and theoperation cost can also be
