Abstract

The invention discloses a midline type tailing dam which comprises an initial-stage dam and a tailing stacking dam, wherein the tailing stacking dam comprises a first stacking area, a second stackingarea, a third stacking area, a fourth stacking area and a fifth stacking area; the first stacking area is formed through stacking fine-grain tailings graded by a hydrocyclone; each of the second stacking area, the third stacking area, the fourth stacking area and the fifth stacking area is formed through stacking coarse-grain tailings graded by the hydrocyclone; and the tailings permeability coefficient of the third stacking area and the fourth stacking area is greater than that of the fifth stacking area, and the tailings permeability coefficient of the fifth stacking area is greater than that of the second stacking area. According to the midline type tailing dam, the midline type tailing dam is divided into different areas, and the corresponding tailings permeability coefficient is controlled according to the characteristic of each area, so that different areas can better play the respective roles, the dam body seepage line is lowered, and the dam body stability is improved to further improve the essential safety of the midline type tailing dam.

Description

technical field [0001] The invention relates to the technical field of tailings dams, in particular to a centerline tailings dam. Background technique [0002] The centerline tailings dam is a tailings dam constructed by the centerline tailings damming method. The centerline tailings damming method uses coarse tailings to pile up the sub-dam and the downstream dam body. The current centerline tailings damming method at home and abroad The physical and mechanical properties of the tailings are strictly controlled. In the same project, the same physical and mechanical property control indicators are used for the tailings in different areas of the sub-dam and downstream dams, so that the tailings in the sub-dams and downstream dams in each area The permeability coefficients are the same. The permeability coefficient of tailings in each area of ​​the sub-dam and the downstream dam body is the same, and the purpose of having different functions in different areas of the centerli...
