Embodiment 1
[0036] Such as figure 2 , image 3 , Figure 4 and Figure 5 As shown, a centerline tailings dam construction method using mold bags can specifically include the following procedures:
[0037](1) Construction process of mold bag grouting system: according to the height and axis position of the current dam body, set up a high-level ore slurry pool 8 at a height of at least 15m higher than the dam crest, and lay an ore-drawing pipeline 9; the top of the ore-drawing pipeline 9 It communicates with the bottom of the high-level slurry pool 8, and the bottom of the ore-drawing pipeline 9 extends downstream of the current dam body.
[0038] Specifically, when there is only the initial dam 1 in the tailings reservoir, the current dam body is the initial dam 1, and when the initial dam 1 already has a heap dam, the current dam body is the current heap dam. The height of the high-level ore slurry pool 8 can be increased along with the height of the dam crest of the current dam body...
