A dam-filling process of full tailings slurry flushing and filling mold bags with solidified body

Abstract

The invention discloses a dam-filling process of full tailings slurry filling mold bags and solidified bodies, and relates to the technical field of mold bag dam stacking, including dam structure selection, slurry making, three-dimensional three-dimensional drainage system construction, mold bag selection, and mold bag body Layout, mold bag body fixing, mold bag body filling, artificial drainage and other processes, this process, as a new technology to realize tailings slurry dams in tailings ponds, is an iteration and innovation of the previous mold bag dam building methods, not only the dam building process The method is simple and fast, and the formed dam body has a low infiltration line, high dam body stability, and high safety. In addition, the solidified dam body formed by the present invention can store and process -200 to -400 mesh tailings particles, and the dam body has a three-dimensional drainage system formed by dislocation and staggered arrangement of the solidified body of the mold bag, which is beneficial to Realize rapid drainage of mold bag solidified body, strong practicability.

Description

technical field [0001] The invention relates to the technical field of mold bag dam stacking, in particular to a dam stacking process of filling mold bag solidified body with full tailings slurry. Background technique [0002] At present, the storage of fine-grained silt-like fly ash, fine-grained silt-like tailings, and fine-grained silt is a major problem in the storage of industrial industries in my country. During the storage process, it is often necessary to build a dam for storage, and the cost of building a dam is huge. And it takes up a lot of land resources. With the improvement of technology, more and more fine mud enters the ash storage, tailings storage and rivers and lakes, and more mines enter the tailings of the tailings storage to reach -200 ~ -400 mesh. When the tailings storage runs to a certain period , fine mud cannot be deposited, and the environmental protection pressure of tailings pond drainage is huge. However, the traditional mold bag dam technolog...

AI Technical Summary

Problems solved by technology

However, the traditional mold bag dam technology solves the problem of fine-grained tailings storage with poor work efficiency and slow speed, and cannot quickly realize the accumulation of fine-grained tailings, which often cannot meet the production needs of enterprises.

[0003] In addition, in the past mold bag dam construction technology, there are significant shortcomings in the sewing of the mold bag, the fixing of the mold bag, and the filling thickness of the mold bag

For example, the stitching of the existing mold bag has the phenomenon that the long side of the mold bag is stitched longitudinally, destroying the warp and weft of the mold bag, the strength index is not high, and the bag is easy to explode after the filling stress increases; the existing mold bag fixing method is not reliable, Easy to move, easy to slip bags; the existing mold bag filling thickness is not high, and requires multiple processes, multiple flushing results in a waste of labor and a large amount of materials

In addition, because the dry beach of the tailings reservoir is not easy to form, the dam body has a high seepage line, and the dam body has poor stability and safety
