Full tailing slurry filling mold bag solidified body dam stacking process

Abstract

The invention discloses a full tailing slurry filling mold bag solidified body dam stacking process, and relates to the technical field of mold bag dam stacking. The full tailing slurry filling mold bag solidified body dam stacking process comprises the steps of dam type structure type selection, slurry making, three-dimensional drainage system construction, mold bag type selection, mold bag body arrangement, mold bag body fixation, mold bag body filling, manual drainage and the like. The full tailing slurry filling mold bag solidified body dam stacking process used as a novel technology for achieving tailing pond full tailing slurry dam stacking is an iteration and innovation of an existing mold bag damming mode, the damming process is simple and convenient, the mode is fast, the formed dam body is low in infiltration line, and the dam body is high in stability and safety. In addition, tailings particles of -200 meshes to -400 meshes can be stockpiled and treated through the formed filling mold bag solidification dam body, a three-dimensional drainage system is formed in the dam body through staggered and staggered-layer arrangement of the mold bag solidification bodies, rapid drainage of the mold bag solidification bodies can be achieved, and practicability is high.

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
