Abstract

The invention provides a tailings reverse filter material, a preparation method and its application, a reverse filter material drainage structure and its application, and specifically relates to the technical field of tailings treatment. The tailings anti-filtration material includes stacked gravel layers, gravel tailing sand joint transition layer and tailing sand layer; the gravel tailing sand joint transition layer includes gravel and tailing sand, and the tailing sand is filled between adjacent gravels gap. The seepage drainage structure of the reverse filter material includes the seepage drainage pipe and the gravel layer arranged in sequence outside the drainage pipe wall, the gravel tailing sand combined transition layer and tailing sand layer, and a filter screen, which is sleeved on the Outside the seepage drainage pipe, it is arranged between the gravel tailings joint transition layer and the tailings layer. Drainage holes and partitions are arranged around the seepage pipe. The tailings reverse filter material and reverse filter material drainage structure provided by this application can accelerate the discharge of water in the tailings, prevent silting, improve the degree of consolidation of the tailings, reduce the infiltration line during the accumulation of the tailings, and ensure that the tailings The bearing capacity and shear strength of the dam improve the safety of the tailings dam.

Description

Tailings reverse filter material, preparation method and application, and reverse filter material drainage structure and application technical field The present invention relates to tailings treatment technical field, especially relate to tailings reverse filter material, preparation method and application and reverse filter Material drainage structure and application. Background technique Due to the increasing depth of mineral mining and beneficiation technology, the tailings particles in the existing tailings dam are becoming more and more Thin, it is difficult to remove seepage water, resulting in a high infiltration line of the dam body, and the mechanical properties of the tailings dam are getting worse and worse, affecting the safety and stability of the dam body sex. [0003] In view of this, the present invention is proposed. SUMMARY OF THE INVENTION One of the objects of the present invention is to provide a kind of tailings anti-filter material, to allevi...
