A device for accelerating drainage and consolidation of wet pile tailings step by step

Abstract

The invention belongs to the technical field of tailing pond disaster prevention and particularly discloses a stage-by-stage wet stacking tailing drainage acceleration and consolidation device. The device comprises a main support, a main floating body, a convolution box and a slurry cake removal device. The main support is formed in the mode that the top end and the bottom end which are formed by two opposite supporting frames are connected with an upper steel ring and a lower steel ring at the same time respectively. The main floating body is arranged between the upper steel ring and the lower steel ring. A square through hole is formed in the middle of the main floating body. The two opposite supporting frames penetrate through the middle of the main floating body and are attached to the two inner sides of the square through hole respectively. The convolution box is fixedly installed in a space formed by the two opposite supporting frames. The lower steel ring of the main support is fixedly connected with the slurry cake removal device. Through the method, efficient drainage and consolidation in the whole process of sedimentation and consolidation of wet stacking tailing slurry can be achieved, the problems about tailing drainage and consolidation in the pond are effectively solved, the tailing consolidation process is accelerated, safety of the tailing pond is effectively improved, and an effective means is provided for tailing pond disaster prevention.

Description

technical field [0001] The invention relates to the technical field of disaster prevention and control of tailings dams, in particular to a device for accelerating drainage and consolidation of step-by-step wet stack tailings. Background technique [0002] As a special industrial building, the tailings pond is an essential infrastructure for the production of mining enterprises, but it is also a high-risk source of man-made debris flow hazards. Due to the special tailings stacking process and storage environment, the perennial water accumulation in the tailings pond is serious, the degree of mud consolidation is extremely low, and the infiltration line of the dam body is too high, resulting in the collapse of the dam body and the leakage of mud from the mud discharge pond in the karst area. Dam breaks and other tailings pond disasters occur frequently. [0003] Whether it is the dam failure or collapse accident caused by seepage damage of the upstream tailings accumulation ...

AI Technical Summary

Problems solved by technology

On the one hand, most upstream tailings ponds adopt hydraulic transportation and wet storage of tailings. Tailings slurry has the characteristics of low permeability, high void ratio, and high moisture content, and the maximum moisture content can reach more than 300%; on the other hand Due to the lack of effective drainage channels, the tailings accumulation in the reservoir caused serious water accumulation in the reservoir, and a large amount of accumulated water in the reservoir could not be discharged in time, especially for large tailings reservoirs. It takes a long time to complete the consolidation, and the consolidation period is quite long
