Abstract

The invention discloses a method for increasing mine tailing storage reserve based on the designed storage capacity, which belongs to the field of increasing the storage capacity of a mine tailing storehouse. The method comprises the following steps: firstly, laying a layer of working face on original mine tailing slurry in a mine tailing storehouse, arranging a vertical drainage channel in the working face, and setting a horizontal drainage channel on the working face so as to discharge water in the original mine tailing slurry discharges through the vertical drainage channel and the horizontal drainage channel due to the dead weight of solidified tailing soil or tedded tailing soil subsequently stacked on the mine tailing slurry to turn the slurry into a self-supporting soil body with sufficient strength by drainage solidification; and secondly solidifying or tedding tailing slurry subsequently injected to turn the slurry into self-supporting tailing soil with sufficient strength and then stacking the tailing soil on the working face in layers till the final stacking height is achieved.

Description

technical field

[0001] The invention belongs to the technical field of mining, relates to the field of capacity expansion of mine tailings storage, and specifically refers to a method for increasing the storage capacity of the tailings storage which has reached the designed storage capacity. Background technique

[0002] The large amount of ore debris and powder remaining after extracting the active ingredients from the ore is called tailings. The disposal of tailings is usually to mix these tailings with a large amount of water to make a very thin tailings slurry, and then use a pump to pass through the pipeline. Transport to designated place for storage. In order to store these fluid slurries, it is usually necessary to build a dam (called a tailings dam) to prevent the slurry from leaking out and form a tailings pond. Because the fluid mud will generate a large horizontal force on the dam body, and this force increases exponentially with the increase of the dam height, s...
