Embodiment Construction

[0021] A method for building a tubular microporous tailings dam, comprising the following steps:

[0022] (1) Make the ore drawing pipe 3: the ore drawing pipe 3 adopts a medium and small diameter pipe, and the ore drawing holes 6 that are evenly arranged are drilled intermittently in the opposite direction under the ore drawing pipe 3;

[0023] (2) Install the ore-drawing pipe support 4: the ore-drawing pipe support 4 is arranged on the dry beach 5 in the storehouse, and the ore-drawing pipe support 4 is installed and fixed on the dry beach 5 in the storehouse with a set distance from the top of the sub-dam 2;

[0024] (3) Install the ore-drawing pipe 3: install and fix the prepared ore-drawing pipe 3 on the ore-drawing pipe support 4;

[0025] (4) Adjust the ore-drawing hole 6: open and block the ore-drawing hole 6 as required during ore drawing;

[0026] (5) Dam building: while the ore is drawn, the tailings are deposited into a sub-dam 2 with higher strength connected to ...

Abstract

The invention relates to a tubular microporous tailing damming method which comprises the following steps of: manufacturing an ore drawing tube: by using a middle and small diameter tube as the ore drawing tube, discontinuously drilling to evenly distribute ore drawing holes on the lower side of the ore drawing tube in the opposite directions; installing an ore drawing tube support: arranging the ore drawing tube on a dry inner-store beach, wherein the ore drawing tube support is installed by a preset distance and fixed on the dry inner-store beach; installing the ore drawing tube support: installing and fixing the manufactured ore drawing tube on the ore drawing tube support; adjusting the ore drawing holes: opening and clogging the ore drawing holes as required during ore drawing; and damming: depositing tailings to form high-strength sub dams connected with the initial dam during ore drawing. The invention has the characteristics of large dry beach slope ratio, large particle size of tailing deposited in front of the dam, high strength, good water drainage effect, low dam body seepage line, long effective dry beach, huge safe freeboard and good safety, and the method is applicable to ore drawing damming of middle and small tailing stores.

Description

technical field [0001] The invention relates to a processing method for tailings in a concentrator, in particular to a tubular microporous tailings dam building method for some small and medium-sized tailings dams with short storage length and relatively large terrain slope behind the storage. Background technique [0002] At present, there are many small and medium-sized tailing ponds in my country, and most of them use the upstream method to build dams. However, due to the poor terrain conditions of the tailings pond site, the length of the dry beach and the safety superelevation are difficult to meet the requirements, and the safety is poor. Although some of them have recently been changed to the dry discharge method, due to improper management, there are many potential safety hazards and it is not good for environmental protection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for building a tubul...
