Embodiment Construction

[0020] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] The tailings reservoir dam break disaster displacement quantitative early warning method of the present invention, such as figure 1 shown, including the following steps:

[0022] S1. Set the safety factor of the early warning index of the tailings pond dam break disaster.

[0023] The safety factor of the early warning index of the present invention includes the safety factor of the first-level early warning index, the safety factor of the second-level early warning index, and the safety factor of the third-level early warning index. Among them, the safety factor of the first-level early warning indicators is set to 1, the safety factor of the third-level early warning indicators is set to 2, and the safety factor of the second-level early warning indicators is determined by the "Tailing Pond Safety Technical Regulations" (AQ20...

Abstract

The invention relates to a dam-break disaster displacement quantitative prewarning method of a tailings reservoir, which comprises the following steps: S1, dam-break disaster prewarning index safety factors of the tailings reservoir are designed; S2, under the prewarning index safety factors, the perwarning displacement of monitoring points of the tailings reservoir is calculated by using a finite element method; S3, the actual displacement of the monitoring points of the tailings reservoir is measured; S4, if the actual displacement is greater than or equal to the perwarning displacement, the perwarning is carried out. The dam-break disaster displacement three-stage quantitative prewarning method of the tailings reservoir has the advantages of quantification, practicability, high precision, wide engineering application prospect, and the like.

Description

technical field [0001] The invention relates to an early warning technology for dam break disasters of metal or nonmetallic mine tailings ponds, in particular to a quantitative early warning method for tailings pond dam break disaster displacements. Background technique [0002] Tailings pool refers to the tailings site formed by damming and intercepting valley mouths or enclosures, which is used to stockpile metal or non-metal mine ores and discharge them after sorting. As a major source of danger, once the tailings pond breaks, it will cause huge losses to the lives and property of people downstream and cause serious pollution to the surrounding environment. [0003] Displacement is the most direct indicator to reflect the occurrence of tailings pond dam break disaster. Monitoring the displacement index in the tailings pond project and implementing effective disaster warning are important measures to reduce the dam failure disaster of the tailings pond. At the same time,...
