Problems solved by technology

However, the current anti-sliding stability analysis of the tailings dam slope only considers the mechanical stability of the tailings dam, and only takes the mechanical stability index of the dam body as the safety evaluation index of the tailings dam, which cannot meet the ecological environment protection and reliability of the tailings dam. The need for sustainable development
[0004] The traditional safety monitoring of tailings ponds is mostly carried out manually on-s

Embodiment 1

[0041] refer to figure 1 , the present invention proposes a method for analyzing the anti-sliding stability of the tailings reservoir dam slope based on the Swedish slice method, comprising the following steps:

[0042] Step 1: Determine the scope of the tailings dam according to the on-site geological survey, and determine the physical and mechanical parameters of the initial dam body, tailings accumulation body and dam foundation rock and soil layer of the tailings pond through rock and soil tests: what needs to be explained is that the main physical and mechanical parameters Including: the effective internal friction angle φ of the soil, the effective cohesion c of the soil, and the natural weight γ of the soil; at the same time, the position of the pore water pressure gauge on the dam slope of the tailings reservoir is selected, and the monitoring plan is compiled according to the field survey results.

[0043] Step 2: Determine the monitoring scope of the tailings pond ac...

Abstract

The invention discloses a tailing pond dam slope anti-sliding stability analysis method based on a Sweden slice method, and the method comprises the following steps: geological exploration of a tailing pond dam slope site: determining a tailing dam range according to the site geological exploration; determining physical and mechanical parameters of a dam body, a tailing accumulation body and a dam foundation rock soil layer soil body in the initial stage of the tailing pond through a rock and soil test; monitoring the seepage line of the dam slope of the tailing pond in real time; calculating the anti-sliding stability coefficient of the tailing pond dam slope; and carrying out the real-time early warning of tailing pond dam breakage. Through geological exploration of the tailing dam, physical and mechanical parameters of an initial dam body of the tailing pond, a tailing accumulation body and a dam bed rock soil layer soil body are combined with real-time dam body infiltration line monitoring data, and on the basis of a Sweden slice method theory and a landslide stability analysis method theory, a direct index of the anti-sliding stability coefficient of the dam slope of the tailing pond is further calculated to realize forecasting and early warning of the tailing pond.

Description

technical field [0001] The invention relates to the technical field of tailings dams, in particular to a method for analyzing the anti-sliding stability of tailings dam slopes based on the Swedish slice method. Background technique [0002] Tailings pond refers to the place where dams are built to intercept valley mouths or enclosures, and are used to store metal or non-metallic mines for ore sorting and then discharge tailings or other industrial waste. Tailings pond is a man-made debris flow with high potential energy. Hazardous source, there is a danger of dam failure, and once the accident occurs, it is easy to cause serious and extraordinarily serious accidents. [0003] Whether it is from the perspective of protecting the ecological environment or ensuring the safety of public life and property, it is of great significance to study and analyze the stabilization process of tailings ponds. However, the current anti-sliding stability analysis of the tailings dam slope on...
