Embodiment Construction

[0105] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0106] A method for analyzing and predicting the environmental stability of decommissioned uranium tailings ponds based on uncertainty theory, including environmental stability analysis and environmental stability prediction.

[0107] Step one, environmental stability analysis.

[0108] 1) The establishment of an indicator system for the environmental stability of uranium tailings ponds;

[0109] The environmental pollutants in the uranium tailings pond mainly migrate through the flow of water and the diffusion of the atmosphere, affecting the surrounding ponds, the Xiangjiang River system, soil and the atmosphere. According to the principal component analysis and related methods, the main indicators affecting the environment are obtained, combined with For the actual situation of uranium tailings, twelve environmental impact indicators were...

Abstract

The present invention discloses a retired uranium tailing impoundment environment stability analysis and prediction method based on an uncertainty theory. Stability analysis comprises establishment of a uranium tailing impoundment environment stability index system, calculation of each index stable interval, and analysis of an environment stability of each dam section of a uranium tailing impoundment; and environment stability prediction comprises prediction on time required for converting to an unstable state from a stable state, and prediction on time required for converting to the stable state from the unstable state. The stable intervals of main environment pollution indexes of the uranium tailing impoundment are obtained, the environment stabilities of the uranium tailing impoundment at different time points are calculated, and the fuzzy conception of the uranium tailing impoundment environment stability is defined by the accurate mathematical language, so that organic combination of qualitative analysis and quantitative calculation on the uranium tailing impoundment environment stability is implemented and the theoretical basis is provided for safety management and decision analysis on the retired uranium tailing impoundment.

Description

technical field [0001] The invention belongs to the technical field of energy and information processing, and relates to a method for analyzing and predicting the environmental stability of decommissioned uranium tailing ponds based on uncertainty theory. Background technique [0002] With the demand for energy in our country, a large amount of uranium tailings and waste rocks will be produced, and the potential safety problems of the uranium tailings ponds for storing uranium tailings and waste rocks on the environment and the public are very prominent (uranium tailings ponds refer to Dams are built to intercept valley mouths or enclosures, and are used to store uranium ore waste rocks and tailings). Although the surrounding environmental quality and ecological status have been significantly improved after decommissioning and treatment, because the radionuclides and other chemical toxic elements still diffuse and migrate through various channels for a long time after coveri...
