Abstract

The invention discloses a tailing pond layered index safety assessment and early-warning method and system. The method comprises the steps that a three-level safety index system is built, wherein the three-level safety index system comprises four second-level indexes which are the stockpiling system, a drainage system, a risk system and a management system and fifteen three-level indexes which are the pond water level, the rainfall capacity and the like; a tailing pond safety assessment model is built, and the safety index system is utilized for assessing the overall safety state of a tailing pond; a tailing pond safety early-warning model is built, and early-warning judgment is carried out; the safety early-warning model comprehensively figures out a dynamic change curve of the future pond water level in the flood season by means of data collected in real time and weather forecast information transmitted by the network, the data collected in real time and measured by the safety assessment model to carry out comprehensive safety assessment and evaluation on the tailing pond, dangerous trend classification is carried out according to assessment, then the classification information is put into a pond water level-dam break model, the dam break risk is comprehensively calculated according to the classification information and a predicted pond water level value, and early-warning judgment is carried out according to the risk. The early-warning effect is accurate, reasonable and comprehensive.

Description

technical field

[0001] The invention relates to the field of safety system engineering, in particular to a method and system for safety evaluation and early warning of layered indicators of tailing ponds. Background technique

[0002] As a place to store metal or non-metal mine industrial waste residues, it is a necessary facility to maintain the normal production of metal mines. Tailings ponds are a major source of danger for man-made debris flows with high potential energy. Once a dam breaks, it will endanger the lives and property safety of downstream residents and The environment poses a serious threat. In recent years, with the rapid development of industry, the number of tailings ponds at home and abroad has increased dramatically. With the frequent occurrence of dam failure accidents, the safety assessment and early warning of tailings ponds is an urgent problem to be solved.

[0003] At present, there is no unified standard and specification for the method and syste...

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0028] There are many factors affecting the safety of the tailings pond, which is a nonlinear complex system. Due to the nonlinear, time-varying and random interference factors of the research object, for this uncertain system, it is proposed to use the fuzzy logic system to establish a fuzzy approximation model of the controlled object. On this basis, the appropriate control law is designed to determine the stability of the chaotic state, so as to carry out the corresponding security assessment.

[0029] Such as figure 1 As shown, the assessment and prediction of tailings ponds is determined as a three-level system after research, and the first-level index is the safety of tailings ponds itself, which is divided into four levels: safe, relatively safe, relatively dangerous, and dangerous, and the second-level indicators that affect its safety , The third...
