Embodiment Construction

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

[0028] A method for assessing the risk of a tailings pond dam failure, comprising the following steps:

[0029] Step 1, construct the evaluation factor set F={f 1 , f 2 , f 3 ,... f n}, f i Represents the i-th factor; the evaluation factor set F includes the overflow f 1 , instability and collapse f 2 , seepage damage f 3 , structural damage f 4 and security infrastructure management f 5 Five evaluation factors.

[0030] According to the statistical analysis of tailings pond accidents at home and abroad and the structure of the tailings pond itself, the tailings pond dam failure risk index system is divided into five first-level indicators: flooding collapse, instability collapse, seepage damage, structural damage, and safety foundation management. , and 22 secondary indicators such as accumulation capacity, flood control standard, and capacit...

Abstract

The invention discloses a tailing pond dam break risk evaluating method comprising the following steps: building an evaluating factor set F=(f1, f2, f3,..fn), wherein fi refers to i factor; building a comment rate set U corresponding to each evaluating factor in the evaluating factor set F, determining the weight of each evaluating factor S=(S2, S2, S3,..Sn), wherein Si refers to the weight of fi; obtaining comment rates of each evaluating factor from the comment rate set U, and obtaining a fuzzy determination matrix Ri; obtaining tailing pond risk each factor evaluating matrix Zi=SiRi, building a tailing pond risk evaluation matrix (see formula) according to the tailing pond risk each factor evaluating matrix Zi; carrying out secondary fuzzy integration evaluation C=SZ, and obtaining ck=max(cj) according to the maximum membership principle, so an evaluated object belongs to k rate.

Description

technical field [0001] The invention belongs to the technical field of tailings pond safety, and in particular relates to a method for assessing the risk of a tailings pond dam break. Background technique [0002] Tailings pond is an important production facility in mining engineering, and it is also a major source of danger in the production management of mining enterprises. Dam failure is a direct manifestation of tailings pond safety accidents. With the frequent occurrence of tailings pond safety accidents at home and abroad in recent years, it is particularly important to strengthen the safety monitoring and management of tailings ponds, and the risk assessment of tailings pond dam breaks has important practical significance for the safety monitoring and management of tailings ponds. [0003] At present, relevant experts and scholars have conducted a lot of research and exploration on the risk assessment of tailings pond dam failure. Zheng Xin et al. applied the set pai...
