Tailing pond major safety risk quantification method

Abstract

The invention discloses a tailing pond major safety risk quantification method. The method comprises the following steps: S1, identifying unit risks, and forming a unit security risk and hidden danger violation electronic evidence database; S2, dividing a safety evaluation unit of the inherent risk characteristics of the tailings pond into a dam body unit, a flood drainage unit, an auxiliary facility unit and a surrounding environment unit; S3, carrying out the quantitative measurement of inherent risk indexes of risk points; S4, taking a weighted accumulated value of the place personnel exposure indexes of the inherent risk indexes of the plurality of risk points as a unit inherent risk index H; S5, taking the reciprocal of the unit safety production standardization score percentage as a unit risk frequency index; S6, aggregating the initial high-risk risk management and control frequency of the unit and the inherent risk index of the unit; S7, correcting the initial high-risk safety risk value of the unit by adopting a real risk dynamic correction index. The method aims at improving the intrinsic safety degree and safety management level of the tailings pond enterprises, preventing major and extra-major accidents and reducing accident harm consequences, and provides technical guidance for safety risk management and control of the tailings pond enterprises.

Description

technical field [0001] The invention belongs to the technical field of enterprise safety risk quantification, and in particular relates to a method for quantifying major safety risks of tailing ponds. Background technique [0002] Tailings reservoir plays a very important role in mine production and is an important facility to maintain mine production. All countries in the world attach great importance to the safety of tailings ponds because once accidents such as landslides, mudslides and dam failures occur in tailings ponds, casualties and property losses will be caused. [0003] Gobla has studied the risks posed by the uncontrolled release of tailings dam impoundments, arguing that stagnant water and high water content waste at mining and industrial processing sites could pose a threat to public safety and the environment. Risk assessments for conventional dams have moved from qualitative screening to Methods evolve into quantitative analysis tools. [0004] Salueiro et...

AI Technical Summary

Problems solved by technology

Most of the previous studies analyzed and evaluated the risk factors of dam failure in the operation stage, or only identified the risk indicators in each stage of the life cycle, and failed to conduct more in-depth risk evaluation and control research.

[0009] (2) The identification of risk factors for tailings ponds is basically at the stage of qualitative research and theoretical analysis, that is, the risks of tailings ponds are directly listed through theoretical analysis, and there is a lack of empirical testing of these factors

[0010] (3) There are many static-based risk assessments and few studies on dynamic risk assessments. Therefore, it is of great significance to carry out quantitative research on the safety risk of tailings dam failure
