Embodiment 1

[0207] Example 1: The non-coal mining industry selected 33 tailing ponds as assessment objects; through the risk identification of the 33 tailing ponds, the risk severity (inherent risk) of dam failure risk points was assessed.

[0208] The initial realistic risk assessment results of 33 tailings pond dam break accident risk points are shown in Table 1, and the names of tailings ponds in Table 1 are indicated by numbers.

[0209] Table 1 Initial realistic risk assessment of 33 tailings pond dam failure accident risk points

[0210]

[0211] In the assessment of 33 tailings dams, the high-risk facility index hs of 10 tailings dams reached 1.70, because the dams used "wet discharge upstream tailings dams", and the stability of the dams was relatively poor; 1 tailings dam The high-risk facility index hs of the reservoir is 1, because it adopts a one-time dam construction method, and the storage material is phosphogypsum, so the dam body has high stability.

[0212] The material...

Embodiment 2

[0216] Example 2: The hydrogenation reaction of the C9 hydrogenation device of a hazardous chemical company is a "hydrogenation process"; C5 resin device, carbon

[0217] The polymerization process of the nine-cold polymer resin and C5-C9 copolymer resin plant belongs to the "polymerization process"; based on the characteristics of the company's system, based on the identification and analysis of dangerous and harmful factors, the polymerization process, hydrogenation process and storage tank The area is evaluated as the unit of the whole system; the carbon five resin process unit is the evaluation object.

[0218] Taking the evaluation object of carbon five resin process equipment, three risk points such as fire accidents, explosion accidents, and poisoning accidents are evaluated as the focus of identification and evaluation of high-risk inherent risks:

[0219] a) Fire accident risk point h 1 =1.3×5×3×1.01×1.45=28.56;

[0220] b) Explosion accident risk point h 2 =1.3×5×...

Embodiment 3

[0231] Example 3: Taking the ironmaking of a certain metal smelting enterprise as the unit of the system for evaluation.

[0232] The four risk points of blast furnace collapse accident, molten metal accident, gas accident, and powder explosion accident are taken as the focus of identification and assessment of high-risk inherent risks.

[0233] at 2600m 3 The new 1# blast furnace is used as the calculation object to evaluate each risk point.

[0234] The new 1# blast furnace is currently running smoothly, with a high level of intrinsic safety, and various safety interlocks are normally put into use. The value is assigned according to "error safety", and hs = 1.3.

[0235] There are two high-risk processes in blast furnace collapse accident risk points: soft water closed circulation system and blast furnace system. Among them, the eigenvalues ​​of the soft water closed circulation system are the water flow monitoring failure rate of the cooling stave system and the water flo...

Abstract

The invention discloses a major safety risk index measurement model. The major safety risk index measurement model includes unit inherent danger index metering, unit risk management and control index metering and unit dynamic index metering. The metering of the unit inherent danger index is a place personnel exposure index weighted accumulated value of the inherent danger indexes of a plurality of risk points; the initial high-risk risk management and control frequency of the unit and the inherent risk index of the unit are aggregated to obtain an initial high-risk safety risk value of the unit; the unit dynamic index metering comprises high risk monitoring characteristic index metering, safety production basic management dynamic index metering, special period index metering, high risk Internet of Things index metering and natural environment correction index metering; and the unit initial high-risk-safety risk value is corrected by using the unit dynamic index metering value to obtain a unit real risk value. According to the invention, the combination of the inherent risk and the risk management and control probability can be presented, and decision support can be provided for restraining major accidents.

Description

technical field [0001] The invention belongs to the technical field of safety risk assessment, and in particular relates to a major safety risk index measurement model. Background technique [0002] All systems are in motion, and the motion of the system is the result of the contradictions and struggles in the system; this is a universal principle in the universe, and the security system also obeys this principle. [0003] Although the structure of the safety system is complex, it can be summarized as the result of the interaction of two basic contradictions, namely "danger" and "danger prevention and control". [0004] According to the large-scale system theory, the output variable is transformed into the annual casualty index Y(k) by adopting the variable aggregation method, and the input variable is assembled into two variables with different signs, the "risk" index H(k) and the "risk prevention and control" index C(k). [0005] Y(k)=(1-C(k))Y(k-1)+H(k). [0006] Safet...
