Coal dust explosions (CDE) are one of the main threats to the occupational safety of coal miners. Aiming to identify and assess the risk of CDE, this paper proposes a novel method of fuzzy fault tree analysis combined with the Visual Basic (VB) program. In this methodology, various potential causes of the CDE are identified and a CDE fault tree is constructed. To overcome drawbacks from the lack of exact probability data for the basic events, fuzzy set theory is employed and the probability data of each basic event is treated as intuitionistic trapezoidal fuzzy numbers. In addition, a new approach for calculating the weighting of each expert is also introduced in this paper to reduce the error during the expert elicitation process. Specifically, an in-depth quantitative analysis of the fuzzy fault tree, such as the importance measure of the basic events and the cut sets, and the CDE occurrence probability is given to assess the explosion risk and acquire more details of the CDE. The VB program is applied to simplify the analysis process. A case study and analysis is provided to illustrate the effectiveness of this proposed method, and some suggestions are given to take preventive measures in advance and avoid CDE accidents.

“…The pressure relief device or emergency venting system must be suitable to relieve the flow capacity required for the largest single contingency or any reasonable and probable combination of incidents. This parameter, the treatment of discharges, is identified as an active method in the design phase by Prugh (1992) and as a relevant protection measure by experts Argyropoulos et al (2012), Wang et al (2013). The venting requirements provided in the API standard (API, 1998) are based on studies of hexane stored in steel tanks.…”

Abstract. Fire around storage tanks for petroleum products can have disastrous consequences for the environment and the population. These fires, due to accident or arson, are very well managed by security divisions but, nevertheless, involve the release of an amount of vapour from the petroleum present in the storage device. The exposure of a non-refrigerated aboveground liquid petroleum or petroleum product storage tank to fire can also lead to internal overpressure. PV-valves ensure that the normal and emergency venting requirements are satisfied, and determination of such requirements is key for the safety of petroleum tanks and should not be underestimated. This paper presents and discusses some methods that can be used to evaluate the vapour flow. In the aim of finding an exact answer rapidly, a thermal analytical approach is first investigated, which reveals the complexity of the solution. Thus, a numerical approach, based on finite-volume description, is used to set the first steps of the flow assessment. Based on a thermodynamic hypothesis, a simplified method is finally put forward for the evaluation of the amount of vapour released. The algorithm used to determine how temperature, pressure and flow evolve over time, which is very useful information for the safety of these devices, is then detailed and the results discussed.

“…However, in traditional FTA, the failure probabilities of the basic events (BEs) are expressed by exact values, has been found to be inadequate to deal with these challenges mentioned above. And this makes quantitative analysis of a fault tree of a system questionable by conventional methods [3]. In order to handle subjective factors and nonlinear characteristics, inherent in the importance identification for a fault tree in the reliability analysis, many conscientious researchers have taken the fuzzy uncertain situations into consideration.…”
