Abstract
One of the most hazardous fields of engineering is mining operations and accordingly, it requires extra consideration on risk evaluation. Decorative stone quarrying is one of the main branches of the mining industry in Iran. Currently, Iran, China and Italy are known as the three main producers of decorative stones in the world. Subsequently, risk assessment is one of the main steps of quarrying organization. One of the main steps of risk assessment is Risk Breakdown Structure (RBS). In order to achieve this goal, a comprehensive structure of dimensional stone quarrying is modelled in this re- search and divided into 17 main levels. One of the most useful procedures of risk ranking is Multi attribute decision- making methods which state that they have numerous affecting parameters. In the next step of this study, the main hazards of main decorative stone quarrying are assessed by implementing the ‘Preference Ranking Organization Method for Enrichment Evaluation’ (PROMETHEE) technique. As a final point, Economical, Management, and Schedule risks are determined as the most intimidating hazards in this field.
Highlights
Risk is an uncertainty, occurrence or condition and its existence has different effects on the aims of the operation, e.g. including threats and opportunities for the project goals (Pinto, 1998)
Research in mining operations are dramatically influenced by dangers and any decision needs risk aspects
The opinions of 21 decorative stone experts were gathered for filling the initial decision matrix accurately
Summary
Occurrence or condition and its existence has different effects on the aims of the operation, e.g. including threats and opportunities for the project goals (Pinto, 1998). For risk assessment in underground projects (tunnels and excavations) in this research, a regression model and probability-consequence matrix are used for processing all risks (Reilly and Brown, 2004; Reilly and Parker, 2007). Safety factors for decorative stone quarries were examined for the first time through an analysis of different incidents and injuries which occurred For this purpose, standard guides were implemented for safety, quality measurement and risk analysis (Bagherpour et al, 2015). A classification of quarries considering safety and environmental attributes help mining companies in all aspects of health, safety and environmental management. This process helps them to convert their qualitative assessment to quantitative evaluation and reliable judgment (Yari et al, 2016). Using the PROMETHEE method, all the defined hazards concerning the imposing aspects were evaluated and the most threatening risks were determined for the Ghasre dasht mine (Yari et al, 2014)
