Abstract
Analysis and risk assessment of the supply of copper ore in the belt conveyor system in an underground mine
Highlights
There has been a clear increase in the interest of manufacturing enterprises in risk management due to the successive increase in the economic risk and the introduction of risk management to many management standards
The issue of risk management appears in the context of risk assessment and reliability of machine systems and transport systems in mining (Andrejiova et al, 2015; 2020; Blazej& Jurdziak, 2017;Blokus-Roszkowska & Kolowrocki, 2015; Czaplicki, 2008; Czaplicki, 2009; Dhillon, 2017; Tworek et al 2018)
In copper ore mines having no market sales problems, any downtime in the transport system can lead to production losses that cannot be overcome at a later date
Summary
There has been a clear increase in the interest of manufacturing enterprises in risk management due to the successive increase in the economic risk and the introduction of risk management to many management standards. An example here may be the ISO standards used in most manufacturing companies, such as ISO 9001, ISO 14001, ISO 45001, ISO /IEC 27001, ISO 23301, IATF 16949, ISO 22000, ISO 17025 and others, which includes aspects of risk management. The lack of downtime serves to minimize the unit costs of extraction, which are higher in underground mines than open-pit ones. Reducing production increases costs by making competition conditions even worse (Więcek et al, 2020). Downtime costs increase the optimal cut-off grade (Kržanović et al, 2015), which reduces the resources that are profitable for extraction
