Abstract
The National Mining System is one of the most important national systems because it provides the necessary coal (anthracite, hard coal, lignite, peat, etc.) to ensure the energy security of Romania, as well as fuel for the steel and cement industry. But as any national system is not one hundred percent secure, it is subject to elements of instability and insecurity that are quantified in dysfunctions, deficiencies and nonconformities, which are in fact the main sources of undesirable events with an insecurity effect. These system elements, dysfunctions, deficiencies and non-conformities, are the main sources of vulnerability generation, which can have disastrous effects that can cause energy and national crises. In this paper, the authors identified, defined and propagated all the systemic elements of instability and insecurity within the National Mining System.
