Mining activities date back to ancient ages in Eastern Black Sea Region. Mine wastes after smelting can be encountered in many parts of the region. The region has quite a high number of metallic ore reserves and therefore, the majority of these wastes come from metal mining. In addition to the old entries found at the region, there are new entries constructed for exploration/production purposes. After closure of mines or terminating exploration work, these entries are not left taking necessary safety measures and this may cause serious injuries and even deaths. Based on an event causing a death of a university student, this paper investigates the risks found in the abandoned mine entries and discusses the measures to take when entering to these entries for different purposes (investigation, sampling, rescuing etc.).
