Opis:
As the major industries, mining has high potential risk of accidents. Historically minerals have supported humane development and civilization but at the same time this industry has been accompanied by accidents, often with disastrous consequences. Number of mine accidents worldwide, as well as in the Stan Terg mine is disturbing, even more disturbing is the fact of the repetition of the causes of mining accidents. This investigation aims to analyze the causes of accidents, tending to provide the accidents prevision through risk assessment. For this purposes various data and documents, related to accidents in the Stan Terg mine have been analyzed, as well as international documents and statistics related on mining safety and accidents. Whereas, the time period of 2007–2011 is analyzed as a key study, 306 accidents have been analyzed for this purpose. Accident causes, date and time, accident location, working shift, worker’s age and type of injury have been analyzed for each selected accident. Thus, for this period of time are caused 292 minor injuries, 14 serious injuries and 1 fatality accident, 60–70% of accidents are caused in the production process, 25–35 in the maintenance process, whereas about 2–5% during of monitoring or other types of works.

Opis:
In this paper, preliminary support design of the main underground opening (i.e., mine adit) located at the Artana lead-zinc mine, Kosovo, was examined by employing both conventional and numerical methods for safe underground excavation and design. In order to conduct field studies including discontinuity surveying and sampling for laboratory testing two empirical methods, namely rock mass rating (RMR) and geological strength index (GSI) were employed. For the purpose of determining necessary support units RMR system was utilized. However, these kind of systems can take into account for neither the depth of underground opening nor in situ field stresses. For this reason, empirical design methods (i.e., RMR system) failed to investigate the performance of rock support units; therefore, a 2D finite element analysis program was used to assess the performance of the proposed support systems. This indicated that RMR system might not be applicable for poor and very poor rock masses located in deep environment (i.e., 300 and 400 m). Moreover, this is linked to the fact that the RMR system does not consider in situ stress conditions. This study showed that when empirical methods are supported by numerical analysis, the preliminary support system design will be much more reliable.
