632 Possibilities for Optimization of Reliability and Maintenance in Mining Operations based on Experience in Nuclear Industry Dragan Komljenovic 1) , Jacek Paraszczak 2) and Vladislav Kecojevic 3) Abstract This paper discusses possibilities of technology and knowledge transfer from the Nuclear industry to Mining Operations in the field of Reliability and Maintenance. Both industries face important challenges with regard to safety, productivity and environment. The Nuclear Industry has achieved significant levels of productivity while remaining safe through a systematic approach using accumulated knowledge and developing industry tailored Reliability and Maintenance Processes. Some examples of their potential application in mining have been given. The paper presents also some indications and suggestions concerning further research work in this field.
