Brze promene u okruženju pred rukovodioce postavljaju mnogobrojne zahteve, pre svega, one koji se tiču ostvarenja ciljeva u zadatom vremenu i raspoloživim sredstvima što zahteva fleksibilan pristup u organizovanju aktivnosti i efikasnost u njihovom sprovođenju. Upravljanje projektima, bilo koje vrste, suštinski, predstavlja veoma složen proces odlučivanja uslovljen velikim brojem ulaznih faktora. Ti faktori treba da omoguće fokusiranje na prioritete i ciljeve, praćenje realizacije, fleksibilnost u prevazilaženju teškoća, prilagođavanje promenama, te kontrolu nad ostvarenim rezultatima. Ovakav način upravljanja zahteva korišćenje proverenih tehnika i alata te timski rad angažovanih na projektu, kako bi se rezultati postigli u planiranom vremenu i sa planiranim sredstvima. Odgovor na ova pitanja su preko svojih metodologija pokušali da daju mnogi autori, poznati svetski instituti za upravljanje projektima, među kojima je i PMI (Project management Institute USA), čije preporuke i smernice su, u značajnoj meri, poslužile kod izrade ove disertacije. U savremenom dobu površinska eksploatacija ležišta mineralnih sirovina, usled velikog broja nepoznanica, obavlja se u sve složenijim uslovima, koje sa aspekta projektovanja, planiranja i pripreme za eksploataciju, te samog procesa odvijanja eksploatacije predstavljaju ograničavajuće faktore. Kada je reč o površinskoj eksploataciji uglja, usled niza specifičnosti koje je odlikuju, navedena problematika postaje još izraženija. Po pravilu, realizacija projekata ovog tipa, predstavlja vrlo složen proces sastavljen od višedimenzionalnih aktivnosti ispitivanja svih relevantnih determinanti budućih stanja i promena koje projekat nosi sa sobom. Sa druge strane, razvoj i nova saznanja u drugim naučnim oblastima na koje se oslanja rudarska nauka, pružaju sve šire mogućnosti njene primene.

Rapid changes in the environment set numerous requirements before the managers. The aforementioned requirements are primarily related to the achievement of objectives within the given time and resources available, which requires a flexible approach to organisation of activities and efficiency in their implementation. Project management of any kind, is essentially a very complex decision-making process conditioned by a large number of input factors. Such factors should allow to focus onto the priorities and objectives, to monitor the implementation, provide flexibility in overcoming any difficulties, enable adaptation to changes and provide control over the results obtained. This management method requires the use of proven techniques and tools, as well as of teamwork involved in the project in order to achieve the results within the planned time and by using planned resources. The answer to these questions was sought and given, via various methodologies, by many authors, world-renowned project management institutes, including the PMI (Project Management Institute, USA), whose recommendations and guidelines have been used, to a significant degree, in the preparation of this dissertation. In modern times, surface mining of mineral deposits, due to the large number of unknowns, is performed in increasingly complex conditions which in terms of design, planning, mining preparation and the mining process represent the limiting factors. When it comes to surface coal mining, due to a number of specific features characterising it, the above problems become even more pronounced. As a rule, the implementation of such projects is a very complex process consisting of multidimentional testing activities of all relevant determinants of future conditions and changes that the project entails. On the other hand, the development and new knowledge in other scientific areas the mining science relies on, provide continuously expanding possibilities of its application. Taking all theabove into account, the standard approach of project management cannot fully provide for all the complexity of mining projects. Therefore, it is required...
