ABSTRACT
This paper describes the conceptual solution of the room-and-pillar excavation method with ore shrinking in the »Biochki stan« mine in Niksic, FRY.
Trial excavation by this method is about to prove the possibility of the recovery increasing from 60–65%, which is now, to 75–80%. This is also basic interest for introduction of this method.
Such recovery increasing is possible to reach not just by introduction of the new excavation method, but it is also necessary to accept other new technologies, such as roof rock bolting technology.
Accepting of the rock bolting technology is the most important phase in the introduction of the mentioned excavation method.
