Abstract
(not available in English)
Designing a mine using room and pillar mining method (R&P) represents complicated task. Choosing the dimensions of pillar is a very sensitive subject, since it is directly connected with room stability and exploitation factor of ore body, because some part of ore body stays in pillars. This paper will compare multiple ways to correctly calculate dimensions of pillar and rooms, so that room stability wouldn't be endangered and, at the same time, to excavate as much ore body as possible, to enhance efficiency.
