Abstract

The major objective of this study was to design and analyze the stability of underground room and pillar mine for Istanbul-Yenikoy coal field. Preventing pillar failure and minimizing surface subsidence was the primary goal. A preliminary design is carried out by using tributary area theory. Preliminary design is tested by finite element analysis. In finite element analysis, not only the structural behavior of pillars, and roof and floor are simulated, but the interaction among them are also taken into consideration.
