The deepening of marble quarries with rich CaCO3 based marble reserves in Turkey brings along multiple problems. The steep and high slopes due to deep open pit geometry, the transportation distance within the pit, problems in transportation, narrowing down the active working area while going deeper and complexity in organization are just a few of the mentioned problems. The room and pillar method -an underground mining method- with ease of production and transportation is set in motion in marble quarries to resolve the problems encountered in deep open pit mining and the difficulties of selective production due to the pit geometry. A limestone quarry in Antalya-Finike vicinity in southern Turkey applying both open pit and room and pillar methods is investigated by numerical modeling and empirical formulas. The realized situation is interpreted and compared to the data gathered by empirical formulas and the results of numerical analysis. The necessity to resize the pillars is revealed as a result of field works, laboratory and modeling studies in the light of the geometry and observed deformations in room ceilings and pillars.
