    2020-1-8  The underground mining becomes a preferable alternative regarding the increasing production capacity, increasing transportation cost due to deepening open pits, necessity of selective production and occurrence of waste problems. This alternative brings the necessity of determining the room and pillar mining method parameters for a limestone quarry in Beydaglari Autochthonous located in south-western Turkey. The observed roof cracks and rock falls create a risky condition in the currently operating limestone quarry, planned and initiated quarrying without any modelling studies in advance.
