Ítem Caracterización geológica y geomecánica de la mina San Joaquín, para el diseño de explotación por el método de cámaras y pilares. Carbones San Fernando S.A.S. Concesión 11338(Universidad EAFIT, 2018) Cañas Gaviria, María Camila; Marín Cerón, María Isabel; Piragauta Aguilar, Jaime AlbertoThe main objective of this project was the geological and geomechanical characterization of the San Joaquín mine, with the aim of designing a different exploitation method that leads to diminish, avoid or mitigate the subsidence phenomenon; It also has a relationship between a recovery rate and a high safety factor that allows a safe and economically feasible extraction of the mineral -- The fundamental basis of the studies consists of the description and analysis of the physical and mechanical properties of the rock mass by collecting geological and geotechnical information from simple compression tests that allows to identify and characterize the resistance of the coal beds and the roof rock, obtaining as a final result the construction of a geological and geomechanical model that determines the behavior of the rock mass in front of the vertical efforts generated by mining work, since all the ideal dimensions for the design of the exploitation by means of the method rooms and pillarsÍtem Hulleras de la República de Colombia en la Costa Atlántica(Imprenta de Vapor de Zalamea Hermanos, 1890)
