Abstract

The limestone mine activity needs a good mine plan design with the result that saved for the environment. Mine design is determined by rock mass quality. The rock mass quality in each mine location is different and that is influenced by the geological conditions. Research area is located in limestone quarry Sawir Block of Kerek District, Tuban Regency, East Java Province. In limestone quarry area, there is cavity zone which consists cavity limestone layer at the wall of quarry bench. This cavity layer in limestone quarry has occurred by solution process. The cavity layer zone has more potential as weak zone which caused failure of bench in limestone quarry area. To analyze of the research of rock mass quality in cavity limestone layer using Geological Strength Index (GSI) system. Final result of the research is rock mass characterization specifically for cavity limestone layer.

Abstract

The research area is a limestone quarry region prospect, located in Gunung Sudo, Gunung KidulRegency, Special Region of Yogyakarta Province. Safety factor of bench in limestone quarry isextremely determined by rock mass quality. The aim of this research is analyzing of rock massstrength of limestone in the quarry prospect using the Hoek-Brown failure criterion. The researchused quantitative method. To obtain rock mass strength analysis of limestone needs someparameters. The main parameters are uniaxial compressive strength of intact rock, GSI, lithology,disturbance factor, unit weight and application for slope (height). To solve this analysis is assisted byRoclab software. The Roclab is a software program for determining rock mass strength parametersbased on the generalized Hoek-Brown failure criterion. Final result of the research will be used forsafely mine design of the limestone quarry.
