description | In the open pit mine planning, in addition to mineral reserves factors, mining technical, economic, environmental and geoteknical factors includid slope stability is an important factor in open pit mining operations. Mine slope stability is determined by the geotechnical conditions, coulrius: the physical and mechanical properties of rocks, soil and water level conditions in the form of geomorpholosy, discontinuities, rock mass structure, etc. design the open pit slope geometry must be well informed on the geotechnical and geological to aspeakan needed to underslood that can be predicted slope, slope height and width of a stable bench for mining activities. Accident that causes by open pit slope instability will have an impact on occupational safety and health, equipment, companies and the environment that could cause harm to the company and hinder the process of mineral production. This study aims to assess the open pit slope stability by using the optimum approach to the study of geotechnical rock mass classification method based on RMR with 5 parameters: uniaxial compressive strength, RQD, spacing field discontinuities ( spacing stocky ), condition of discontinuities and groundwater conditions.
To find the slope angle used hubunganan RMR value with a slope angle are suggested by SMR . Testing of physical and mechanical properties of rocks in the form of the physical properties of the test to get the parameter index properties and mechanical properties test a uniaxial compressive strength test to get the parameters of rock compressive strength, direct shear tests to obtain parameters of cohesion, friction angle in both peak and residual as input data in slope stability analysis by using the numerical limit equilibrium method that can show the value of the slope angle, slope height, width bench and the value of the safety factor of the slope .
The results recommend that the slope angle based on RMR and SMR classification methods and numerical analysis method for single slope is GT - MT - 03 with 75o slope angle, slope height of 20 m with FK 1,304 . GT - MT - 06 with 65o slope angle, slope height of 15 m with FK 1.366 and for the GT - 08 MT � 65o slope angle, slope height of 20 m with FK 1,347. Overall slope recommendation for open pit mine plan at Mutiara Bukit Suharto block is 60 m high overall slope, slope angle 65o, bench width of 20 m with a single high slopes that form the overall slope of 15 m with a safety factor ( FK ) between 1,520 and 1,713. |
