Analisis Kestabilan Lereng Highwall Pit Timur PT.Ciptakridatama Jobsite PT.Kuansing Inti Makmur ,Kecamatan Tanjujuhan ,Kabupaten Bungo, Provinsi Jambi.

PT Cipta Kridatama Jobsite PT Kuansing Inti Makmur conducts mining using the open pit mining methode. Slope stability is an important factor, because it involves issues of human safety (workers), equipment safety, and smooth production. The level of stability of the mine slope itself can be known after conducting geotechnical investigations which include geotechnical drillng, testing the physical and mechanical properties of rocks, including density, cohesion and phi. Based on the slope stability analysis using the Bishop method on the actual geometry for section A-A’, B-B’, C-C’, D-D’, E-E’, F-F’, the safty values ranged for single slope 0,74 to 3,61 and for the overall slope 1,95 to 3,75. So that the geometry changes are made on the cross-section A-A’, B-B’, C-C’, F-F’ and the safty factor value for the single slope ranges from 1,29 to 1,43 and the overall slope is 1,97 to 3,19. Stable slope conditions can increase the minimization of work accidents.Keywords : slope stability, bishop, single slope, overall slope, recommendation
