Abstract


Sebagian besar eksploitasi batubara menggunakan sistem open pit, yang akan membentuk suatu cekungan. Cekungan hasil dari eksploitas mempunyai lereng. Kestabilan dari lereng pembentuk cekungan sangat penting karena menyangkut keselamat pekerja, alat, serta kelancaran produksi. Penelitian ini dilakukan untuk melakukan analisa stabilitas pada lereng tambang dengan menggunakan metode Bishope dan Metode Spencer. Analisa stabilitas dilakukan pada 7 model geometri. Dari ketujuh model masing-masing mempunyai nilai faktor keamanan dengan menggunakan metode bishop 0.643, 0.669, 1.086, 0.862, 1.58, 1.184, dan 1.428. Nilai faktor keamanan dengan menggunakan metode spencer masing-masing 0.653, 0.695, 1.113, 0.893, 1.602, 1.208, dan 1.446
