Dengan kejadian kelongsoran yang pada penampang Y-Y’ low wall elevasi +74 ke +62 di area pit MTBU PT. Bukit Asam Tbk, maka perlu dilakukan kajian geoteknik agar rencana penambangan dapat didukung dengan data yang akurat terutama dalam hal kemantapan lereng. Untuk mendapatkan rekomendasi geometri optimum, serta faktor keamanan (FK) yang sesuai dengan perencanaan, diperoleh data awal Silty Claystone: Bobot isi (γ) = 22,19 kN/m3, kohesi (c') = 28,14 kN/m2 dan sudut geser dalam (ϕ') = 33,30°. Silty Sandstone: bobot isi (γ) = 20,36 kN/m3, kohesi (c') = 26,38 kN/m2 dan sudut geser dalam (ϕ') = 25,50°. Sandy Silt: Bobot isi (γ)= 19,67 kN/m3, kohesi (c') = 32,16 kN/m2 dan sudut geser dalam (ϕ') = 39,11°. Geometri lereng rekomendasi: 1. Metode Morgenstren-Price berdasarkan hasil desain menggunakan program Geostudio Slope/W 2007, maka untuk setiap penampang baik single slope maupun overall slope faktor keamanan ≥ 1,25 yang berarti dalam keadaan stabil atau aman. 2. Metode Hoek and Bray, 1981 dilakukan percobaan analisis balik lereng single slope high wall elevasi +74 ke +62 pada saat terjadi longsor menggunakan input properties material. Setelah dilakukan analisis kestabilan lereng dengan parameter analisis balik Hoek &amp; Bray (FK = 0,99), didapatkan nilai (FK = 0,919). Dalam kondisi jenuh diperlukan penanganan membuat lereng tersebut lebih landai dimana sudut lereng 23,77o dengan ketinggian yang sama 12 m, sehingga diperoleh nilai (FK = 1,288).</mods:abstract><mods:classification authority="lcc">T Technology (General)</mods:classification><mods:classification authority="lcc">TN Mining engineering.
