Conceptual of Mine Sequence (X-Section)

Tingkatan warna menggambarkan Plan Sequence Bulanan

Tahapan penambangan (sequence) dimulai dari no. 1, 2, 3, dst dengan metoda bench level per 12 m

Setiap no sequence mempunyai nama shell, dengan pola penamaan sebagai berikut PN1HW036B120S09

Dimensi Shell 100 x 200 x 12 m, tergantung kemampuan unit (digging, grade, loading area




Conceptual of Mine Sequence (Long Section)

Arah sequence dimulai dari sidewall menuju ke endwall, kemudian secara bertahap sisi endwall akan didalamkan lebih dulu agar seluruh darinase dapat diarahkan ke posisi sump. Konsep pemotongan dan pola sequence dilakukan dengan mempertimbangkan ramp design overall grade 8%, pada setiap jarak 200 m baru dilakukan penekanan level sedalam 12 m.

Overall grade 8% Sump Area
