Underground gold mine of PT. Aneka Tambang tbk. UBPE Pongkor is located in mountaineous area, the underground opening are relatively closed to the surface so the effect of ground water and surface water become an important concern to the mining activities. Mining operation applies cut and fill stoping method. The mineout spaces in the stope are back filled with slurry (60percent solid) from processing plants reject through piping system. Main access to reach mining area is using horizontal tunnel (adit) which called mine haulage level 500. The advance of mine operation applies the overhand method start from level 500, so that mine water and ground water will flow down and accumulated to MHL 500. |
