Mine Dewatering Analysis in Pakal Island North Maluku
摘要
Nickel mining activities carried out by PT ANTAM are located on a small island with steep topography, which is the main factor that can increase erosion risk. The erosion transports some eroded road material to the mine opening area and into the mine water drainage channel. The erosion material reduces the capacity of the settling pond, so it must be redesigned. The analysis results show that the existing pool capacity is 3461.32 m3, with a water discharge of 34,6132 m3, and the ideal volume is 15341.57 m3. The redesign has a storage volume of 1,6368.131 m3 so that it can accommodate the incoming rainwater discharge.
