Abstract
The purpose of implementing a mine drainage system is to ensure that mining activity areas are not flooded during the rainy season. The mine drainage system in this study consisted of designing sump dimensions, open channels, settling ponds, and pumping and piping systems. The planned rainfall is calculated using the maximum daily rainfall from 2003 to 2022, using the Log Pearson Type III method. The result of the calculation of the planned rainfall is 194.50 m/day. The total discharge of runoff water in the study area was 17.05 m3/s, and the volume of rain was 293,976.94 m3. The sump is designed based on KEPMEN ESDM 1827 K/30/MEM/2018 so that it can accommodate a volume of incoming water of 823,392.60 m3. The pumps used to remove water from the sump to the settling pond are six Multiflo 420 EXHV RPM 1550 pumps. The pipe used is polyethylene with the type HDPE PN 16 PP 100 and requires a length of 908.42 m. The pump capacity discharge is 1,255.40 m3/s with a total head loss of 138.89 m. The channel has discharge capacity of 2.40 m3/s. The settling pond consists of three compartments designed to accommodate a volume of 61,245.20 m3 of water.
