Research from coal fields show that increased production from coal mines resulted in a wider pit. Changes in the water catchment area resulted in changes in the calculation of mine water volume. Excessive mine water volume affects mining activities. Large amounts of water in the pit causes disruption in excavation and loading and hauling activities. Therefore, the design of mine drainage systems is required. The purpose of the study is to analyse statistically the parameters of the mine drainage system, and to design the mine drainage system; including open drain, sump, and settling pond. The research tools used include the calculation of runoff water discharge that requires statistical analysis for rainfall data processing and the determination of catchment area (CA). The open channel dimension and settling pond design is based on the sump volume calculation. The research area has high rainfall clased for the particle to settle is 30.38 minutes. The percsification, solid percent 2.66 % with settling rate 0.0027 m/s; the time requirentage of theoretically suctioned particle is 83 %, and the settling pond maintenance time that has 4 compartments is 15, 16, 19, and 23 days.
