Abstract
Research from coal fields show that increased produ
ction from coal mines resulted in a
wider pit. Changes in the water catchment area resul
ted 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 hau
ling activities. Therefore, the design of mine
drainage systems is required. The purpose of the st
udy is to analyse statistically the parameters of
the mine drainage system, and to design the mine dr
ainage 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 a
nd 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 classification, sol
id percent 2.66 % with settling rate 0.0027 m/s; th
e
time required for the particle to settle is 30.38 m
inutes. The percentage of theoretically suctioned
particle is 83 %, and the settling pond maintenance
time that has 4 compartments is 15, 16, 19, and
23 days.
