To clarify the characteristics of pumpage and drainage in mined areas, underground mining data, drainage data, and weather data in a coal mine were collected.The pumpage rate is divided into two parts, the first is pumped under the seafloor and the second is pumped under the land. At the land, the pumpage rate has a correlation with annual precipitation. However, the pumpage rate from seafloor has no relationship with annual precipitation, cumulative mined area, or annual mined area.The sources of drainage are classified based on main drifts, faults, and mined coal seams. Bar graphs for the variation of drainages from the sources show the movement of drainage peaks with development of new mined areas.Numerical analyses about mine drainage are carried out to estimate and to make modeling the hydrogeological conditions. The records of drainage and the results of numerical analyses reveal the hydrogeological characteristics around mined areas. From the variation of drainages, the feature of drainage was simply modeled. These models are useful to predict the drainage in a new developed mining area.
