Abstract

Minerals which located below the surface of the groundwater require pumping activities to carry out the mining activities. The problem that has occurred so far is that the work front located lower than the portal causes the waters from groundwater seepage and underground mining equipment to be collected and pooled on the work front. This causes the work area to be flooded and causes the mining activities to be delayed up to 5 hours. The study of the mine drainage system is expected to evaluate the existing mine drainage system in the PT Bumi Suksesindo underground mine, including analysis of groundwater seepage, mine water discharge, sump volume, pump requirements and alternative pumping system networks. Based on several trial and error experiments, the groundwater inflow is 1,17 x 10-5 m3s-1 on average at each seepage’s location point. The recommendation to resolve the mine dewatering problems are an addition of a booster pump on sump 2 and sump 1, the dimensions of the sump has to be increased, add an airflow control valve to ensure that the source of air pressure is 3 bar, and a replacement of pump impeller to MT 231 coded impellers.
