摘要

This research did in the North Sump area of the Air Laya Mine, PT Bukit Asam Tbk, South Sumatra. The Sump is a former open-pit mining area in the form of a vast basin. Previously this Sump functioned to gathers water from the pit. Since there is no mining operation in that pit, then that Sump functioned is changed into a disposal area, so the Sump is needed to be dried. The draining plan is carried out with mine drainage and mine dewatering. Mine drainage is an effort to prevent runoff water from enters the Sump. Mine dewatering is the effort to remove water from the Sump by pumping. The initial draining plan is not able to dry the Sump. It can saw from the water surface's elevation on the Sump that has not decreased, so it is necessary to study the plan to drain the Sump. The study conducted considers the calculation of the water balance. Water balance influenced by inflows in the form of runoff water and outflows in the form of evaporation and pumping. Based on the calculation of the water balance, three alternatives proposed in Sump drying, which from each alternative can seek changes in the volume and depth of the Sump in a certain period. The alternative I did by adding the number of pumps, the alternative II did by increasing the pump impeller rotation, and the alternative III did with the combination of alternative I and alternative II. The alternative chosen is alternative III with a drying time of 72 days.
