Track: Case Studies

Abstract

This case study delves into optimizing dewatering processes at the Karowe Diamond Mine by reconfiguring pipeline routing, with a specific focus on leveraging centrifugal pumps to alleviate frictional head loss. Through meticulous analysis, a novel pipeline route was proposed, significantly shortening the distance from the pit sump to the discharge dam. The original span of 2444.215 meters was successfully reduced to 1831.886 meters, representing a substantial improvement in operational layout. By strategically utilizing centrifugal pumps, the proposed route demonstrated enhanced performance, increasing the total discharge from the existing 120m³/h to 168m³/h. These results underscore the significant advantages of the new pipeline route in terms of efficiency, capacity, and cost-effectiveness. Additionally, the study suggests incorporating stage tanks between the two centrifugal series-connected pumps to prolong the lifespan of mechanical seals. Overall, this research provides a valuable blueprint for mining operations seeking to streamline dewatering processes, leading to notable performance enhancements and cost savings. Moreover, it's essential to highlight the financial aspect: the total cost of the current pipeline stands at P3,825,115.00, whereas the proposed pipeline's total cost amounts to P2,728,495.00. Consequently, the proposed pipeline achieves a total cost reduction of P1,096,620.00, further emphasizing its economic feasibility and benefits.
