RAMPEDI, M.S.P e GENC, B. An investigation into the optimization of personnel transportation to level 15 and below at Khuseleka No. 1 Shaft, Anglo Platinum. J. S. Afr. Inst. Min. Metall. [online]. 2012, vol.112, n.4, pp.323-330. ISSN 2411-9717.
The paper reports on a vacation work project conducted at Khuseleka No. 1 Shaft, Anglo Platinum, where there was a need to optimize the transport of personnel to level 15 and below. Approximately 900 men per hour need to travel between the shaft and the start of the current chairlift system. Time studies were used as the major indicator of the extent of the current problem, and it is recommended that a new chairlift system be installed to cover the distance from the vertical shaft station at level 15 to the chairlift decline station on level 15. A capital cost of approximately R10 million is necessary to carry out the proposed recommendation. Khuseleka No.1 Shaft has the capacity to wind 1070 people per hour, and the current labour complement going to the level 15 shaft station stands at 1570 employees; thus at optimum efficiency the proposed chairlift system could transport the entire shift to the start of the current chairlift system in only 1 hour and 45 minutes. Reducing the distance walked at the start of the shift may also have an impact on productivity.
