Title: An analysis of productivity and cost efficiency of underground labour at George Capendel Shaft of Ashanti Goldfields Corporation (Ghana) Limited
Authors: Frimpong, Mensah
Issue Date: 3-Sep-1990
Series/Report no.: 1758;
Abstract: The treatise analyses the possibilities of increasing productivity at optimum cost. The study revealed that labour motivation at AGC is quite low. Job-centered style of supervision, machine downtime poor environmental conditions and labour unrest are among the factors hindering productivity. Productivity is analysed terms of tons or advance per man-shift. Production efficiency is the ratio of actual to the programmed productivity whereas cost efficiency is the ratio of forecast cost to the actual. The mean actual productivities of the various stopes were; for cut – and – fill (conventional) stopes (2 t/m-s), cut – and – fill (machinised) stopes (2.5 t/m-s), sublevel are 3. t/m-s, 8 t/m-s, 3.2 t/m-s respectively, and 2.5 t/m-s for shrinkage stopes. At development ends, mean productivities were 0.61 feet/man-shift for raises and 0.875 feet/man-shift for lateral development The percent-age contribution of the operating cost of mining by the various cost centers are ; stoping cost (36.56%) , slope preparation cost ( 13. 18%) -. slope development cost (26. 96%) and 2 3% for the working cost.. The study also revealed a decline in performance of AGC in terms of cost from 1980/81 to date.
