Abstract
The effectiveness of modern mining depends on proper mine designs and implementation of mining standards. Proper mine designs and implementation of mining standards help in maximizing ore recovery and reducing dilution. Reconciliation statistical studies of 2014 and 2015 indicate that there has been ineffective stope designs and improper implementation of stoping standards which has led to reduced stope recovery and increased dilution at Mufulira mine. Therefore, this study was aimed at determining the causes of low stop recovery and dilution. The actual average monthly stop recoveries where reviewed and compared with the targets of 80% and 84 % Mechanised Continous Retreat one (MCR1) and Mechanised Continous Retreat two (MCR1). The Actual Monthly dilutions were reviewed and compared with the theoretical values of 31% and 30 % for MCR 1 and MCR 2 respectively.
The study carried out has established some of the causes of low stop recovery and increased dilution are attributed to lack of proper implementation of preset mining standards. Hence based on these finding appropriate mine designs and practices have been recommended.
