Maintaining production levels in underground mining operations during pandemics - a case study

Abstract

The outbreak of pandemics has dire consequences on businesses, industries and economies. The resulting ill-health and natural panic of the workforce tend to impact production levels, yet serious businesses such as mining ventures, must strive to make profit. To achieve objectives, businesses must put in measures to remain afloat. In this study, measures implemented by Chirano Gold Mines Limited (CGML) during Covid-19 were examined. Secondary production data spanning from 2019 to 2021 was used to appraise the performance of the mine in maintaining production levels in underground operations during the surge of the pandemic by using field visits and the administration of questionnaires. The data analysis showed that in 2020, 98.23 % and 72.72 % of the target for production and development, respectively, were met; also, 72.95 % and 92.61 % of the blasting target and ore tonnes mined were achieved respectively. Among the three years, 2020 had the highest ore production tonnage, with June recording the least value and October recording the highest value. The study found that education, effective communication of Covid-19 protocols, and the use of working shift manoeuvres were key in achieving the targets.
