共著  Analyse de l’evolution des accidents de travail dans les mines de cuivre du Katanga.  John Ngoy Kalenga, Christian Tulinabo Balyahamwabo, Testuhiko Takai  Revue Congo-Afrique  CEPAS  56/ 505, 366-380  2016/05/20  1819-1010  L’article analyse de façon rétrospective les accidents industriels de la Gecamines de 1953 à 2010. Les données sur les accidents ont été recueillies au cours des visites de recherche sur terrain à la Gécamines. L'objectif de cet article est de déterminer la fréquence des accidents, leur taux de gravité, et les causes de décès. Les résultats indiquent que le taux moyen d’accidents de travail est de 48/1000 travailleurs, le taux de gravité est de 3/1000 travailleurs, et le taux d’accidents mortels de 0, 4 / 1000 travailleurs. Le transport de minerais sur les sites était la cause la plus fréquente de décès des travailleurs dans les mines de la Gécamines.

Mine safety and Industrial accidents at the Générale des Carrières et des Mines, in Katanga, Democratic Republic of Congo  Kalenga John Ngoy  Discussion Paper, Series A  Graduate School of Economics and Business Administration, Hokkaido University  277, 1-13  2014/11  URL  This paper focuses on the workplace accidents of Gecamines in a comparative perspective. Copper industry has been the cornerstone of Congolese economy since the colonial era. Katanga province is well known for its reserves of copper and cobalt. Many accidents occurred in mining operations of Gecamines. We collected data of accidents from 1957 to 2008 during the fieldwork at Gecamines. Data of this study included only the accidents that required the miner to be absent from work for at least four calendar days. This study aims to determine factors of the accidents at Gecamines in order to suggest the policy to prevent the occurrence of accidents. The results show that miners at Gecamines were more exposed to the risk of accidents than their colleagues of similar industries in Australia, Canada and the United States of America. The average frequency, severity and number fatalities per year of Gecamines were 48, 3, and 9, respectively. The reduction of accidents should be achieved by training of miners and instauration of inspectors in charge of safety.
