This study has modeled occupational injuries at Gold Fields Ghana Limited (GFGL), Tarkwa Mine
using time series analysis. Data was collected from the Safety and Environment Department from January 2007
to December 2010. Testing for stationarity condition using line graph from Statistical Package for Social
Sciences (SPSS) 17.0 edition failed, hence the use of Box-Jenkins method of differencing which tested positive
after the first difference. ARIMA (1,1,1) model was then applied in modeling the stationary data and model
diagnostic was done to ensure its appropriateness. The model was further used to forecast the occurrence of
injuries at GFGL for two year period spanning from January 2011 to December 2012. The results show that
occupational injuries for GFGL are going to have a slight upward and downward movement from January 2011
to May 2011, after which there will be stability (almost zero) from June 2011 to December 2012.
Key words: Differencing, forecasting, mining, safety, stationarity, ,
