Abstract
This report presents the results of an investigation on the safety of the impactor shaft-sinking system in comparison with conventional shaft-sinking technology. A detailed study of the impactor system was performed to identify and recommend design changes for optimum safety conditions. A comparison of the impactor machine and its support systems with conventional shaft sinking was made on the basis of relative risk levels. Risk incorporates measures of both the frequency and the potential consequence of accidents. An evaluation of the component operations of the impactor shaft-sinking system was performed using a failure modes and effects analysis (fmea) methodology. The results of this analysis show generally that the impactor shaft-sinking system is safer than conventional shaft sinking. The potential risk of conventional shaft-sinking operations could be reduced by an average of over 35 percent with use of the impactor shaft-sinking system.
