Analysis of Electrical Accident Prevention Countermeasures

摘要

The report provides a detailed analysis of 23 electrical accident countermeasures contemplated for use in the metal-nonmetal mining industry. The costs and potential benefits of implementing groups of countermeasures are estimated and methods are outlined by which countermeasures can be selected in an effective manner. The analysis is based largely on an extensive electrical accident event tree which is developed in detail. For those countermeasures that are not currently technically feasible, several prototype devices were developed to help speed development. These included a trolley arc eliminator and a safer mine electricians' multimeter.
