Abstract—Collisions between haulage equipment and pedestrian ~_v?M%5i  
workers or other vehicles claim an average of five lives J9J[.6k8  
each year in surface and underground metal/nonmetal mining ncS.~F
 
operations. Many more workers are severely injured. Although 
$!P(Q  
technologies exist that could prevent these collisions, (radar, 1(6B|w5+  
closed-circuit TV, and backup alarms), they do have limitations b6%T[B B  
and are not being used widely. New developments in radio-frequency VP^Yph 8R  
identification (RFID) systems show promise for reducing nHxos`Qx  
the number of collisions. This paper, originally presented in 1998, _[}r2,e  
describes tests conducted on off-the-shelf RFID systems and the FtbqZN[  
subsequent development of a custom RFID system that could be csZIBi  
used for both surface and underground m .. EacqQFErl
