workers or other vehicles claim an average of five lives 2Og5e  
each year in surface and underground metal/nonmetal mining /F"eqMN  
operations. Many more workers are severely injured. Although u$zRm(!RB  
technologies exist that could prevent these collisions, (radar, B6TE9IoSb8

and are not being used widely. New developments in radio-frequency F:#5Edo}A
