L'nivrr~lfi.. of Pretoria, L';outh Africa Abstract Excessivc dust generation from unpaved mine haul roads is a problem common to most surface mining operations and especially so in scmi-arid and arid areas. Optunal wearing course material selection parameters reduce, but do not totally eliminate the potential to produce dust. Mincs rarely have optimally designcd and maintained roads: and the problem of identifying the haul road dust dcfccl, quantifying its impact on health-risk and assigning remediation priorities within thc constraints of limited capital and inanpower is problematic. This paper describes fugi~ive dust emission and operator-exposure characteristics associated with mine haul trucks running on unpavcd mine haul roads in Sub-Saharan Africa. Following a description of fugitive dust emi
