All quarries include hauling of raw material and products. According to Reed [14], hauling produces significant amounts of dust (even 80-90%) in open-pit quarries. Kissell [12] reported that haul road dust is mainly formed during other processes in the quarry (e.g. crushing) and the hauling re-entrains the dust in the air. Hauling causes air
