The purpose of the study was to evaluate different techniques for reducing suspended dust in mining roads. After searching for some information to fulfill this purpose this purpose we experimented with five products such as: molasses, magnesium hydroxide, TGC, sodium chloride and bischofit, some of them applied for this purpose on roads. Dust measurement data were collected and compared with previous data taken by environmental specialists and the E-Sampler dust collection device by using the assistance of the Comet software. The bischofit product revealed the best results in the areas previously treated with soil-salt; however it is not possible to apply it during the snowy season because of the insecurity it generates when the road becomes very slippery.
