Abstract Fugitive dust constitutes one of the most severe environmental problems in quarries because it escapes capture. This review aims to provide overview of dust concentration caused by quarrying by synthesising the current knowledge. The 25 studies explored here were conducted in open-pit quarries or mines. Three main dust sources surfaced from the studies: drilling, crushing and hauling.

Dust control for screening systems is similar to that for crushers, although wet systems are generally not used due to blanking of the screen openings by the wet material. Screens should be totally enclosed, and water suppression systems (when compatible with the process) or dust collection and exhaust systems should be incorporated.

Quarries. Stone quarrying is a process by which rock is extracted from the ground and crushed to produce aggregate, which is then screened into desired sizes. This screened aggregate is then used for the construction of roads, rail lines, bridges, hospitals, schools, airports, factories, and homes, all of which has crucial impact on economic development of any country.
