aggregates via crushing and sieving [10]. By drilling and blasting, the rock material is detached from the bedrock to fit in a crusher feeding bin. Larger rocks are fragmented with a hydraulic impact hammer before crushing. In aggregate quarries, the most dust-generating process is crushing and sieving. The drilling and blasting also causes dust

This study compares modelling results to measured concentrations near dust sources in a natural stone quarry and in two aggregate quarries. In the natural stone quarry, the dust source was drilling and in the aggregate quarries, it was crushing.

The intimate mix of foam and breaking aggregate within each crusher is often adequate to control dust throughout the entire production process. The foam is produced at source by the controlled introduction of water and compressed air.

Three main dust sources surfaced from the studies: drilling, crushing and hauling. Analysis revealed a range of dust concentrations caused by different quarrying operations. Crushing was the most significant dust source, while drilling caused the highest variation.

Dust from quarries tends to be unavoidable, particularly when the weather is very dry. Activities, including the drilling, blasting, loading, hauling, conveying and crushing and screening of rocks all generate dust as does transporting the finished products.

Crushed – rock aggregates are produced in quarries. In areas where natural sand and gravel aggregate deposits are insufficient to handle local demand, larger quarry rocks are processed in an impact crusher to create crushed-rock aggregate.

In the Lambayeque region, non-metallic mining activities produce dust containing silica, posing risks to workers. Data suggests around 177,692 workers in Peru could be vulnerable to this contaminant. At a construction aggregate crushing plant in Lambayeque, operations proceed without sufficient dust suppression and control
