A review of dust emission dispersions in rock aggregate ...

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.

2020-6-9  Dust is an environmental issue at many quarries and crushing is the most significant source of it [1, 2].According to Sairanen and Selonen [] drilling is the most dust producing activity in natural stone quarries.Aggregate production is reported to generate mainly coarse (PM 10 or larger) particles [4, 5], whereas the majority of the dust generated during the drilling is PM 10 [].

Stone Dust in Concrete: Effect on Compressive Strength

2017-8-24  Quarry dust can be utilized in concrete mixtures as a good substitute for natural river sand giving higher strength at 50% replacement (Balamurgan et al., 2013). While using crushed stone dust as fine aggregate in concrete it is found that there is increase in compressive, flexural and tensile strength of concrete (Nagpal et al., 2013). It has ...

BEST MANAGEMENT PRACTICES PLAN FOR FUGITIVE DUST

2018-3-17  Chapter 11 of the US EPA AP‐42 document characterizes fugitive dust from stone crushing and aggregate handling as three (3) forms of particulate matter: PM, PM10 and PM2.5. PM is representative of total suspended particulate matter. PM10 and PM2.5 is the respirable fraction of particulate and can have an impact on human health.
