Engineering control of dust at the quarry can involve the substitution of hand held hammers with modern crushers that are enclosed. The use of such a crusher is a far-fetched dream for most artisanal and small scale miners in Misisi compound due to the high cost of crushers. The type of dust control that can easily be applied is management control.Web

replacement of sand with quarry dust in the 50% - 50% (Mix 3) ratio was the most effective and showed an increase in compressive strength. It was also concluded that the compressive strength of concrete, with 50% Sand and 50% quarry dust (Mix 3), under thermo shock and high temperature showed the least reduction in strength.Web

The amount of dust produced during blasting is estimated to be as high as 20%. Mitchell (2007) suggested that the quarrying sector would consider using new technologies, which would reduce the fine production. Hence, further research work is required to identify the capital and operational costs associated with quarry dust.Web

A 10 tonne pile of sand is now going for between Sh20,000 and Sh25,000 from about Sh15,000 a few weeks ago. This has forced some property developers to suspend their projects indefinitely, while others have turned to quarry dust – a by-product of the crushing process – which costs Sh10,000 per 20 tonnes.Web
