Dust Control Methods
Controlling Dust Emissions Dust emissions can be prevented or reduced in four basic ways: 1. Limit the creation or presence of dust-sized particles. 2. Reduce wind speed at ground level. 3. Bind dust particles together. 4. Capture and remove dust from its sources. Some dust control techniques work with many sources of dust:

The fugitive dust control plan (Plan) at the Sheridan Quarry Plant consists of dust mitigation measures to control fugitive dust emission generated by activities at the facility and their potential impacts on the environment and the surrounding community. This plan does not address particulate or gaseous emissions from a kiln, clinker cooler

Controlling the risk of dust exposure to workers in mines
Sep 21, 2018Sep 21, 2018The risk of workers being exposed to hazardous dust particles should be controlled using the hierarchy of controls shown below. Controls should focus on higher-order controls (e.g. elimination, substitution and isolation of the hazard) as the most effective means of treating the hazard.

Monitoring mine, construction and quarry dust in real
Jul 02, 2015Jul 02, 2015Quarries, rock crushing operations, major earthworks and open cast mines are by nature a dusty business. Unearthing and moving thousands of tonnes of soil and aggregate each day results in high levels of dust on-site and at the boundary. For sites bordering populated areas, fugitive dust emissions can become a source of tension between site managers and the community.

The consequences of inadequate dust control and the options available. Uncontrolled dust and erosion can cause a multitude of problems for quarry operators. For example, the build-up of dust on site machinery can cause frequent and expensive breakdowns, while dust that exits the site boundary through wind effect or on vehicles can be a nuisance
