In-Stope Atomisation for Dust Suppression

Controlling respirable dust in underground mining is critical to improving air quality and reducing occupational health risks. One of the most effective dust control methods is preventing dust from becoming airborne and removing dust from ventilating air. Among the proven technologies, water-based dust suppression, especially In-Stope Atomisation, has shown significant results in reducing airborne particulate matter.

Water atomisation transforms bulk liquid into fine droplets or mist using increased air pressure. These smaller droplets, travelling at higher velocities, effectively capture dust particles during operations. In-Stope Atomisation applies this principle by deploying fine water sprays in stopes and development ends, reducing dust liberated during scraping and improving the overall ventilating air quality.

Key benefits

  • Prevention of respirable dust becoming airborne
  • Improved dust capture from ventilation air
  • Enhanced occupational health outcomes
  • Up to 79.2% reduction in Respirable Quartz Concentration (RQC) at source

This technology is widely adopted across South African underground mines and shows potential for broader applications in high-dust areas, including:

  • Belt transfer points
  • Crushers
  • Tipping areas
  • Spray curtains in haulages

In-Stope Atomisation supports the mining industry’s Zero Harm goals by offering a reliable, efficient and scalable solution for dust suppression.
