Controlling the risk of dust exposure to workers in mines

Treat the dust on its transmission path using dust suppression techniques (e.g. water sprays, chemical additives, local exhaust ventilation (LEV), vacuum). Substitution with a lesser hazard Substitute with a less hazardous substance, such as the use of pellets rather than powders, or replace sand with garnet as abrasive blasting agent.

DUST RESULTING FROM BLASTING IN SURFACE MINES AND ITS CONTROL

Bottom initiation using Exel or Raydet systems are adopted and air decking techniques are practiced. The mining operations are very close to residential areas (villages 400 m away). Therefore, there is a strong need to control dust produced by blasting operations. Dust measurements were carried out at various distances from the point of blast.

Monitoring mine, construction and quarry dust in real-time

Jan 18, 2018· Quarries, 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.
