Best Practices for Dust Mitigation in Mining Operations
2. Dust Collection and Filtration Systems
Dust collection and filtration systems play a crucial role in mitigating fugitive dust emissions from mining operations. These systems capture and remove dust particles from the air, preventing them from dispersing into the environment.
There are various types of dust collection systems available, each with its own advantages and disadvantages. Some of the most commonly used systems include:
- Baghouses: These are large, enclosed structures that contain filter bags made of fabric or other materials. Dust-laden air is drawn through the bags, where the dust particles are trapped and collected.
