Grydale Mobile Dust Control Solutions – Helping Tunnel Builders Meet Tougher Workplace Exposure Limits (WELs)
Dust control in tunnelling extends beyond compliance, it’s about protecting workers and keeping projects on schedule. Grydale® mobile dust collectors have proven effective on projects globally, making tunnel construction safer, cleaner, and more efficient.
Unique Challenges
Each tunnelling project brings its own unique challenges, including confined spaces, limited ventilation, and varying geological conditions. Effective dust control solutions is therefore crucial for worker safety and project efficiency.
During excavation, shotcreting, and haulage, airborne dust can quickly build up, affecting visibility and raising the risk of respiratory diseases such as silicosis. Traditional dust suppression systems often fail to address these challenges, which is why contractors are increasingly adopting the use of mobile dust collection solutions. These solutions not only enhance main ventilation but also provide effective dust extraction at the source.
Localised Extraction for Confined Spaces
Grydale® mobile dust collectors are designed to operate in line with excavation, delivering powerful airflow and filtration that captures dust directly at the source. With air volumes up to 60m³/s, these units are designed for continuous, high-volume dust generation.
Minimising DPM and Supporting Sustainability
Electric and hybrid models help to reduce the levels of diesel particulate matter (DPM) in confined environments, improving air quality for workers and further reducing the strain on ventilation systems. By eliminating or minimising diesel exhaust emissions at the source, these machines create a safer and healthier workspace underground. At the same time, they align with the mining industry’s broader push toward decarbonisation and sustainability, supporting operators in meeting environmental and ESG performance targets.
Safety and Compliance
As Workplace Exposure Standards (WES) tighten and transition to Workplace Exposure Limits (WELs), especially around silica dust, tunnel constructors must demonstrate effective control measures.
A Proven Solution in the Field
Grydale units have been deployed in tunnelling projects across Australia, UK, Saudi Arabia and Canada, where reliability, mobility, and ease of maintenance have been essential. The ability to track, step, tow, and relocate units easily means one solution can service multiple headings, maximising equipment utilisation, reducing costs to the project and improving project operational efficiency.
