Dust Control Solutions for Mining
Mining. Dust Control Regulations.
Dust emission regulations are essential for mining operations. They safeguard worker health, enhance community air quality, protect the environment, and ensure operational safety. Various agencies and guidelines oversee dust emissions from mining, and regulations differ by country.
In Australia, dust emissions from mining are regulated by the Australian National Environment Protection Measures (NEPM) standards for air quality, which set limits on particulate matter (PM10 and PM2.5) concentrations. The Australian Department of Climate Change, Energy, the Environment, and Water also requires mining companies to monitor and manage dust levels to maintain air quality near mining sites.
We recognise that dust control measures must go beyond meeting regulatory standards. They should also focus on minimising risks and ensuring the highest levels of safety for all involved.

Dust Control. Mining Applications.
JMS F-Series.
Fixed Dust Collectors.
Our JMS F-Series fixed-unit dust collectors offer a long-term and cost-effective solution to dust and fume control and are designed to handle high-volume dust loads. Our modular design provides flexibility in the dust control units’ size relative to the required air volumes. Our engineering team can use site and process drawings to determine airflow requirements and design ducting configuration to achieve a total dust control solution.
JMS M-Series.
Mobile Dust Collectors.
Our JMS M-Series mobile dust collectors offer air volumes from 6 m3/s (12,000 CFM) to 60 m3/s (125,000 CFM) and are available as diesel, electric, or hybrid solutions. Skid-mounted units are designed when dust collection needs are relatively static; however, track-mounted units can be used to easily move along with dust-generating processes or for temporary works.
Custom Onboard.
Dust Control Solutions.
Using our expertise in dust control, we have developed and patented a range of onboard dust control solutions for excavation equipment, including Surface Miners, large track trenchers, Skid Steers, and Posi Track Loaders. The onboard dust control solutions are effective for dealing with residual dust and debris and offer a fuel, emissions, and labour-efficient solution when space constraints prevent the use of a trail-behind dust system.
Dust Control. Mining Applications.
Underground Mining
In underground mining, dust primarily arises from the mechanical disturbance of rock and ore during activities such as drilling, blasting, crushing, and loading. These processes release fine mineral and rock particles into the air, allowing them to become airborne and circulate within the confined underground environment. Additionally, the movement of heavy machinery and transport vehicles can stir up loose particles on the mine floor, contributing to dust generation. A combination of engineering controls, proper ventilation, and dust suppression techniques is essential to manage dust in underground mining effectively.
Surface Mining / Quarrying
In surface mining and quarrying operations, dust is created through many processes, including blasting, drilling, excavating, and crushing. These activities break rock and mineral materials into fine particles that can quickly become airborne. Trucks and loaders transporting mined materials on roads and work areas can also stir dust from loose, exposed soil and rock.
Quarries near urban developments or waterways require effective dust control measures to comply with health, safety, and environmental regulations.
Managing dust in surface mining and quarrying involves implementing measures to minimise airborne particulate matter.
Mine Shutdown Works
Mine Shutdown Works are an essential part of running a mine and allow for work to be conducted safely and efficiently. These works frequently require temporary mobile dust control to mitigate the risks associated with dust generating activities. As equipment is dismantled and removed, the disturbance of previously undisturbed soil and rock surfaces releases fine particles into the air. Additionally, demolishing structures and infrastructure, such as processing plants and storage facilities, can create significant dust clouds.
Effective dust management is essential during mine shutdowns to protect workers’ health and mitigate environmental impacts on surrounding areas.
Material Processing
Dust is generated during the processing of mined materials through various stages, including crushing, grinding, screening, and separating. When ore and rock are broken into smaller particles, the mechanical action creates fine dust that can become airborne.
Processes such as crushing and milling generate high dust loads. Screening and sorting processes also generate dust by moving and agitating materials.
Handling dry materials during transfer and storage can also release dust, especially if the equipment and processes lack adequate dust control systems.
Ship Loading / Unloading
During the loading and unloading of ships that transport dry bulk materials, including iron ore, grain, and aggregates dust is generated. It is primarily caused by the handling and movement of these materials, by mechanical equipment such as grabbers, which scoop up bulk materials, conveyors that transport the materials across different points, and hoppers that hold and dispense bulk loads. Additionally, moving materials in and out of the ship’s holds can release substantial dust into the atmosphere. This dust poses potential health risks and can impact the surrounding environment, making effective dust management strategies essential during these operations.
