High Tech,
But Easy to Use
GRT has developed its dust suppression systems and technologies so that they are simple to use, highly efficient, and improve cost-effectiveness over time.
How the technology works
These water additive products act as dust suppressants to enhance the efficiency of water to capture the dust particles for a longer duration thereby reducing water usage and increasing dust suppression.The products or solutions can deliver these benefits using existing or readily available equipment such as existing spray systems and water lines, misting systems, water trucks, cannons, spray nozzles and overhead spray bar systems.
GRT’s dust suppression technologies fall under six main product groups:
GRT: Haul-Loc
Save water, eliminate dust, and improve safety on your haul roads.

TOTAL DUST MITIGATION STRATEGY FROM PIT TO PORT
FAQs
What is dust suppression?
Dust suppression is the corrective best practice of dealing with fugitive dust particles that have been dislodged from their source. It limits the extent to which dust particles travel in the air.
What is a dust suppression dosing unit?
A dust suppression unit is a Sustainable Mining Automated Reporting Technology (SMART) dosing unit which is a key hardware component that captures and uses powerful real-time data to improve water cart fleet management while cost-effectively eliminating dust.
How do dust suppressants work?
Different dust suppressants have different mechanisms of action. For example, surface active agents lower the surface energy of water which enables surface charge similarities with dust particles and subsequent binding of the dust particles.
Why is dust suppression important?
Dust suppression is important for water conservation through reduction of water truck movements, increased production efficiency, improved visibility during operations, reduced operator downtime, compliance to dust legislation and improved safety and health of workers and communities within the vicinity of mining operations.
How do you control dust in mines?
Dust control in mines varies with type of mine and its activities. You can control dust in mines by using liquid polymers that bind and agglomerate unbound granular materials in unsealed surfaces on haul roads and low-volume roads.
What is the biggest health risk of mining?
The biggest health risk of mining is contracting occupational lung disease. Exposure to dust at the mine often results in dust related diseases such as silicosis, coal mine workers pneumoconiosis, and lung cancer.
How does dust formation happen in mines?
Dust forms in pit to port activities. At the pit it is dislodged from activities such as blasting and drilling. On the way to the port, it is generated from hauling and material handling activities. At the port dust forms during loading and unloading activities and stockpiling.
How do miners breathe underground?
Miners breathe underground via mine ventilation systems which supply sufficient fresh air and expel contaminated air. The ventilation system dilutes and removes poisonous gases, dusts, diesel particulate matter and regulates temperature.
What our happy customers say about GRT's dust suppression solutions.
“Recognised Standard 20” for dust control in surface mines
The purpose of this recognised standard is to state ways for the site senior executive (SSE) to meet their safety and health obligations, and develop their mine’s safety and health management system (SHMS) for the control of dust (respirable and inhalable) at a surface coal mine.
