GRT: Longwall is used to super-activate water sprayed to control coal dust in longwall and continuous miner operations.
Coal is by nature hydrophobic (water hating) and at the microscopic level repels water – so despite the volumes used, the finest particles simply bounce off of sprayed water.
These fine particles, which may not even be visible, are the most hazardous to health, leading to diseases such as black lung and other respiratory ailments.
GRT: Longwall super-activates water to overcome this behaviour causing the water to immediately coat airborne particles, forcing them to drop out of suspension in the air.
Injected into existing spray systems, GRT: Longwall saturates the coal face and intercepts fine particles immobilising fugitive dust. Importantly, the solution does not alter the burning properties coal or quality of your products, by targeting and mitigating only dust.
Dust Suppression at the Coal Face
Whilst developed specifically for the coal face, GRT: Longwall can also be applied to manage dust from conveyors, large mineral stockpiles or any fine or pulverised minerals in transit.
GRT will work with you to devise a site-specific dust mitigation strategy to meet the challenges facing your project. We can also provide ongoing dust monitoring services to ensure the most cost effective protection over the life of your project.
The key areas of use for GRT: Longwall include:
- Safety Management: Workers are protected from harmful effects from wind-borne particles such as black lung.
- Efficiency – Improve efficiency of existing spray systems.
- Adaptable – also applicable for dust on conveyor systems and in transit
- Environmental Management – Mitigate the impact of dust on surrounding environment and on people.
Compared to conventional processes, GRT: Longwall offers:
- Easy application through existing or bespoke systems
- Health Benefits: Strips out hazardous dust particles – eliminating the cause of respiratory illness such as black lung
- Robust product characteristics allow it to be applied across a diverse range of industries
- Cost benefits from improving the efficiency of longwall and continuous miner operations
- Environmental benefits as less water is wasted trying to manage dust
Polymer Modified Cement
Polymer modified cement created by Global Road Technology is a combination of cementitious binder, GRT polymer, water and granular material. These components are mixed together and compacted in the early stages of the hydration process to form a pavement layer that is subsequently cured.
Effective soil binder & erosion control
GRT-ENVIRO SOIL BINDER & EROSION CONTROL is an organic soil conditioner based on a water-soluble polymer. This product can be added to irrigation water to reduce soil erosion by agglomerating fine particles that otherwise would be carried away by surface water runoff.
Counter Terrorism Landmine Clearance Technology
An expeditionary product with unique morphology, GRT1000 aids in the detection of sub-surface threats, such as landmines. Invisible to the naked eye, this patented state-of-the-art solution warns armed forces when roads and tracks have been disturbed.
Aerial Deployed Dust Control
An aerial deployed, military grade dust control solution, GRT2000 establishes dust free temporary landing zones in the operational theatre within minutes. Not relying on ground based combat engineers, it can be delivered almost anywhere, mitigating brownouts and improving safety.
Self Healing Runways
A novel biomimetic formulation, GRT3000 is designed to facilitate rapid construction of tactical and emergency self-healing runways in the operational theatre. Providing substantial increases in compression as well as tensile strength, GRT3000 runways are ultrathin and failure resilience.
(Black) Dust Control Polymer Sealant
Engineered to combat the problems of fugitive dust and soil stabilization on unpaved roads, GRT8000 compounds with each application to bind dust particles together. Preventing dust from becoming airborne, overtime applications can be reduced and eventually stopped.
(Black) Polymer Soil Stabilization
GRT’s most advanced polymer soil stabilization product, GRT9000 is engineered for use in the construction of high-quality and cost-effective pavements. Mitigating surface degradation, GRT9000 bonds soil or pavement particles together, improving compressive strengths, high tensile resilience and water impermeability.
