Coal Fire Suppressant
Coal Dust Suppressant is a material or chemical mixture used to control coal dust from spreading into the air during the process of mining, transporting, storing, or processing coal.
Here is the full explanation:
Definition
Coal Dust Suppressant functions to suppress fine particles of coal dust so that they remain attached to the surface of the material or soil, so that they do not fly away due to wind, vibration, or mechanical activity (for example from trucks or conveyor belts).
Main Objective
-
Reduce air pollution due to coal dust (PM10 and PM2.5).
-
Improve occupational safety as exposure to excess coal dust can cause respiratory distress.
-
Meet environmental standards set by government or regulatory agencies.
-
Reduce material loss due to dust flying from coal piles.
Types of Coal Dust Suppressant
-
Water-based - often used because it is cheap and easy to apply, but the effect is temporary.
-
Chemical-based - contains polymers, surfactants, or resins that form a thin film over the coal surface, lasting longer.
-
Oil-based or bitumen emulsion - forms a very effective protective coating, but is more expensive and may cause residue.
Method of Application
-
Direct spraying on mine roads, coal piles, or conveyors.
-
Mixing or blending with coal during the loading process.
-
Automated systems such as sprinklers or nozzles in specific areas.
Product Examples
Some examples of dust suppressant products commonly used in the mining industry include:
-
DC-22, Envirotac II, Dust-A-Side, Soilworks Durasoil, or local products with polymer or lignosulfonate active ingredients.
