Top 10 Questions for Coal Handler Interview

1. What are the different types of coal and their properties?

• Bituminous coal: This is the most common type of coal and is characterized by its high energy content and low moisture content.
• Anthracite coal: This is a hard, black coal with a high carbon content and a low moisture content.
• Lignite coal: This is a soft, brown coal with a high moisture content and a low energy content.
• Sub-bituminous coal: This is a coal that falls between bituminous and lignite coal in terms of its properties.

2. What are the different methods used to extract coal?

Surface mining

• Strip mining: This involves removing the overburden (soil and rock) overlying the coal seam and then extracting the coal.
• Open-pit mining: This involves digging a large pit in the ground and then extracting the coal.

Underground mining

• Room-and-pillar mining: This involves creating a network of rooms and pillars in the coal seam and then extracting the coal from the rooms.
• Longwall mining: This involves creating a long, narrow tunnel in the coal seam and then extracting the coal from the tunnel.

3. What are the different types of coal handling equipment?

• Conveyors: These are used to transport coal from one location to another.
• Loaders: These are used to load coal onto conveyors or into trucks or rail cars.
• Crushers: These are used to break down large pieces of coal into smaller pieces.
• Stackers: These are used to stack coal into piles.
• Reclaimers: These are used to remove coal from piles.

4. What are the safety precautions that must be taken when handling coal?

• Wear appropriate personal protective equipment (PPE), such as a hard hat, safety glasses, gloves, and a dust mask.
• Be aware of the potential for coal dust explosions and take steps to prevent them, such as using water sprays and keeping the area clean.
• Be aware of the potential for coal fires and take steps to prevent them, such as keeping the area free of debris and using fire extinguishers.
• Be aware of the potential for slips, trips, and falls and take steps to prevent them, such as keeping the area clean and free of obstacles.

5. What are the environmental regulations that must be followed when handling coal?

• The Clean Air Act: This act regulates air pollution, including emissions from coal-fired power plants.
• The Clean Water Act: This act regulates water pollution, including discharges from coal mines.
• The Resource Conservation and Recovery Act: This act regulates the disposal of solid waste, including coal ash.

6. What are the key quality parameters of coal and how are they measured?

• Moisture content: This is measured by drying a sample of coal and then weighing the remaining dry coal.
• Ash content: This is measured by burning a sample of coal and then weighing the remaining ash.
• Sulfur content: This is measured by analyzing a sample of coal for sulfur.
• Heating value: This is measured by burning a sample of coal and measuring the amount of heat produced.

7. What are the different types of coal blending and why is it done?

• Homogenization blending: This is done to create a coal with a consistent quality.
• Quality blending: This is done to create a coal with a specific quality, such as a high heating value or a low sulfur content.
• Cost blending: This is done to create a coal that is cost-effective.

8. What are the different types of coal storage and why is it important?

• Stockpiles: These are used to store large amounts of coal.
• Silos: These are used to store smaller amounts of coal.
• Hoppers: These are used to store coal that is being fed into a process.
• It is important to store coal properly to prevent it from losing its quality and to prevent the release of coal dust.

9. What are the different types of coal transportation and why is it important?

• Trucks: These are used to transport coal over short distances.
• Rail cars: These are used to transport coal over long distances.
• Conveyors: These are used to transport coal within a plant or facility.
• It is important to transport coal safely and efficiently to prevent spills and accidents.

10. What are the different types of coal utilization and why is it important?

• Power generation: Coal is used to generate electricity in power plants.
• Industrial use: Coal is used to power industrial boilers and furnaces.
• Residential use: Coal is used to heat homes and businesses.
• It is important to use coal efficiently to minimize waste and pollution.
