Top 10 Questions for Continuous Mining Machine Contract Miner Interview

1. Describe the key components of a continuous mining machine and their functions.

• Shearer head: Cuts the coal from the face.
• Gathering arm: Collects the cut coal and transports it to the conveyor.
• Conveyor: Transports the coal to the surface.
• Traction system: Moves the machine along the face.
• Hydraulic system: Powers the machine’s components.
• Electrical system: Provides power and control to the machine.

2. Explain the difference between a continuous miner and a longwall miner.

Continuous miner

• Cuts and gathers coal in a continuous operation.
• Uses a rotating shearer head to cut the coal.
• Is typically used in smaller mines with thinner coal seams.

Longwall miner

• Cuts coal in a long, continuous face.
• Uses a series of rotating cutting heads to cut the coal.
• Is typically used in larger mines with thicker coal seams.

3. What are the safety precautions that must be taken when operating a continuous mining machine?

• Wear proper PPE, including a hard hat, safety glasses, and gloves.
• Inspect the machine before each use.
• Be aware of the surroundings and potential hazards.

• Troubleshoot and repair any problems with the machine.

5. How do you troubleshoot a continuous mining machine that is not cutting coal?

• Check the cutting bits.
• Check the hydraulic pressure.
• Check the electrical system.
• Check the conveyor system.
• Troubleshoot any other potential problems.

6. How do you calculate the production rate of a continuous mining machine?

• Measure the length of the face that was cut.
• Measure the height of the coal seam that was cut.
• Measure the width of the cut.
• Calculate the volume of coal that was cut.
• Multiply the volume of coal that was cut by the density of coal.

7. What are the environmental impacts of continuous mining?

• Air pollution from diesel engines.
• Water pollution from runoff.
• Land pollution from waste rock.
• Noise pollution from machinery.

8. What are the advantages of using a continuous mining machine over traditional methods of coal mining?

• Increased production rates.
• Reduced labor costs.
• Improved safety.
• Reduced environmental impact.

9. What are the disadvantages of using a continuous mining machine?

• High capital cost.
• Complex maintenance.
• Limited maneuverability.
• Potential for accidents.

10. What are the future trends in continuous mining technology?

• Automation.
• Remote control.
• Improved safety features.
• Reduced environmental impact.
• Increased production rates.
