Essential Questions and Answers on Double Ended Ranging Drum Shearer in "MISCELLANEOUS»UNFILED"
What is a Double Ended Ranging Drum Shearer (DERDS)?
A Double Ended Ranging Drum Shearer (DERDS) is a specialized mining machine used for continuous surface mining of coal and other soft minerals. It consists of a large, rotating drum equipped with cutting teeth at both ends, allowing it to operate in both directions. The DERDS is designed to shear the mineral from the seam at the bottom of a coal pit or quarry.
How does a DERDS work?
The DERDS operates on a principle called ranging. The rotating drum is mounted on a frame that can move laterally along the face of the mineral seam. As the drum rotates, the cutting teeth engage with the mineral, shearing it into smaller pieces. The cut material is discharged onto a conveyor belt that transports it to the surface.
What are the advantages of using a DERDS?
DERDS systems offer several advantages over traditional mining methods:
- High efficiency: The ranging mechanism allows the DERDS to operate continuously, resulting in high production rates.
- Flexibility: The ability to move laterally enables the DERDS to follow the undulations of the mineral seam, reducing waste and increasing yield.
- Safety: The enclosed design and automated operation of the DERDS minimize the risk of injuries or accidents.
- Cost-effectiveness: The high efficiency and low operating costs of the DERDS make it an economical mining solution.
In what types of mining operations are DERDS typically used?
DERDS are primarily used in surface mining operations, including:
- Coal mining: DERDS are widely employed in open-pit coal mines to extract coal from shallow seams.
- Lignite mining: DERDS are used to extract lignite, a type of low-rank coal, from surface deposits.
- Oil sands mining: DERDS are used to extract oil sands from surface mines, where the bitumen is separated from the sand.
- Potash mining: DERDS are used to extract potash, a potassium-rich mineral, from surface deposits.
Final Words: DERDS is a specialized piece of mining equipment used to extract coal efficiently. It is a valuable tool in the mining industry, helping to increase productivity and reduce costs.
