Question

In a fully mechanized bord and pillar mining system, winning of coal and its transportation from the face is commonly carried out with the combination of

• A. Continuous miner, shuttle car, feeder breaker and belt conveyor
• B. Continuous miner, LHD, feeder breaker and chain conveyor
• C. Continuous miner, SDL, feeder breaker and belt conveyor
• D. Continuous miner, shuttle car, feeder breaker and chain conveyor

Hint:

The combination of continuous miner, shuttle car, feeder breaker, and belt conveyor is a standard setup in mechanized bord and pillar mining for efficient coal extraction and transport.

Answer 1

The Correct Option is A

In a fully mechanized bord and pillar mining system, the process of winning coal and transporting it from the face typically involves a continuous miner to cut the coal, a shuttle car to transport the coal from the miner to a feeder breaker, which crushes the coal into smaller sizes, and finally a belt conveyor to move the coal out of the mine. This combination ensures efficient and continuous operation. LHD (Load-Haul-Dump) and SDL (Side Discharge Loader) are more suited for different mining methods, and chain conveyors are less commonly used in this setup compared to belt conveyors.
Thus, the correct answer is Continuous miner, shuttle car, feeder breaker and belt conveyor.
