21
Which underground mining method uses a conveyor belt and hydraulic roof supports?
Discuss
Answer & Solution
Answer: Option B
Solution:
Longwall Mining is used in coal mining with a long face and mechanized supports.The correct answer is: Longwall MiningIt provides high recovery and automation.Mostly used for soft-rock like coal.
22
What is the primary function of a portal in mining?
Discuss
Answer & Solution
Answer: Option C
Solution:
Portal is the entrance to an adit or tunnel.The correct answer is: Surface entry to an aditIt connects the surface to underground workings in horizontal or inclined entries.It must be stable and often reinforced.
23
What is a stope in underground mining?
Discuss
Answer & Solution
Answer: Option B
Solution:
Stope is the open space left after ore is extracted.The correct answer is: A chamber where ore is minedStoping is the main ore extraction phase.It follows the ore geometry and chosen mining method.
24
Which factor is most important in selecting underground mining equipment?
Discuss
Answer & Solution
Answer: Option C
Solution:
Tunnel width and geometry determine the size and type of equipment used.The correct answer is: Tunnel width and geometryEquipment must fit safely and efficiently.Hardness affects tools, but geometry limits mobility and operation.
25
Which of the following is primarily used for ventilation in underground mines?
Discuss
Answer & Solution
Answer: Option A
Solution:
Raise can serve as a ventilation pathway.The correct answer is: RaiseIt connects lower and upper levels, allowing air circulation.Winze is vertical but driven downward; crosscut connects levels; adit is surface entry.
26
In which method is mining done under backfilled zones, allowing tight control and safety?
Discuss
Answer & Solution
Answer: Option C
Solution:
Cut and Fill involves mining a stope, then backfilling it before mining the next slice.The correct answer is: Cut and FillProvides excellent ground support and is ideal for irregular or dipping ore bodies.Minimizes dilution and risk.
27
A winze in mining refers to:
Discuss
Answer & Solution
Answer: Option C
Solution:
Winze is a vertical or inclined shaft sunk downward from an underground level.The correct answer is: Downward internal shaftIt connects lower levels and is not started from the surface like a shaft.Used for ore hoisting or ventilation.
28
Which one is a non-entry mining method?
Discuss
Answer & Solution
Answer: Option D
Solution:
In-situ leaching involves extracting minerals by dissolving them underground.The correct answer is: In-situ leachingNo physical entry is required into the ore zone.Used for soluble minerals like uranium or copper.
29
Which one of the following is used to support weak roof in underground mining?
Discuss
Answer & Solution
Answer: Option A
Solution:
Timber sets are traditional roof support structures.The correct answer is: Timber setsThey are used in weak ground to prevent collapse.Still in use for temporary or small-scale operations.
30
What is the purpose of a muck bay in a decline tunnel?
Discuss
Answer & Solution
Answer: Option B
Solution:
Muck bay is a widened section of the decline or drift.The correct answer is: Material dumping areaIt allows temporary storage of blasted rock (muck) before it is hauled.Improves traffic flow in the decline.
