11
In cut and fill mining, what is typically used for backfilling?
Discuss
Answer & Solution
Answer: Option B
Solution:
Backfill supports the stope roof and walls.The correct answer is: Cemented tailingsProvides structural strength and allows safe mining above.Also reduces surface tailings.
12
Which heading direction is usually driven along the ore body?
Discuss
Answer & Solution
Answer: Option D
Solution:
Drift is a horizontal tunnel driven along the vein.The correct answer is: DriftUsed for exploration, ore access, and transportation.Crosscuts go across strata to reach ore.
13
What is the term for a vertical opening between levels used for ore movement?
Discuss
Answer & Solution
Answer: Option D
Solution:
Ore pass is a vertical or inclined opening for gravity ore transfer.The correct answer is: Ore passCommonly used with chutes or grizzlies.Reduces hauling distance and energy cost.
14
Which stoping method uses drilling and blasting from sublevels?
Discuss
Answer & Solution
Answer: Option B
Solution:
Sublevel stoping uses longhole drilling between sublevels.The correct answer is: Sublevel stopingOre is blasted and collected below.Works well in competent rock.
15
Which of the following increases the risk of rockbursts?
Discuss
Answer & Solution
Answer: Option C
Solution:
Rockbursts are violent rock failures due to stress release.The correct answer is: High in-situ stressOccurs at deep levels where stress builds up.May cause sudden collapse or ejection of rock.
16
What is the main function of a hoist in a vertical shaft?
Discuss
Answer & Solution
Answer: Option D
Solution:
Hoists are winches that move skips, cages, and loads in shafts.The correct answer is: Material and ore liftingEssential for vertical transport in deep mines.Drum or friction hoists are commonly used.
17
What is typically installed in raises to allow safe climbing?
Discuss
Answer & Solution
Answer: Option C
Solution:
Raise ladders with platforms every few meters ensure safe access.The correct answer is: Ladderway with landingsRequired by safety regulations for emergency egress.Chains are unsafe; conveyors are for ore.
18
Which mining method is most compatible with automation and remote operation?
Discuss
Answer & Solution
Answer: Option A
Solution:
Longwall mining uses mechanized shearers and self-advancing supports.The correct answer is: Longwall miningHighly automated, especially in coal mining.Controlled from surface or control rooms.
19
What is the purpose of scaling in underground mining?
Discuss
Answer & Solution
Answer: Option C
Solution:
Scaling is done after blasting to remove loose rock from walls/roof.The correct answer is: Removing loose rockPrevents rock falls and improves safety.Performed manually or with mechanized scalers.
20
What determines the choice between shaft and ramp access?
Discuss
Answer & Solution
Answer: Option C
Solution:
Access design depends on operational economics.The correct answer is: Depth and production rateShafts are better for deep, high-production mines.Ramps are economical for shallow or selective mining.
