81
Which opening is primarily designed for haulage in underground metal mines?
Discuss
Answer & Solution
Answer: Option B
Solution:
Drift is a horizontal tunnel following the vein or used for transport.The correct answer is: DriftIt connects levels, loading points, and ore passes.Vent raises serve airflow; winzes are vertical.
82
What is the term for a horizontal underground opening made at the lowest level to drain water?
Discuss
Answer & Solution
Answer: Option D
Solution:
Drainage adit is a horizontal tunnel designed to remove water via gravity.The correct answer is: Drainage aditEspecially common in older mines to reduce pumping needs.Positioned below the lowest active level.
83
Which of these stoping methods involves leaving horizontal pillars to support the roof?
Discuss
Answer & Solution
Answer: Option B
Solution:
Room and pillar leaves ore pillars behind to support the roof.The correct answer is: Room and pillarUsed for flat-lying deposits like coal and potash.Room extraction can be partial or full.
84
What is the key benefit of sublevel stoping?
Discuss
Answer & Solution
Answer: Option C
Solution:
Sublevel stoping uses multiple drilling levels and longhole blasting.The correct answer is: Fast production ratesSuitable for steep, competent ore bodies.Efficient but less selective and has moderate dilution.
85
What is a typical application of raise boring?
Discuss
Answer & Solution
Answer: Option C
Solution:
Raise boring drills a small pilot hole, then enlarges it to full diameter.The correct answer is: Creating smooth vertical holesUsed for ventilation shafts, ore passes, and service holes.Safer and faster than conventional raises.
86
Which method involves ore fragmentation mainly by gravity?
Discuss
Answer & Solution
Answer: Option C
Solution:
Block caving undermines a large ore block, causing it to collapse under its own weight.The correct answer is: Block cavingMinimal drilling and blasting once caving begins.Low cost per ton but high dilution.
87
Which underground transport equipment operates best on steep gradients?
Discuss
Answer & Solution
Answer: Option C
Solution:
LHDs are versatile and maneuverable, ideal for steep or winding drives.The correct answer is: LHDs (Load-Haul-Dump)They are diesel or electric powered and work efficiently in ramps.Rail and belts are limited on gradients.
88
What is the purpose of pre-splitting in underground development?
Discuss
Answer & Solution
Answer: Option C
Solution:
Pre-splitting involves drilling closely spaced holes along the boundary of excavation.The correct answer is: Controlled wall breakageIt reduces overbreak and maintains stable tunnel walls.Used before main blasting.
89
What does "face advance" refer to in tunneling?
Discuss
Answer & Solution
Answer: Option C
Solution:
Face advance is the measure of how far the tunnel is extended after each blast or round.The correct answer is: Distance the tunnel front progressesIt's an indicator of development rate and efficiency.Typically measured in meters/day.
90
In development headings, what is typically installed immediately after blasting and scaling?
Discuss
Answer & Solution
Answer: Option C
Solution:
Ground support system like rock bolts or mesh is applied right after cleaning.The correct answer is: Ground support systemThis ensures worker safety and tunnel stability.Other installations follow once safety is ensured.
