Each section contains 100 MCQs on Mine Development and Mining Methods .
61
Which of the following is the main advantage of using a decline ramp over a vertical shaft?
Discuss
Answer & Solution
Answer: Option D
Solution:
Decline ramps allow trucks and equipment to access the ore body without hoisting.The correct answer is: Continuous vehicular accessThis is ideal for shallow to medium-depth deposits.Shafts are more efficient for very deep mining.
62
What is the purpose of using shotcrete in underground mines?
Discuss
Answer & Solution
Answer: Option B
Solution:
Shotcrete is sprayed concrete used to support exposed rock surfaces.The correct answer is: Ground supportIt prevents rock falls and stabilizes tunnel walls and ceilings.Often combined with mesh and bolts.
63
Which of the following mining methods is best suited for steeply dipping, narrow ore bodies?
Discuss
Answer & Solution
Answer: Option C
Solution:
Shrinkage Stoping is ideal for steep and narrow ore zones.The correct answer is: Shrinkage StopingBroken ore is stored in the stope to support walls and later extracted.Longwall is used in flat seams, especially coal.
64
What does an ore pass do in underground mining?
Discuss
Answer & Solution
Answer: Option B
Solution:
Ore pass is a vertical or inclined passage used to move ore downward.The correct answer is: Transports ore to lower levels by gravityIt increases efficiency by reducing hauling distance.Proper design prevents blockages and wear.
65
What is the main hazard during raise development?
Discuss
Answer & Solution
Answer: Option C
Solution:
Raise development involves upward excavation, which exposes workers to falling debris.The correct answer is: Falling rocks and materialProper scaling and support are essential to minimize risks.Raise climbers or raise boring machines reduce manual exposure.
66
What does "rill stoping" combine in its mining approach?
Discuss
Answer & Solution
Answer: Option C
Solution:
Rill stoping uses elements of sublevel and shrinkage stoping.The correct answer is: Shrinkage stoping with sublevel stopingIt allows blasting from lower sublevels while using broken ore for wall support.Suited for moderately dipping ore bodies.
67
In underground mining, a sump is primarily used for:
Discuss
Answer & Solution
Answer: Option B
Solution:
Sump is a low point where water is collected and pumped out.The correct answer is: Water drainage collectionIt prevents water buildup that can hinder operations or weaken ground.Essential for mine dewatering.
68
Which mining layout is most efficient for large-scale horizontal ore bodies?
Discuss
Answer & Solution
Answer: Option B
Solution:
Block Caving is used for large, low-grade, horizontally extensive ore bodies.The correct answer is: Block CavingIt uses gravity to collapse ore, minimizing drilling and blasting.Low cost per ton but higher dilution.
69
Which of the following is a disadvantage of longwall mining?
Discuss
Answer & Solution
Answer: Option C
Solution:
Longwall mining is highly productive, especially for coal.The correct answer is: High initial capital costRequires expensive machinery and roof support systems.However, it offers good safety and recovery rates.
70
What is the function of a ventilation raise?
Discuss
Answer & Solution
Answer: Option D
Solution:
Ventilation raise is a vertical opening used for airflow.The correct answer is: Air circulationIt allows fresh air to enter and contaminated air to exit.Essential for maintaining breathable air underground.
