71
Which equipment is typically used for ore removal in a sublevel stoping operation?
Discuss
Answer & Solution
Answer: Option B
Solution:
Sublevel stoping uses LHDs to remove blasted ore from drawpoints.The correct answer is: LHD (Load-Haul-Dump)LHDs are efficient, versatile, and commonly used underground.Enhance productivity and safety.
72
Which development activity is done first in underground mining?
Discuss
Answer & Solution
Answer: Option B
Solution:
Shaft sinking is usually the first major activity to access deeper levels.The correct answer is: Shaft sinkingIt allows transport, ventilation, and service installation.Followed by lateral development.
73
What is the purpose of a "collar" in shaft sinking?
Discuss
Answer & Solution
Answer: Option C
Solution:
Collar is the reinforced surface opening of a shaft.The correct answer is: Initial reinforced shaft openingIt stabilizes the ground near the surface and provides a solid base.Critical for long-term shaft safety.
74
Which method is best suited for steep, narrow ore bodies with competent walls?
Discuss
Answer & Solution
Answer: Option C
Solution:
Shrinkage stoping is economical for steep, strong vein structures.The correct answer is: Shrinkage stopingBroken ore supports the walls, reducing support needs.Ore is withdrawn after stope completion.
75
What is the main benefit of using shotcrete in underground development?
Discuss
Answer & Solution
Answer: Option C
Solution:
Shotcrete is sprayed concrete used for reinforcing tunnel walls.The correct answer is: Ground stabilizationPrevents rockfalls and supports weak ground.Can be applied quickly and conforms to irregular surfaces.
76
Which of the following is a major disadvantage of sublevel caving?
Discuss
Answer & Solution
Answer: Option C
Solution:
Sublevel caving can lead to mixing of waste rock and ore.The correct answer is: Excessive dilutionAs overlying rock caves in, it contaminates the ore.Requires good draw control to manage dilution.
77
The function of "crosscuts" in underground mining is to:
Discuss
Answer & Solution
Answer: Option C
Solution:
Crosscuts are horizontal tunnels driven perpendicular to the ore.The correct answer is: Connect drifts or ore bodiesUsed to access ore or other workings from main entries.Essential for mine layout flexibility.
78
Which of the following methods is suitable for mining massive low-grade ore bodies?
Discuss
Answer & Solution
Answer: Option C
Solution:
Block caving is cost-effective for large, low-grade deposits.The correct answer is: Block cavingUses gravity to break and draw ore.Low operating cost but requires significant planning.
79
What is a significant drawback of raise boring compared to Alimak raising?
Discuss
Answer & Solution
Answer: Option C
Solution:
Raise boring requires access to both top and bottom of the raise.The correct answer is: Cannot excavate blind raisesAlimak can be used where only bottom access is available.Raise boring is safer and more mechanized.
80
What type of ore body is best suited for room and pillar mining?
Discuss
Answer & Solution
Answer: Option A
Solution:
Room and pillar works best in flat, continuous ore bodies like coal or potash.The correct answer is: Flat-lying and uniformPillars support the roof, while rooms provide ore access.Allows simultaneous mining and development.
