11
What is the primary purpose of a sump in a mine?
Discuss
Answer & Solution
Answer: Option C
Solution:
Sump refers to a low point in the mine where water collects.The correct answer is: Water collectionHelps prevent flooding and allows for effective pumping systems.Usually located near shafts or declines.
12
Which method involves retreating while extracting support pillars?
Discuss
Answer & Solution
Answer: Option C
Solution:
Retreat mining removes pillars during withdrawal from a mined area.The correct answer is: Retreat miningCommonly used in coal mines.Requires high monitoring due to collapse risk.
13
Which equipment is typically used in raise boring?
Discuss
Answer & Solution
Answer: Option C
Solution:
Raise boring involves drilling a pilot hole, then using a reaming head.The correct answer is: Reaming headEnlarges hole from bottom to top.Used for ventilation raises and ore passes.
14
What defines a "shaft collar" in mine development?
Discuss
Answer & Solution
Answer: Option B
Solution:
Shaft collar is the reinforced concrete or steel structure at shaft top.The correct answer is: Shaft entrance reinforcementProvides stability and structure for surface installations.Protects against soil collapse.
15
Which layout is common in sublevel stoping?
Discuss
Answer & Solution
Answer: Option D
Solution:
Sublevel stoping uses fan drilling from sublevels into the ore body.The correct answer is: Drill fan patternAllows precise blasting and ore extraction.Suitable for steep, competent ore bodies.
16
What is an "ore chute"?
Discuss
Answer & Solution
Answer: Option C
Solution:
Ore chute is a sloped channel for gravity-based ore movement.The correct answer is: Channel for ore movementConnects stopes to ore passes or haulage levels.Requires maintenance to prevent hang-ups.
17
Which stoping method is most suitable for narrow, steep ore veins?
Discuss
Answer & Solution
Answer: Option A
Solution:
Shrinkage stoping is ideal for narrow, steeply inclined ore bodies.The correct answer is: Shrinkage stopingBroken ore supports miners as work progresses upward.Good for hard rock mining.
18
Which system is commonly used for mine dewatering?
Discuss
Answer & Solution
Answer: Option C
Solution:
Mine dewatering uses sump-pump systems to remove water.The correct answer is: Sump-pump systemPrevents equipment damage and hazards.Essential in both development and production phases.
19
What is the role of a "crosscut" in underground mining?
Discuss
Answer & Solution
Answer: Option B
Solution:
Crosscut is a horizontal tunnel that intersects an ore body.The correct answer is: Horizontal opening to access ore bodyDrilled perpendicular to drifts or drives.Facilitates haulage and ventilation.
20
In mining, what is a drift?
Discuss
Answer & Solution
Answer: Option B
Solution:
Drift is a horizontal passage in a mine, usually along the vein.The correct answer is: Horizontal access tunnelUsed for ore extraction, access, or infrastructure.Developed at different levels as needed.
