Each section contains 100 MCQs on Mine Development and Mining Methods .
91
Which method involves simultaneous excavation and backfilling?
Discuss
Answer & Solution
Answer: Option C
Solution:
Cut and fill is a sequential method with filling after each cut.The correct answer is: Cut and fillProvides excellent ground support.Suitable for irregular ore bodies and weak rock.
92
What equipment is used for horizontal development in hard rock mines?
Discuss
Answer & Solution
Answer: Option C
Solution:
TBMs are used for rapid, smooth excavation of horizontal tunnels.The correct answer is: Tunnel Boring Machine (TBM)Common in civil and some mining projects.Efficient but costly; suited for long, straight tunnels.
93
Which structure prevents collapse of a shaft during sinking?
Discuss
Answer & Solution
Answer: Option B
Solution:
Shaft liner is a permanent internal support in the shaft.The correct answer is: Shaft linerMade from concrete, steel, or wood.Protects against water, rockfalls, and collapse.
94
What method is used to monitor rock movement in mine openings?
Discuss
Answer & Solution
Answer: Option C
Solution:
Extensometers measure displacement in rock masses.The correct answer is: ExtensometryUsed to monitor roof stability and deformation over time.Essential in geotechnical instrumentation.
95
What is the purpose of a "manway" in underground mines?
Discuss
Answer & Solution
Answer: Option C
Solution:
Manways are vertical or inclined shafts fitted with ladders.The correct answer is: Personnel movementUsed for emergency escape or inspection access.Complement hoisting or ramp systems.
96
What is the primary use of a raise in underground mining?
Discuss
Answer & Solution
Answer: Option B
Solution:
Raise is a vertical or inclined opening connecting different levels.The correct answer is: Ventilation and accessUsed for air circulation, ore transfer, or escape routes.Often developed using raise boring or Alimak.
97
In a mine layout, what is a "winze"?
Discuss
Answer & Solution
Answer: Option C
Solution:
Winze is a vertical or steeply inclined shaft sunk inside the mine.The correct answer is: Internal shaft between levelsUsed for ore transfer and ventilation between levels.Unlike shafts, winzes start underground.
98
What is the purpose of scaling in underground mining?
Discuss
Answer & Solution
Answer: Option B
Solution:
Scaling involves removing loose rock from walls and roof.The correct answer is: Removing loose rockEnsures a safer work area by preventing rock falls.Typically done manually or with mechanical scalers.
99
Which method is most suitable for weak ore and strong wall rocks?
Discuss
Answer & Solution
Answer: Option A
Solution:
Shrinkage stoping retains broken ore in place to support stope walls.The correct answer is: Shrinkage stopingIdeal when ore is fragile but surrounding rock is competent.Ore is extracted after stoping is completed.
100
What is a typical feature of a decline in underground mining?
Discuss
Answer & Solution
Answer: Option D
Solution:
Declines are inclined tunnels used for vehicle access.The correct answer is: Allows vehicular movementUsed for transporting ore, waste, and personnel.Less expensive than shafts for moderate depths.
