1.The primary objective of mining engineering is to:
A. Manufacture mining equipment only
B. Extract valuable minerals safely and economically
C. Study only geological formations
D. Eliminate all surface disturbances
Answer: B
Mining engineering focuses on the safe, efficient, and economical
extraction of mineral resources while managing technical and
environmental challenges.
2. The branch of mining concerned with minerals extracted from
deposits near the surface is:
A. Underground mining
, B. Surface mining
C. Marine mining
D. Nuclear mining
Answer: B
Surface mining involves removing minerals from deposits located close to
the Earth's surface using methods such as open-pit and strip mining.
3. The process of locating and evaluating mineral deposits is called:
A. Mineral processing
B. Mine reclamation
C. Mineral exploration
D. Ore transportation
Answer: C
Mineral exploration identifies potential mineral resources through
geological, geophysical, and geochemical investigations.
4. The term "ore" refers to:
A. Any rock found underground
B. A mineral deposit containing valuable materials that can be
economically extracted
C. Waste material from mining
D. Processed metal products
,Answer: B
Ore is a naturally occurring material containing valuable minerals in
concentrations sufficient for profitable extraction.
5. The difference between ore and waste rock is determined mainly by:
A. Color of the rock
B. Economic value and recoverable mineral content
C. Location of the deposit
D. Rock temperature
Answer: B
Economic considerations determine whether a mineralized rock is classified
as ore or waste.
6. Open-pit mining is most suitable for:
A. Deep narrow deposits only
B. Large deposits near the surface
C. Offshore mineral deposits
D. Underground veins only
Answer: B
Open-pit mining is economical for large, shallow mineral deposits where
extensive excavation is possible.
7. Underground mining is generally selected when:
A. The deposit is too deep for economical surface extraction
, B. The mineral has no value
C. No geological information exists
D. The deposit is always horizontal
Answer: A
Underground mining allows extraction of deep deposits while minimizing
unnecessary surface excavation.
8. The main purpose of mine ventilation is to:
A. Increase ore grade
B. Provide fresh air and remove harmful gases
C. Reduce mineral prices
D. Replace explosives
Answer: B
Ventilation systems maintain safe underground conditions by supplying
oxygen and removing contaminants.
9. Methane gas in underground coal mines is dangerous because it:
A. Improves combustion
B. Can form explosive mixtures with air
C. Increases ventilation efficiency
D. Strengthens rock
