31
Which of the following best describes a "development heading"?
Discuss
Answer & Solution
Answer: Option C
Solution:
Development heading is the advancing face of a new tunnel.The correct answer is: Active mining front in developmentIncludes activities like drilling, blasting, mucking.Crucial for creating access or infrastructure.
32
What is the function of "bulkheads" in underground mines?
Discuss
Answer & Solution
Answer: Option C
Solution:
Bulkheads are sealed walls built to control airflow or water movement.The correct answer is: Stopping water or air flow Often made of concrete, they isolate flooded or gassy sections.Essential for mine safety and ventilation control.
33
Which of these is not a common shaft sinking method?
Discuss
Answer & Solution
Answer: Option D
Solution:
Shaft sinking involves vertical access creation using several techniques.The correct answer is: Longwall slicingLongwall is a coal mining method, not used for shafts.Raise boring and caisson are modern shaft techniques.
34
Which parameter most influences the spacing of ground support?
Discuss
Answer & Solution
Answer: Option C
Solution:
Ground support spacing is based on geotechnical stability.The correct answer is: Rock mass qualityMeasured using RMR, Q-system, etc.Better rock needs less support.
35
Which of the following is used for mechanized drilling in longhole stoping?
Discuss
Answer & Solution
Answer: Option C
Solution:
Longhole stoping requires accurate and deep drilling.The correct answer is: Simba rigSimba rigs are computer-controlled for precise parallel holes.Increases productivity and fragmentation control.
36
What is the main function of a raise bore machine?
Discuss
Answer & Solution
Answer: Option C
Solution:
Raise boring is a technique to drill vertical or inclined shafts.The correct answer is: Excavate vertical openingsIt drills a pilot hole, then enlarges it from bottom to top.Used for ventilation shafts and ore passes.
37
Which mining method involves retreating the face and allowing the roof to collapse behind?
Discuss
Answer & Solution
Answer: Option B
Solution:
Longwall mining is common in coal mining with high productivity.The correct answer is: Longwall miningPowered supports advance with the face while the roof collapses in the gob area.This method is highly mechanized.
38
What is the purpose of a crown pillar in underground mining?
Discuss
Answer & Solution
Answer: Option B
Solution:
Crown pillar is a layer of unmined rock left between an underground mine and the surface.The correct answer is: Support overlying rock massIt prevents collapse and surface subsidence.Critical in near-surface deposits.
39
Which of the following is best suited for selective mining in irregular ore bodies?
Discuss
Answer & Solution
Answer: Option C
Solution:
Cut and fill mining adapts to irregular ore shapes and allows selective extraction.The correct answer is: Cut and fillOre is removed in slices and the void is backfilled.High cost but minimal dilution.
40
Which factor most affects the stability of underground openings?
Discuss
Answer & Solution
Answer: Option B
Solution:
Rock strength is a primary determinant of how stable an opening will be.The correct answer is: Rock strengthStronger rocks can support wider spans and deeper development.Measured through RQD and UCS tests.
