41
Which term refers to the downward inclination of a vein or ore body?
Discuss
Answer & Solution
Answer: Option A
Solution:
Dip is the angle at which a vein or ore body inclines from the horizontal.The correct answer is: DipMeasured perpendicular to strike.Essential in geological mapping and stope design.
42

Discuss
Answer & Solution
Answer: Option B
Solution:
Split sets are friction-based rock support elements.The correct answer is: Split setsInserted into a slightly smaller hole, anchoring via friction.Often used with mesh in underground headings.
44

Discuss
Answer & Solution
Answer: Option A
Solution:
Raise boring uses a pilot hole and reamer head to cut upward.The correct answer is: Raise boringNo explosives needed, safer and accurate.Common for ventilation and ore passes.
45
What defines the term "strike" in geology?
Discuss
Answer & Solution
Answer: Option C
Solution:
Strike is the compass direction of a rock layer or fault line.The correct answer is: Horizontal direction of a geological featureMeasured perpendicular to dip.Used in mapping and mine planning.
46
Which of the following methods is most suitable for soft, unconsolidated ground?
Discuss
Answer & Solution
Answer: Option C
Solution:
Cut and fill provides support after each cut with fill material.The correct answer is: Cut and fillIdeal for poor ground conditions.Allows selective mining and ground stability.
47
What is a boxhole in mining?
Discuss
Answer & Solution
Answer: Option B
Solution:
Boxhole is a small raise made upward to connect levels.The correct answer is: Small raise driven upwardCommonly used to initiate raises or ore passes.Usually drilled using handheld or mechanized equipment.
48
Which mining layout includes rooms and pillars of unmined ore?
Discuss
Answer & Solution
Answer: Option B
Solution:
Room and pillar leaves parts of the ore as pillars for support.The correct answer is: Room and pillarCommon in coal and flat-lying bedded deposits.Pillars may be later recovered in retreat mining.
49
Which drilling pattern is used in shaft sinking?
Discuss
Answer & Solution
Answer: Option C
Solution:
Burn cut is commonly used in shaft sinking.The correct answer is: Burn cutCentral holes are left uncharged to create a void.Allows other holes to break into the void efficiently.
50

Discuss
Answer & Solution
Answer: Option C
Solution:
Collar level is the first horizontal opening from a vertical shaft.The correct answer is: Provide horizontal access from shaftActs as a hub for early excavation or logistics.Often used during sinking and construction stages.
