The drilling technique applicable for mineral exploration is
The drilling technique applicable for mineral exploration is
Show Hint
Diamond core drilling is preferred whenever intact rock samples are required for geological logging and analysis.
Updated On: Dec 17, 2025
- Percussive drilling
- Tricone roller drilling
- Rotary-percussive drilling
- Diamond core drilling
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Mineral exploration drilling requires continuous core recovery to study lithology, structure, grade variation and mineralization.
Diamond core drilling provides an intact cylindrical rock core, making it ideal for geological and mineral exploration.
The other methods—percussive, tricone, and rotary-percussive—are mostly used for quick drilling or blast-hole drilling, not for obtaining high-quality continuous core samples.
Final Answer: (D)

- A direct rope haulage has the following details:
Output = 24 tonne/hour,
Length of trip = 610 m,
Gradient = 1 in 12,
Capacity of mine car = 1.0 tonne,
Tare weight of mine car = 0.5 tonne,
Average rope speed = 1.694 m/s,
Change over time of cars = 3 minutes,
Acceleration due to gravity = 10.0 m/s².

- A longwall panel is to be developed in a flat seam at a depth of \( H \) m. The surface subsidence profile (\( s \)) of the area with the horizontal distance \( x \) is estimated as \[ s = \frac{S_{{max}}}{2} \left[ 1.002 - \tanh \left( \frac{4.8x}{H} \right) \right], \] where \( S_{{max}} \) is the maximum subsidence at the centre of the panel, \( x \) is measured from the inflection point. The value of \( x \) is negative towards the panel centre and positive towards the panel boundary. The ratio between the critical width of the panel and the depth is:
